Title: Flying body
Inventor: YAMADA KAZUHIRO
IPC: F42B12/00
Filed: 1991-06-14
Abstract: PURPOSE:To obtain a flying body whose structure or mounting instruments are not affected adversely by such a shock as received on water landing by providing its head part with a cushioning means capable of absorbing the shock force received upon landing on the water. CONSTITUTION:A flying body is so designed as to hinder its deceleration throughout its flying and, upon collision with an object 4, the flying body 1 keeps moving to force an outer shell 2 of its head part remaining, at rest against the object to compress a supporting rubber 3a with the resulting elastic deformation thereof. As a result, the shock force exerted on the flying body 1 is relieved and, consequently, the shock force on the instruments mounted therein is also relieved. It is therefore possible to perfectly protect the flying body 1 and its internal instruments from the shock by appropriately selecting the elastic coefficient, length and cross-sectional area of the supporting rubber 3a in relation to the mass and the strength of the flying body 1. In the case of the water landing, it is quite natural that the flying body 1 such as capable of withstanding a rigid solid should be protected from the water.
