Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, The flight demonstration of reusable rockets requires landing technologies such as deceleration and descent by engine throttling and shock absorption by landing legs. To achieve these landing technologies, this study aims to create a landing and descent environment using a rocket sled for reusable rockets. In this paper, we describe the landing and descent environment that can be achieved with the proposed experimental system, and also describe its current development status., 資料番号: SA6000184018, STCP-2022-018

In addition to the conventional method, the injector Cd was set small based on past test results. As a result, the LOX flow rate error at 70% throttle was improved from 10% to 1.3%. In addition, for flight operation, the propellant orifice diameter was examined for the feed-line resistance of the control valves., 資料番号: SA6000184027, STCP-2022-027

A temperature deviation exists inside the combustion chamber of the gas generator installed in this engine. Therefore, we installed elbows, which are known to be effective in improving temperature distribution to confirm the temperature uniformity effect of the elbows. As a result, it was confirmed that the elbow improved the combustion gas temperature by 630K., 資料番号: SA6000184028, STCP-2022-028

Abstract

In this paper is presented a microgravity experiment system utilizing a high altitude balloon. The feature is a double shell structure of a vehicle that is dropped off from the balloon and a microgravity experiment section that is attached to the inside of the vehicle with a liner slider. Control with cold gas jet thrusters of relative position of the experiment section to the vehicle and attitude of the vehicle maintains fine microgravity environment. The design strategy of the vehicle is explained, mainly referring to differences from the authors' previous design. The result of the flight experiment is also shown to evaluate the characteristics of the presented system., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: DS1540389004
