The invention discloses a helicopter fixed-point constant-speed delivery device. The helicopter fixed-point constant-speed delivery device comprises a paying-off winding drum, a cable descending ropebelt and a damping deceleration mechanism, wherein the paying-off winding drum is arranged in a cabin; one end of the cable descending rope belt is fixed onto the paying-off winding drum, and the other end of the cable descending rope belt is a free end; and the damping deceleration mechanism is arranged on the cable descending rope belt, and descends at a constant speed along the cable descendingrope belt after goods are lifted. By using a mode that the damping deceleration mechanism drives the goods to slowly descend together, the low-altitude fixed-point constant-speed delivery by a helicopter is realized; the delivery efficiency is high; the damage rate of the goods after the delivery is low; in addition, the helicopter fixed-point constant-speed delivery device is applicable to low-altitude delivery in various severe terrains; and the safety of low-altitude delivery by the helicopter is improved.

    本发明公开了一种直升机定点定速投放装置,包括安装于机舱内的放线卷筒、索降绳带和阻尼减速机构,所述索降绳带一端固定在放线卷筒上,另一端为自由端,所述阻尼减速机构安装在索降绳带上,并在吊装货物后沿索降绳带匀速下降。本发明通过采用阻尼减速机构带着货物一起缓降的方式,实现了直升机低空的定点定速投放,其投放效率高,投放后货物的损坏率低,且其适于多种恶劣地形的低空投放,提高了直升机低空投放的安全性。
