in answer to the mention of dhruv in Ecuador : I don't have the habit of blindly supporting anything that is made in India. Indian government sector is mismanaged and totally devoid of common sense , to say nothing of the jackass bureaucracy . the fact is most of the crashes of the Dhruv was in its older version. The earlier Dhruv was bound to have issues as it was our first product, but the current Dhruv are essentially a different helicopter with the same design. Apart from the basic airframe design, nothing is same anymore. The power-plant, transmission, avionics and the cockpit is entirely different. And the modification of flight control laws need not be even mentioned as it is common for any platform. There's a total of 14 crashes with 4 of them on Ecuador fleet. Let's look at them in detail, shall we? 2005 1 2007 1 2009 1 (Ecuador) 2010 2 2011 2 2012 1 2013 1 2014 2 (1 Ecuador) 2015 3 (2 Ecuador) Total 14 (4 Ecuador) ************************ Ecuador (4 Crashes) 2 Crashes were due to Pilot error and 2 due to mechanical error. However the mechanical error crashes are suspected to be due to lack of maintenance as they happened after the HAL maintenance contract was over. "HAL, which had provided ground support for these choppers in Ecuador, have said that the two choppers that crashed allegedly because of mechanical defects went down after the ground support period with Ecuador had ended." As for the crashes that occur after maintenance contract, it is the responsibility of the operator to ensure proper maintenance of their aircraft. Ecuador had opted for a short maintenance contract to save money and the entire contract was billed at $45 million (USD). The length of the maintenance contract is always the choice of the customer and the manufacturer can't dictate the terms. http://www.ndtv.com/india-news/after-4-crashes-ecuador-grounds-fleet-of-indian-dhruv-choppers-cancels-contract-1232715 India (10 Crashes) 2015 - Unknown 2014 - Technical Error 2013 - Technical Error 2012 - Unknown 2011 - Technical, Weather 2010 - Technical, Unknown 2007 - Pilot Error 2005 - Technical Error 5 confirmed incidents of Technical Error, 6 confirmed incidents of not being design fault - against over 300 helicopters in service for nearly 15 years, Yes this is a good record for a first helicopter designed and made inhouse. As the older versions get phased out, the safety record will only get better. Also consider the fact that last 2-3 years saw over 30 new model Dhruv being inducted on an yearly basis with no crashes against it. SARANG helicopter acrobatic display team of the Indian Air Force dhruvs (ALH) -presently the only such team in the world i think. MOTTO (in jest) "BUT FOR THE ROTOR, WE COULD HAVE BEEN CLOSER" 1 Like

AESA radar and optronics on board Indian upgraded ZSU-23-4 the ZSU-23/4 Shilka mobile gun system has received new propulsion, and fire control system, based on an integrated multi-sensor system developed under cooperation between the Indian company Bharat Dynamics and Israel’s Aerospace Industrie’s MBT. the upgrade comes installed with a new 359 BHP Caterpillar main diesel engine and auxiliary power unit delivering 51 BHP, a pedestal mounted radar, thermal imager, daylight TV and laser rangefinder enabling the vehicle to operate in passive or ’emitting’ search mode. The radar can detect targets at a range of 15km and track multiple targets at 9 km. The passive optronic sensor can operate independently of the radar detecting and tracking aerial targets as far as 8 km away. The four 23mm guns are effective at a range of 2,500 meters and altitude of 1,500 meters. The vehicle is fitted with two operator consoles, providing complete situational picture, in addition to target tracking for specific engagements. The system is capable of receiving target cueing from remote sensors, such as air surveillance radar. The new system has an option to integrate missile systems. 1 Like

tdayof: Indian laser weapons capability is a work in progress, some r classified . some info on ADITYA Gas Dynamic High Power Laser based Directed Energy System LASTEC's ADITYA project is an experimental test bed to seed the critical DEW technologies. The Gas Dynamic High Power laser based Directed Energy System can be broadly divided into two major subsystems: 1.Laser Power Source 2.Beam Delivery System Laser power of the order of 100 kW is required to cause the stipulated damages at 0.8 km and 2.5 km distance using a 0.7 m aperture telescope. The beam delivery system has to simultaneously perform several roles. It acquires and tracks the distant static and moving target in real time and points and focuses the laser beam on the target. The adaptive optical system has to compensate for the jitter and wave front distortion of the laser beam from the source. The technology related to laser source, beam delivery and issues related to system integration on mobile platforms have been addressed during the execution of the project. It would be a useful input to future laser weapon programmes of DRDO. Laser Power Source of 100 kW The laser source consists of system integrated on different transportable platform, viz., Laser Generation System Vehicle (LGV) and Air Supply System Vehicle (ASV). The system has been realised, integrated, and tested. Laser power of the order of 100 kW has been achieved. Damage potential of the laser has been tested up to 800 m distance. Laser Generation Vehicle (LGV) has been developed to generate a high energy beam. The input energy is pumped into the system through combustion of large amount of air and toluene. The system mainly consists of laser tunnel, toluene storage, gasoline storage and pressurisation and feed system, parts of combustion, ignition, aerodynamic window, cavity bleed, fuel purging, pneumatic air supply lines, control panel, etc. The laser tunnel consists of a combustor, a nozzle bank with cavity, resonator, diffuser and TCD. These systems are mounted on a low bedded transportable trailer having suitable canopy. The LGV is dependent on ASV for oxidiser air supply and command control vehicle for operation commands for generation of high energy beam. The associated technologies developed are: 1.Toluene - Air Combustor System for Generation of Lasing Gas Mixture @ 40 kg/s a.To withstand the high temperature (tens of hundreds) and high pressure (many tens of bar) condition for the repetitive firings. b. Soot free combustion & generation of CO2, N2, H2O and O2 in required proportion. c. Reliable ignition system through pilot flame igniters to avoid any ignition delay combustion. d.Four level of safety interlock for controlled combustion 2.Supersonic Multi Bank Contoured Nozzle The technical challenge lies in maintaining a small uniform throat gap with a tolerance of few µm in all the nozzle blades arranged as an array. The blades can be dismantled for replacement. The blades, aerodynamically contoured, were fabricated with the help of wire cutting machining. The blades have been fabricated with inconel material. 3.Resonator Cavity along with Mirror Protection System A mirror protection system consisting of pneumatic shutters and cavity bleed was incorporated in the laser cavity to safeguard the optical mirror. The shutter protect the mirror from soot and shock which comes off with the initial flow. The cavity bleed takes care of the mirror during fi ring. 4.Direct Discharge Supersonic Diffuser An efficient atmospheric discharge is very important for the transportability of the system. It recovers pressure from very low values to atmosphere pressure for atmospheric discharge. The art of diffuser design has been understood through theory and experimentation. 5.Vortex Aerodynamic Window Aerodynamic window permits the extraction of laser beam from the cavity of a high power laser through a non-absorbing gas curtain that supports a pressure difference between the cavity and ambient atmosphere. A vortex type aerodynamic window was developed and used with unstable resonator. 6.Vibration Isolated Resonator A vibration isolated structure is mounted in such a way as to prevent transmission of tunnel and platform vibrations to the resonator. This helps in providing the desired beam stability. 7.Data Acquisition & Control System Distributed type of data acquisition and control system was developed. Command control vehicle controls the laser fi ring operation through fi ring and safety cyclograms. Different type of temperature and pressure sensors and control valves mounted on ASV, LSV and Beam Delivery Vehicle are monitored and controlled through command control vehicle. Air Supply System Vehicle Air storage and supply system delivers the compressed air at different pressures and different fl ow rates to various systems. It consists of high pressure air generation, storage and supply system. In this system large quantity of air is stored which is required at the time of laser test fi rings. Air is required in many sub-systems like main air to combustor, air to igniters, air to aero-dynamic window, air for pneumo-pusher, cavity bleed, air for mirror protection and aerodynamic window shutters, air for Remotely Operated Valves (ROV), air for purging of main fuel and igniter fuel lines, intermediate cooling, etc. This vehicle is capable of supplying up to 50 kg/s mass flow rate of regulated air for combustion, aero window and other miscellaneous purposes. Command Control System The command control vehicle is an ISO type air conditioned EMI protected shelter to control the operation of laser source and beam delivery on the target from a safe distance. This is achieved through two control consoles for the GDL source and beam director mounted into the command control vehicle. The GDL control console is capable of laser testing the operation of various valves and conducting laser fi ring. It is very critical to acquire data from the fi eld sensors on LGV, ASV, BDV, and controlling all the subsystems for remote fi ring control. The safety interlocks have been implemented based on pressure in igniter and combustor for avoiding any pulse which can damage the system. The beam director console is capable of independently acquiring the information of the target and the delivery of laser beam on to it. Power Supply System Vehicle The power supply system is mounted on a DG set vehicle. It houses three DG sets. Two numbers of higher power DG sets are used to run the compressor placed on air storage and supply trailer. The third lower capacity DG set caters to the charging needs of various UPSs placed in other trailers/ vehicles and other electrical requirements of the DEW system. Beam Delivery System The beam from laser source is coupled to the beam delivery system. The focusing telescope is mounted on a gimbal which should be agile enough to keep the beam focused on the same spot. The gimbal has to work in closed loop with video tracking system. The main objective of the Beam Directing System (BDS) of Project ADITYA is the auto focusing of the high power laser beam onto a distant moving target in the required operating range. The BDS consists of mainly two assemblies, one is beam transport system and other is stabilised gimbal platform assembly. The stabilised gimbal platform along with beam directing electronic system is responsible for controlling the overall functionality of the system. 1.The beam directing telescope is one of the most critical subsystems of the laser beam director which is responsible for coupling the laser power from the source to the target and for precise pointing/ focusing of laser beam to achieve the required power density on to the area of interest on the moving target at the operating range and for the entire duration of the laser radiation. 2.Target acquisition and video tracking is used to detect, identify and track the moving airborne targets, so that high power laser beam can be fired on the vulnerable spot of the target. Once the target is acquired, detected and identified, the lock on and tracking gets initiated. As the target comes closer to the beam director, then area of interest, i.e. vulnerable spot on the target is locked and tracked.

nemesis2u: The Arhlac is an interesting design but its design isn't what we need. Its primarily a border watch/anti poaching ops bird not for COIN/CAS. Ok,nemesis2u,here's our task. Buy the Pucara production rights from the Argentines and reverse engineer to the specs below. Idk why but the pic won't show! Anyway no prob. Origin Argentina Type close-support and light attack aircraft Max Speed 270 kt / 311 mph Max Range 350 km / 217 miles Dimensions span 14.50 m / 47 ft 6.9 in length 14.253 m / 46 ft 9 in height 5.362 m / 17 ft 7 in Weight empty 4,020 kg / 8,862 lb maximum take-off 6,800 kg / 14,991 lb Powerplant two 729-kW (978-shp) Turbomeca Astazou XVIG turboprops Armament two 20-mm Hispano MS 804 cannon with 270 rounds per gun and four 7.62-mm (0.3in) FN M2-30 machine-guns with 900 rounds per gun, plus provision for up to 1500 kg (3,307 Ib) of disposable stores carried on three hardpoints However for these times it needs greater speed,payload of at least 3000 kg ,an electro optical suite and auto chaff flares dispenser. Fyi,the WW2 P 38 managed over 450 mph!! Nearly the speed of sound. The finished product should sell for 6 mn ,max 7.5mn$ a piece with the highest CPFH of 500-750 $. Anyone else chip but pls stick to the parameters |

@tdayof Terrain masking is simply hiding behind terrain features. "Terrain masking" is a means of avoiding active radar by positioning the aircraft so that there is natural earth hiding it from the radio waves sent by the radar system. This technique is used by military pilots to fly to their target stealthily, using the topography to mask their approach from detecting radar microwaves. basically it is achieved by flying through low elevations, keeping the higher elevations between you and whatever you don't want looking at you. These detectors could be radar, lasers, IR cameras, or humans. A primary advantage is that the detectors mentioned above can't pinpoint your position. These detectors are usually associated with things that can hurt you, so staying out of sight (or out of line-of-sight of their weapons) increases your life expectancy. Other advantages include: 1.You present more of a fleeting target. 2.Not many other aircraft are going to come down and try to tangle with you. 3.Your target has a harder time seeing you coming. 4.Radar-guided weapons have difficulty picking your image out from the ground clutter. A primary disadvantage is that you need to fly really low to hide behind terrain features. Since the ground has a near 100% probability of killing you if you run into it while traveling at speed, this can often offset the advantages of hiding from something shooting at you with a worse kill probability. Other disadvantages include: 1.You tend to burn more gas when flying low. 2.You can't see as far. 3.You're in range of a LOT more stuff that can hurt you. MANPADS, AAA, even an AK47 4.Bird hits 5.You don't have as much room to maneuver. 6.If you have an emergency (like an engine flame out), you have fewer options and less time to sort it out. (The first response is usually to climb and then get killed from whom ever you were trying to hide from in the first place ) This is also called "flying under the radar." Because of the curvature of the earth there is a maximum distance that a ground based, line-of-sight radar can detect a low flying target. Beyond that distance, the target would literally be flying under the radar waves. What further complicates the problem is "ground clutter." The radar return from trees, buildings, and just the ground will obscure the low flying airborne target. It gets lost in all 'clutter' of those many radar returns other than the aircraft. as far as i am concerned Nap-of-the-earth, Terrain masking , flying under the radar are interchangeable since they serve the same purpose. fighter jets fitted with Terrain-following radar (TFR) are only capable of doing the above . eg rafale certain military helicopters also have terrain-following radar. Due to their lower speed and high maneuverability, helicopters are normally able to execute terrain masking better fixed wing aircraft. regarding the osama raid , some sort of stealth helicopter was used , but it was limited , because helicopters with their moving rotors are inherently not stealthy. they are also not completely radar evading due to the above reason. US probably employed EW assets like Prowlers and Growlers to jam / blind the Pakistani radars (Chinese). me thinks it is entirely possible that US also switched off/disabled the radars (US supplied) . the helicopters then used terrain masking to ingress into Pakistan , unobserved visually / electronically . Pakistan assets r deployed mainly in the east and still there are gaps , MIG25s used to breach their airspace ( upto Afghanistan border ) on a regular basis sometimes to spook them they would turn on their afterburners and climb to max altitude and go supersonic. they could do nothing. |

kikuyu1: there are many similiar aircrafts like Pucara to chose from . lets take the example of Pucara what you can do is after buying the productions rights aka blue prints etc is 1.make use of composites and other high strength light weight alloys to replace the suitable parts of the fuselage etc. this will help you to set up national base in the areas of composites and aerospace metallurgy. 2.go for a glass cockpit with modern multifunction MFDS together with the related subsystems like digital processors etc required to run them. u can either develop them in house or u can bring them from abroad and then integrate them . system integration is a difficult thing to master , and if done properly gives you the leverage to expand to other platforms be it aerospace, naval or land systems. 3.u can then go for integrating weapons of your choice on the Pucara by undertaking flight evaluation , testing , certifications of the said weapons. this again is a complex task and if done successfully will allow you to gain proficiency to under take similar weapon qualification tests on other aerial platforms. 5.u can also go for installation of optonics etc , most of the optronics are now days drop and install type , but again system integration skills will allow you to exploit the optronics for ur specific needs all by urself or to get the vendor to make necessary changes to suit your specifications.u will build necessary skills for trouble shooting any problems be it be related to identification , isolation fault analysis and then rectification. it will help to develop hardware in the loop (HIL) stimulation, Software in the Loop (SIL) stimulation , wind tunnel testing , Computational fluid dynamics (CFD) and their analysis relating to clean weapon separation/weapons carriage etc, other stimulation and testing techniques in house for future use. etc etc . advantages of the above suggestions of mine 1.u get a better , more powerful aircraft tailor made to ur needs inhouse. 2.u develop R and D base to exploit what u learnt from doing the above for future exploitation 3.u save foreign exchange , bring employment to ur country 4.u get sovereignty over the said platform 5.u can keep on improving the aircraft to suit ur needs with time and changing threat perceptions 6.u get national pride and inspire similar projects 1 Like |
