F- 15 activation
NASA modified F- 15B, active control technology verification machine, three-wing layout. Directly modified from F- 15S/MTD verification machine,
A powerful research computer was installed, the engine thrust was increased, and the newly developed axisymmetric thrust vector nozzle was replaced-this is the main difference between it and F- 15S/MTD in appearance.
Nicknamed NF- 15B "Agile Eagle"
One thing needs to be pointed out: the canard in F- 15 is different from Su -35 and other canards, and has a certain dihedral angle.

F- 15S/MTD:
A short takeoff/precise landing technology verification machine modified by the US Air Force on the basis of F- 15B (actually prototype TF- 15A 1).
Adopt three-wing layout (the canard is a modified flat tail of F/A- 18) and replace it with a digital fly-by-wire flight control system. The engine is F 100-PW-220, but a two-dimensional vector nozzle is used.
This aircraft is mainly used to verify the take-off, landing and air combat maneuverability of aircraft during short takeoff and landing and practical thrust vector control (TVC).

Engineering application of internal test technology of F- 15 aviation intelligent machine
The National Aeronautics and Space Administration and some large companies have carried out the research work on intelligent BIT related technologies. By using artificial intelligence technology to reduce or even eliminate false alarms, CND and RTOK, the readiness of military equipment has been significantly improved, and the cost of use and support has been reduced. The flight expert system (FLES) for airborne fault monitoring and diagnosis, which is funded by the Langley Research Center of NASA 1990, and the fuzzy logic intelligent diagnosis system for the comprehensive health management system of the space shuttle, which is funded by NASA 1995, have been applied to the engineering tests of newly developed equipment and some old equipment modification.
The research results of Wright Air Force Laboratory show that the test technology based on intelligent machine will help to improve the readiness of military equipment, reduce the cost of use and support, and solve the long-standing problem of high false alarm rate in aircraft maintenance (fault detection, location and isolation).
NASA applied the research results of F- 15 aircraft to many later aircraft types, but it did not realize batch equipment on F- 15, but it was very helpful to study the opponent's strategy and tactics.
The improvement of F- 15' s combat power is not obvious. My feeling is that at most, I have done enough work on the repair of existing aircraft, because at that time, the attention of the US Air Force was already focused on the next generation of fighters.
