يعني قوة الدفع تختلف المحرك m 88 سرعته تصل الي 1.8 ماخ هل قوة دفع محرك m 88 4E اقوى ؟؟
2012: M88-E4 becomes the new standard.
- 20% of the modified engine: rotor and stator parts involving high pressure elongated inspection intervals.
- A TAC (Tactical Air Cycle (*)) from 2500 to 4000 cycles (now similar to the engines of the F-18 and F-16).
- 60% more potential on parts that require the most maintenance
(*) Number of "pulses on the throttle" that can be given to a motor between each inspection.

March 2014: development of new injectors
For a combat unit, its performance can start on high altitude terrain is often of the utmost importance.
In China, for example, Daocheng of the airport is 4441 meters.
Accordingly markets to
exports potentially affected by this type of performance, the development of new injectors has been notified early 2013. Associated with the starter Ruby III, these injectors, called "enriched", must undergo a series of evaluations:
- Takeoff interrupt (rapid deceleration)
- High pressure and high temperature
- Endurance at full load (post combustion system)
- Consumption

Auxiliary Power Unit
An auxiliary power unit power (APU) allows the device to "roll in 90 seconds" without recourse to any assistance.
The APU typically provided a significant electrical power, pneumatic or mechanical.
This APU, Ruby 3, is manufactured by Microturbo. With an output of 6 kVA, its air flow is 0.9 kg / s.
The power transfer for starting the main engine is made according to a mechanical or pneumatic mode. For this reason, the Ruby is 3 cOuple start system ATS-305 providing 126 kilowatts of shaft power with an air flow of 1.1 kg / s.

The transmission M-88 / Burst
Developed and produced by Hispano-Suiza, this complex consists of:
- engine support equipment (Engine Mounted Accessories Drive) on which are mounted the main hydro-mechanical block, the hydro-mechanical block afterburner and lubrication unit,
- and airplane accessories relay ( A ircraft M ounted A ccessories D bank) driving the power generation equipment. Both housings are connected by a drive shaft rotatable at high speed.
Equipped with flexible blades, the drive shaft Hispano-Suiza is unparalleled in terms of damage tolerance and fatigue resistance.
