To solve the problems in a conventional multistage rocket that a construction mass of an airframe becomes large as much as a mass portion of a system tunnel for allowing passage of wiring between stages, and that an aerodynamic characteristic is lowered.SOLUTION: In a multistage rocket R in which a plurality of stage parts R1-R3 are coupled separably, each stage part R1-R3 includes each self controller C1-C3 for controlling the self stage part respectively, and stage parts R2, R3 on the furthermore upper side than the lowest stage part R1 include separation detection parts SA, SB for detecting separation from the stage parts R1, R2 on the lower side, and the self controllers C2, C3 start control based on detection signals from the separation detection parts SA, SB. Consequently, a system tunnel for wiring between stages is abolished, and reduction of a construction mass of an airframe, and improvement of an aerodynamic characteristic are achieved.SELECTED DRAWING: Figure 1

    【課題】従来の多段ロケットは、段間の配線を通すためのシステムトンネルの質量分だけ機体の構造質量が大きくなると共に、空力特性が低下するという問題点があった。【解決手段】複数の段部R1〜R3を分離可能に結合した多段ロケットRであって、各段部R1〜R3が、自段部の制御を行うための自己制御器C1〜C3を夫々備えると共に、最下段部R1よりも上側の段部R2,R3が、下側の段部R1,R2との分離を検出する分離検出部SA,SBを備え、自己制御器C2,C3が、分離検出部SA,SBの検出信号に基づいて制御を開始するものとし、段間配線用のシステムトンネルを廃止して、機体の構造質量の低減と空力特性の向上を実現した。【選択図】図1
