 note = {次期TR-1A(宇宙実験用小型ロケット)飛行の成果にとって重要な微小重力場での燃焼伝搬の特徴および燃焼合成における合成過程を確認するために、(1)Ti-B-Al複合化合物の燃焼合成、および(2)1,300Kおよび1,800Kクラスの化学炉としてTi-B-AlおよびTi-C系の燃焼合成の適用実験をパラボリックフライトによる微小重力場で行った。急速加熱の後に急速冷却機能を備えた提案の化学炉を使って、主としてZr-Al-Fe2O3混合粉末系のテルミット反応法、およびTiAlおよびTiAl-TiB2燃焼合成を検討した。本研究の結果として、微小重力環境での燃焼伝搬速度は地上実験における伝搬速度よりも小さく、下方向伝搬に近いことを確認した。微小重力場でこの化学炉により達成した最高温度は地上実験における最高温度よりかなり低く、本急速冷却手法は地上実験に比較して効果が少なかった。X線回折によれば、微小重力場で合成したTi-AlおよびTi-Al-B系生成物は適正組成比にかなり近いものであった。, In order to confirm the characteristics of combustion propagation and synthesis process in combustion synthesis under a microgravity environment which should be important for the performance of the coming TR-1A (Test Rocket-1A) flight No.3, combustion synthesis experiments have been carried out under a parabolic flight microgravity environment: (1) combustion synthesis of Ti-B-Al composite materials; and (2) application of combustion synthesis of Ti-B-Al and Ti-C systems as 1,300 K and 1,800 K class chemical ovens. With the aids of the proposed chemical ovens which provide rapid cooling after rapid heating, the process of thermite reaction of Zr-Al-Fe2O3 powder mixture system, and the TiAl and TiAl-TiB2 combustion synthesis have mainly been investigated. As a result of the present work, it is confirmed that the combustion propagation velocity under the microgravity environment is smaller than that on ground and close to its downward propagation. The maximum temperature attained under microgravity environment by the present chemical ovens is rather small than that on ground, and the present rapid cooling technique is less effective compared to the ground tests. By X-ray diffraction, the products of Ti-Al and Ti-Al-B systems synthesized under microgravity environment are in much proper constituent ratios., 資料番号: AA0000742001, レポート番号: NASDA-TMR-960025},
