Mitigation for Loss-of-Control Accidents in Transport Airplanes
2010-08-12
WIP
ARP6149
Prevention of catastrophic upset mishaps cannot depend solely on recovery training. The proposed document should complement the training initiatives already in place. As a committee dealing with transport human factors and handling qualities, the output must consider both issues. At the same time, we cannot ignore initial and recurrent training issues and the widespread use of ground-based simulators. The plan would follow the approach taken in the 2003 S-7 white paper but would extend the scope to all forms of LOC, not just repeated rudder reversals. As with the white pa-per, the new document would have sections on transport handling qualities, flight control modes, aircraft displays, simulator requirements, and approval for IFR test evaluations as well as covering training issues. This new document would complement, not replace documents such as the Airplane Upset Recovery Training Aid.

A De-Spin and Wings-Leveling Controller for a 40 mm Hybrid Projectile
2013-09-17
2013-01-2262
A Hybrid Projectile (HP) is a round that transforms into a UAV after being launched. Some HP's are fired from a rifled barrel and must be de-spun and wings-level for lifting surfaces to be deployed. Control surfaces and controllers for de-spinning and wings-leveling were required for initial design of an HP 40 mm. Wings, used as lifting surfaces after transformation, need to be very close to level with the ground when deployed. First, the tail surface area needed to de-spin a 40 mm HP was examined analytically and simulated. Next, a controller was developed to maintain a steady de-spin rate and to roll-level the projectile in preparation of wing deployment. The controller was split into two pieces, one to control de-spin, and the other for roll-leveling the projectile. An adaptable transition point for switching controllers was identified analytically and then adjusted by using simulations.
