To solve the problem that an emergency parachute mounted on a flight body has no choice of a landing point because it moves to a downwind direction after deployment and is landed, and to adjust falling speed of the flight body without large change of a parachute system.SOLUTION: A flight body falling assist device includes a cross-shaped parachute X and its deployment mechanism, wherein the deployment mechanism has a first bridal cord 13 obtained by bundling a plurality of first suspension lines 1 and 4 connected to a corner part of the parachute, a second bridal cord 14 obtained by a plurality of second suspension lines connected to an edge part other than the corner part, and a variable mechanism for changing a ratio of a length of the first or second bridal cord, and changes the length of the first or second bridal cord between a flight body and the parachute, and changes a projection blade area at the time of deployment of the parachute.SELECTED DRAWING: Figure 3

    【課題】飛行体に装着される緊急パラシュートは、開傘後風下へ移動して着地することとなるため着地点の選択肢がない。本発明は、飛行体の降下速度調整を、パラシュートシステムに大きな変更を施すことなく可能とするものである。【解決手段】本発明は、十字型パラシュートXとその展開機構を備え、展開機構は、パラシュートのコーナー部に繋がる複数の第1のサスペンションライン1,4を束ねた第1のブライダルコード13と、コーナー部以外の縁部に繋がる複数の第2のサスペンションラインを束ねた第2のブライダルコード14と、第1又は第2のブライダルコードの長さの比率を変化させる可変機構とを有し、飛行体とパラシュート間の第1又は第2のブライダルコードの長さを変化させて、パラシュートの展開時の投影翼面積を変化させることを特徴とする飛行体の落下補助装置を提供する。【選択図】図3
