Safety devices for aircraft and aircraft

Abstract

To provide a safety device for an air vehicle which achieves desired operation without fail while achieving reduction of the weight and making assembly work easy.SOLUTION: A safety device 1 for an air vehicle includes: a housing including a top plate part, a bottom plate part, and a peripheral wall part 12; a deployed body; an ejection device 30 which ejects the deployed body; a first member and a second member 50 having strength higher than that of the bottom plate part 21; fastening members 90; and connection members 80. The first member includes: an attachment part 40 which attaches the safety device 1 for the air vehicle to an air vehicle including a propulsion mechanism; and a first fastened part 31a3. The second member 50 includes a second fastened part 51. The fastened members 90 fasten the first fastened part 31a3, the second fastened part 51, and the bottom plate part 21 in a state that the bottom plate part 21 is sandwiched between the first fastened part 31a3 and the second fastened part 51 to fix the bottom plate part 21, the first member, and the second member 50 to each other. Each connection member 80 is connected at one end to the second member 50 and at the other end to the deployed body.SELECTED DRAWING: Figure 5
