Squeezing the most out of a fighter jet can be a risky movement. That’s why the Flight Control Laws clearance assessment (part of the embedded software validation and verification process) is so important to grant the aircrew’s safety under any condition.

The Northrop Grumman B-2 Spirit is a multi-role strategic bomber developed in the United States by Northrop Grumman with low visibility radar stealth technology capable of penetrating air defenses to deploy both conventional and nuclear weapons. Due to its considerable cost and operating expense, the project for this aircraft was quite controversial in the United States Congress and among members of the United States Joint Chiefs of Staff during its development and commissioning.

This look-down view of the X-36 Tailless Fighter Agility Research Aircraft on the ramp at NASA’s Dryden Flight Research Center, Edwards, California, clearly shows the unusual wing and canard design of the remotely-piloted aircraft. NASA and Boeing developed the Reconfigurable Control for Tailless Fighter Aircraft (RESTORE) flight control software as a demonstration of the adaptability of the Model Reference Adaptive Controller with a neural-net algorithm to compensate for in-flight damage or malfunction of effectors, such as flaps, ailerons, and rudders.

Lighter wings, higher wing aspect ratios, and less fuel consumption — all of this can be achieved when you fly flutter-free, but well beyond the flutter speed, all thanks to robust adaptive control technologies.

Stop searching through mountains of research publications, books are the best tool to learn the basics, and these are the ones you should read if you are interested in the field of adaptive control.
