Abstract
Abstract A capsule and rocket extraction system for providing an inflight escape system for the pilot of a damaged aircraft. The system comprises a capsule that is separable from the main fuselage of the aircraft and a rocket for extracting the pilot from the capsule. A control system is carried by the capsule for sensing the capsule's speed, altitude and attitude, and for actuating only the rocket to extract the pilot directly from the capsule when the speed, altitude and attitude are at predetermined conditions, and for sequentially actuating a capsule separation device to separate the capsule from the main fuselage and then actuating the rocket to extract the pilot from the separated capsule when the speed, altitude and attitude are at different predetermined conditions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
190 words
In an aircraft having a main fuselage and a capsule separably coupled to the fuselage and carrying the pilot, the improvement comprising: separation means, coupled to the capsule, for separating the capsule from the main fuselage; powered extraction means, coupled to the capsule and coupled to the pilot, for extracting the pilot from the capsule; means, coupled to the capsule, for changing the capsule speed, altitude and attitude once the capsule is separated from the fuselage; and control means, coupled to the capsule, for (A) sensing capsule speed, altitude and attitude, (B)(1) actuating only said extraction means to extract the pilot from the capsule when the capsule speed, altitude and attitude are at predetermined conditions, and (B)(2)(a) sequentially actuating said separation means to separate the capsule from the main fuselage when the capsule speed, altitude and attitude are at different predetermined conditions, (B)(2)(b) actuating said changing means to change the capsule speed, altitude and attitude as necessary to be within the predetermined conditions, and (B)(2)(c) then actuating said extraction means to extract the pilot from the separated capsule when the capsule speed, altitude and attitude are at said predetermined conditions.
