| Popis: | In Institute of Space and Astronautical Science (ISAS), a payload recovery system for the sounding rocket of S-520 type has been recently developed, which mainly consists of a two staged parachute deceleration system, a floating buoy system, a location aid system based on LORAN-C system, and other supporting system including electronic instruments, such as a sequence timer. Before the sounding rocket, S-520-4,in which the recovery system first was installed as a part of payload was successfully carried out on 5th of September of 1981,there was conducted a preliminary test at Sanriku Balloon Center (SBC) by utilizing a balloon of 30,000m^3. This was the drop test of a recovery system test unit that was almost the same as the recovery system of S-520-4 from the Balloon, B_-41,in the level flight at a height of 28km above the sea near the east coast of Iwate Prefecture. The drop test aimed to confirm that the recovery system would function well in phases of both parachute deceleration and floating at the sea with the LORAN-C location aid system in operation. The experiment was successfully carried out on 9th of June of 1981. All the subsystems of test unit perfectly functionated. The test unit which was afloat at the sea near the coast of SBC was smoothly recovered by the small boat guided with the LORAN-C location aid system on it. The recovered test unit gave us fruitful results. 資料番号: SA0166565000 |
