Tejas squadron formation still a distant dream for IAF | First CO posted For No 45 Sqn at ASTE | Engine test bed readied in Sulur ll a distant dream for IAF

Bangalore: The Indian Air Force’s (IAF) wait to induct the Tejas might get bit longer till the four series production (SP) aircraft roll out from the brand new hangars of Hindustan Aeronautics Limited (HAL). While today’s second initial operational clearance (IOC-2) will signal the end of a grueling wait for the IAF to officially undertake flight evaluation trials, the formation of No 45 Squadron (Flying Daggers) earmarked for Tejas might take another two more years. The same squadron last flew the MiG 21 Bison aircraft operating from Naliya (Gujarat), an airfield closer to Karachi. The Tejas squadron will eventually be operating from the Sulur air force base, near Coimbatore.

Sources monitoring the Tejas programme said that, HAL’s promise of delivering the first production variant of Tejas (SP-1) by March 2014 might be little far-fetched. “We hope to have the first aircraft by end by mid of 2014. The first two aircraft (SP-1, SP-2) might not meet our standards for squadron formation as the metal cutting and hardware were done before we froze the IOC-2 test points. We will raise the first Tejas squadron with four aircraft starting from SP-3 to SP-6,” a top source said. The IAF will use SP-1 and SP-2 for evaluation flight to be undertaken by the Test pilots of Aircraft System and Testing Establishment (ASTE). The limited series production variants LSP-7 and LSP-8 too will be used for evaluation flights by IAF.

The IAF has already identified the first Commanding Officer for Tejas Squadron, now part of the ASTE team, but he’s yet to fly the Tejas. More officers are expected to join the squadron soon, with only few technicians currently being trained to handle the aircraft. For IAF, the maintainability of Tejas is the most primary concern. “The hardware-related issues need to be fixed first. The software can be upgraded without much delay. The critical factor for any aircraft is its maintainability. Truly speaking, before the IOC event, all hardware must be finalized, which might not still be the case with Tejas,” the source said.

A programme management team from the IAF sits at the Aeronautical Development Agency to ensure that the Tejas comes out as a ‘usable aircraft’ befitting the squadron standards. HAL will deliver first 20 aircraft in IOC configuration and another 20 more in the final operational clearance (FOC) format. Appreciating the safety features of the aircraft, the official said that notwithstanding the delays, the safety features of Tejas was world class. “We are way ahead of F-22, Rafale and Eurofighter. We are very lucky to have a safe Tejas flying today. All other similar programmes had crashes during developmental phase. It is a very creditable achievement,” the official said.

Preparations in Sulur are going as per plans with the engine test bed already being readied. The IAF is awaiting the release of Rs 580 crore from the Ministry of Defence to undertake infrastructure work like taxi tracks, hangars and squadron complex. The IAF Chief Air Chief Marshal N A K Browne on Wednesday (18 December) reviewed the progress of Tejas base in Sulur, during his visit to Thiruvananthapuram.

DRDO set to increase Desi components onboard Tejas


Bangalore: The Defence Research and Development Organisation (DRDO) is gearing up to cut the important content onboard Tejas in an effort to erase the tag that India’s home-grown fighter flies on some videshi might. This again is in line with the oft-repeated ‘make-in-India’ philosophy of Defence Minister A K Antony. While the second initial operational clearance (IOC-2) will be definitely a breather for DRDO and its autonomous wing the Aeronautical Development Agency (ADA), the defence scientists are now channelising their energies in developing more indigenous components for Tejas.

DRDO’s most prominent voice Dr K Tamil Mani, Director-General (Aeronautical Systems), says that his organisation is working parallel to get few Indian weapons integrated on Tejas. “Though to integrate Indian weapons is not a planned test point for the final operational clearance (FOC) of Tejas, we have started working on it for some time now. The Astra missile integration with an improvised range of 80-plus km (currently 40-45 km) is the next big challenge. We have also planned some PGMs (precision-guided munitions) for Tejas, including glide bombs and GPS-guided bombs,” Tamil Mani said.

He said various DRDO labs are actively working on the development and testing of these weapons. “We want to take up the Indian weapon integration as a parallel programme, which is progressing as per our plan. In military aviation, the modern thought process is to share the strength. No country makes every component all alone in a fighter plane. So to say that Tejas is not 100 per cent Indian, doesn’t hold any ground. We want to take the indigenous content in Tejas to 80 per cent from the current 60 per cent. It is an achievable target and we have the strength,” he said.

An onboard oxygen generating system (OBOGS) is also in the pipeline for Tejas. The OBOGS development work is being undertaken by the Bangalore-based DRDO life sciences lab Defence Bioengineering and Electromedical Laboratory. “The OBOGS enables the pilots to fly at high altitudes and on long duration sorties without the help of oxygen cylinders. We are also planning to get an Indian company to supply the tyres for Tejas, which currently runs on Dunlop,” Tamil Mani said.

The engine (GE F 404), ejection seat (Martin Baker), missile (R 73 E) and the multi-mode radar (Elta) are among the prominent import content onboard Tejas now.

We are offering a battle-ready Teajs to IAF now: ADA Chief

The Aeronautical Development Agency (ADA) chief P S Subramaniam says that Tejas is completely battle-ready and its increased number of flights in the last 3 years (over 1000) is a testimony to the maintenance, safety and operation features of the aircraft. In an interview to Express on Thursday, Subramaniam said that the Tejas has proved its flying capabilities at all important Indian Air Force (IAF) and a couple of naval bases.

“This year we have touched almost 50 flights and have conducted outstation trails at Jamnagar, Jaisalmer, Gwalior, Leh, Utterlai (near Jodhpur) and Goa. The aircraft has demonstrated the capabilities to operate like a typical squadron. On many occasions the same aircraft has flown more than once in a day. Many have accused us in the past that Tejas was not capable of flying more than once in day. But we have demonstrated flying thrice in a day, which is a pointer towards the ease at which it can be serviced,” the ADA chief said.

He said many local IAF technicians have appreciated the flying and serviceable qualities of Tejas, which was against the general opinion. “Today, the product speaks for itself and we were all glued to improvising its performance for the last many years. The weapon delivery capabilities of Tejas in many modes were demonstrated and over a dozen times we have fired the R-73 E missile. The electronic warfare trials were also conducted at an IAF base in central India,” Subramaniam said.

The ground support equipment specifications have also been evolved. There are about 20 major ground equipment developed for Tejas. “We have also made some new tools for the IAF technicians and many of their concepts have been incorporated. Today Tejas is a fighter evolved from hundreds of feedback we received from designers, engineers, pilots and technicians. We have gone through the motions of making a new generation fighter and faced many difficulties. The induction of Tejas into IAF will being soon and that should silence most of the critics. Plane-making a serious business and making military platforms is a complex exercise. We have covered some distance and Tejas is the answer,” he said.

Is Tejas the first plane to achieve IOC status without having a squadron raised?
 
.
ok let it be only pilot would know the true speed, lets become pilots u know more planes for learning more planes to crash....:yay::yay:


ill try to find it, but u know govt or armed forces will never let enemies know about our weaknesses.....


Pl read this.

Dear dude,
speed of sound is give by equation c=Square root(k/rho) where, k=Bulk modulus and rho=Density of Fluid.
But, Density of fluid changes with respect to pressure because by ideal gas law states that p=rho*r*t
where p=pressure,rho=density,r=gas constant and t=temperature in Kelvin.
but the pressure changes with respect to altitude and is give by, p=-(rho*g*z) where p=pressure,rho=density and z=Height,g=Gravitational Acceleration;
as the altitude increases pressure decreases,decreasing the density and thus cancelling out each other and hence no effect on Ideal Gas(AIR), BUT,
as we know
c=Square root(k/rho) and k=gamma*pressure where gamma=adiabatic index and is further given by
gamma=cp/cv;
cp=specific heat at constant pressure and cv=specific heat at constant volume;
so all in all the Speed of sound depends upon cp and cv which depends on temperature. But temperature depends upon Altitude it decreases for Troposphere and stays constant after tropopause till 20km;
so from 0-11km speed of sound decreases decreasing Mach number and after 11km to 20km it remains constant;
in Aeronautics specially for airplane design we consider altitude only from 0km to 22km.
Thanks.

India rolls out its first indigenous Light Combat Aircraft Tejas

Bangalore: India has rolled out its first indigenous Light Combat Aircraft Tejas in Bangalore on Friday. Defence Minister AK Antony, MoS Defence Jitendra Singh and Air Force chief NAK Browne attended the event.

The launch comes after the ambitious project started nearly 20 years ago. The first batch of the supersonic fighter aircrafts will be produced by Hindustan Aeronautics Limited(HAL) and will be inducted into the Indian Air Force's fleet by 2014.

The first batch of the supersonic fighter aircrafts will be produced by HAL and will be inducted into the Indian Air Force's fleet by 2014.
tomorrow, a significant step towards its induction into IAF

squadron.

Tejas, which received the Initial Operational Clearance on Friday, is a light Combat, a single engine, light weight and highly agile frontline fighter aircraft.

On the eve of the milestone on Thursday, defence major Hindustan Aeronautics Limited said the production facilities have been set up at HAL and the aircraft delivery is expected to commence from 2014.

"We have plans to initially produce eight aircraft per year. Further plans are afoot to enhance the production rate to 16 aircraft per year in consultation with IAF and MOD (Ministry of Defence)", HAL Chairman Dr RK Tyagi said.

He said, "HAL is fully geared up to meet the challenging production schedule and hopes to fulfil the requirements of customers in a time bound manner." The aircraft will, however, have to cross several milestones before it receives the Final Operational Clearance (FOC), expected in 2015.

HAL carried out around 500 sorties of LCA in 2013, the highest for any particular year right from the start of the programme, which has been bogged down by delays. Outstation flight trials were carried out at Leh, Jamnagar, Jaisalmer, Uttaralai Gwalior, Pathankot and Goa for cold weather, armament and weapon deliveries, MultiMode Radar (MMR), Radar Warning Receiver (RWR), hot weather and missile firing flight trials this year itself,Tyagi said in a release.

After IOC II, HAL will go ahead with the Series Production of LCA Tejas, he said. LCA has also successfully demonstrated weapon delivery capability during weapon trials at Jamnagar and Jaisalmer. HAL has been working towards building up infrastructure for production, he said, adding, with most of the aircraft

system performance reaching desired levels, HAL production group would concentrate on stabilising the production line.

The production line at HAL has been moved to new premises with a built up area of around 28,000 Sq m of Hangars, Engineering and Administrative blocks.Upgrade and augmentation of production tooling is underway to enhance the rate of

production and to expedite delivery of aircraft for two IAF squadrons in the next four to five years,Tyagi said.
