Douglas Aircraft Company Advanced Concept Ejection Seat (ACES II). Revision C.

摘要

ACES II (Advanced Concept Ejection Seat) is a high-performance escape system. The increased performance capability greatly improves the survivability of aircrews during escape from aircraft under adverse conditions throughout the flight envelope. ACES II is a rugged, lightweight, easy to maintain ejection seat with advanced-technology subsystems. The subsystems were designed, tested, and qualified in the USAF/Douglas ACES I program, and are integral in the all-new seat structure of ACES II. ACES II seat systems are currently being manufactured for installation in F-15A/B, F-16A/B, and A-10 aircraft as the standard USAF Government-furnished ejection seat. It includes the following features: Multiple operating modes to optimize performance over the 0 to 600-KEAS escape envelope; Self-contained sensing of escape conditions for recovery mode selection; Electronics for sequencing and precision timing in each mode; Gyro-controlled vernier rocket for positive stabilization at low speeds; Hemisflo drogue parachute for stabilization and deceleration at high speeds and high Mach numbers; and Mortar-deployed recovery parachute for consistent, positive operation.
