Inventor: OONUKI HIROYUKI
IPC: B64G1/58
Filed: 1994-09-19
Abstract: PURPOSE: To realize a low cost and light weight, and surely discharge air by providing a cross notch onto the first layer of a thermal blanket and moreover a cross notch onto the succesively overlapped second layer on a position displaced from the first layer, and overlapping plural blankets alternately in order respectively. CONSTITUTION: In a thermal blanket 2 of an artificial satellite, when a pressure difference is caused, the air in the blanket 2 overcomes the force of a coil spring 11 to open a lid 10 to discharge the air. When the air becomes empty to make the pressure difference absent, the lid 10 can be closed by the spring force of the coil spring 11. Only simple constitution, wherein the lid 10 is attached by the coil spring 11, eliminates the conventional work for air discharge holes, wherein many 1ϕ holes are bored at 40mm pitches by using a needle, reducing a cost. Also since the air can be surely discharged to avoid the occurrence of the pressure difference between inside and outside and holding force by a detachable tape can be lessened, the number of the detachable tapes can be the required minimum of necessity to realize lightening.
