Rafale Engine


Needs versatile and powerful engine of the aircraft response to the M88-2. This completely new engine was developed specifically for the Rafale.

The main characteristic of an engine operating at low altitude is above all a low specific fuel consumption. The new turbofan engine, turbofan responds to this with a high compression ratio of 24.5, and components in high yield.


By cons, an engine designed for high altitudes requires a high specific thrust, and a low dilution rate. For this, a dilution rate of 0.3, a high turbine inlet temperature of 1577 ° C and post-combution (PC) on the two flows were adopted.

Such performances were achieved thanks to new techniques include: single-piece bladed compressor disks (DAM), annular combustion chamber clean, blades and turbine nozzles HP (High Pressure) single crystal alloy and a clever cooling system disks HPC powder metallurgy (very reliable and light), ceramic coatings and composite materials for the components of nozzles and cold runner.

The motor is controlled digitally by two computers, programmed with 160 general laws, the system component "FADEC". This allows easy control, optimal, unrestricted engine throughout the flight envelope. For example, it allows both engines were started in only two minutes, and to accelerate from idle to full PCs in just three seconds. This regulation is an important factor in reducing pilot workload. But not only for the pilot: Also for the engineer because the system does not only regulate but also monitors the engine whenever possible, to identify and isolate faults, compute performance, track aging, vibration monitoring etc ... in real time!).

The launch of these engines is accomplished through the APU (Auxiliary Power Unit), which also manages the packaging of the carrier when the aircraft is on the ground.

It is interesting to note, in terms of progress, the M88 is a driver whose mass (897kg) and length (3.53 m) decreased by 45% compared to the Atar 9K50 fitted to the Mirage F1. However, its thrust / weight ratio increased 88% to $ 9.

Beyond its thrust performance and fuel economy is also an engine that's discreet. Indeed, it has all the latest technical advances to reduce its RCS, and especially its SIR (infrared signature). In most situations, the M88 does not affect the infrared signature of the aircraft.

By cons, and of course the engine is one of the first components whose development is long-planned, as it is conceived as a father.

If studies for M88-3 to 90kN and 115kN M88-4 were unsuccessful, they are re-oriented M88 ECO. As such, both engines are tested, one having already demonstrated the ability to reach 90kN (about increased air flow, imposing an air intake slightly larger), and the other aims to increase its life by 50%. The technologies developed are, among others, monocrystalline blade thermal barrier to withstand temperatures of 2100 ° C, the new controllers ... etc..


If the version with extended life interests the French armies, the version "90kN" is mainly for export for use under the equatorial temperatures and in case of non availability of tankers. That said, this version could benefit the Navy aircraft catapult very heavy (20% extra thrust would be substantial) or the Air Force as well, to provide energy for the future pod interference power.

Typhoon deal boost BAE jobs

Tuesday 9th November 2010


AN EAST Lancashire-made fighter jet is set to clinch a bumper £3billion deal with the Indian military, providing a major jobs boost.

Air force chiefs in the Asian country are believed to be on the verge of buying 126 Eurofighter Typhoons, the aircraft built by engineers at BAE Systems’ plants in Samlesbury and Warton.

Although any deal would lead to a Typhoon base being built in India, it would also lead to an increase in workload in Lancashire.

Hundreds of Samlesbury engineers work on the Typhoon fuselage. Final assembly work on the aircraft takes place at BAE’s Warton plant.

Plumbing firm wins homes refurbishment contract BURNLEY-based plumbing merchant James Hargreaves is flushed with success after winning a home refurbishment contract in Hyndburn.

The firm, based in Parliament Street, Burnley, has teamed up with another company to supply heating and bathroom kits for all properties run by the housing association, Hyndburn Homes, for the next three months.

Manager Dave Blackburn said: “It is certainly keeping us busy.”

UK’s defence secretary to visit India

NEW DELHI: Britain’s Defence Secretary Liam Fox will be in New Delhi later this month amidst buzz that Eurofighter Typhoon has emerged as frontrunner in IAF’s multi-billion dollar bid for 126 fighter jets.


South block is yet to confirm, but reports have claimed that Eurofighter — Typhoon — produced by a consortium of Britain, Germany, Spain and Italy — had come on top after technical evaluation by the IAF.

The IAF’s technical report on the performance of six combat jets — F-18, F-16, Mig- 35, Rafale, Typhoon and Gripen — was submitted to the Ministry of Defence recently.

It has been reported that IAF has found Typhoon best suited for its requirements on technical grounds.

The British Defence Secretary would get a true sense on this crucial deal during his meetings with Indian officials and would try to push hard for contract.

The $11.3-billion deal is critical for the six contenders, more so for the European consortium struggling to keep the supply line running.

The Indian deal is big as it could sustain a large number of jobs back home as the aircraft are made in Lancashire.

Fox’s visit comes at a time when huge cuts in British defence budget has become a debating point. The defence ties between India and the UK have come alive in the recent months.

An air combat exercise with Royal Air Force concluded just recently at Kalaikunda air base in West Bengal. The RAF had brought in Typhoons for the first time for the exercise to showcase its capabilities.

The Typhoon campaign in India is being spearheaded by the Germans, but UK is also playing its part in clinching the deal. After the evaluation of the technical bids, the MoD will open the commercial bids.

A large section in India believes that political considerations will overrule all other factors in deciding the winner.

Intense lobbying is underway to put pressure on India.
 
i so want the RAFALE to win.


but mark my words, the yanks (F-18) will take this away.
