Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] (1) Establishing the trajectory model of the traction parachute

[0021] like figure 2 As shown, first of all, it is necessary to clarify the change state of the process from the release of the towing parachute 6 to the unlocking movement of the cargo L, and establish the trajectory model of the towing parachute 6 . In this model, the cargo L is placed on the cargo platform 2 with the aircraft rolling rod 4, the cargo platform 2 is connected to the aircraft body through the fixed force rope 1, the main umbrella bag 3 is installed on the cargo L, and the cargo platform 2 is connected to the loading platform through the traction rope 5. The traction umbrella bag 7 that has traction umbrella 6 is connected, and traction umbrella bag 7 is connected with guide umbrella 8.

[0022] Then calculate the movement state of the traction parachute ...

Abstract

The invention belongs to the research on the airdrop method of a transport aircraft in the field of aeronautical aircraft design, in particular to aircraft traction airdrop system of a medium-sized transport aircraft and a method for determining airdrop parameters. At present, the airdrop mainly relies on helicopters, but there are some limitations such as small airdrop weight, small combat radiusand so on. The invention provides a traction airdrop system of a medium-sized transport aircraft and a method for determining airdrop parameters. According to the characteristics of the whole processof cargo movement in and out of the cabin, the tension characteristics of the pulling umbrella and the tension characteristics of the constant force rope in the process of straightening and spreadingthe parachute, by establishing the trajectory motion model of the towing parachute and the ground test on board, this paper sums up the process and implementation steps of the aircraft towed air drop, and then adjusts and perfects them according to the actual implementation of the flight test so as to fill the short board of the heavy-loaded air drop capacity, give full play to the cargo transport capacity of the transport aircraft, improve the economy and task efficiency of the transport aircraft, and meet the material transport needs of the whole army in peacetime and wartime.

Description

technical field [0001] The invention belongs to the research on a transport aircraft airdrop method in the field of aviation aircraft design, and in particular relates to a method for determining airdrop parameters of a medium-sized transport aircraft traction airdrop system. Background technique [0002] Medium-sized transport aircraft have a wide range of application prospects and social needs, and can be used to support the military's peacetime and wartime combat operations and logistics support and supply work, and to undertake emergency rescue and disaster relief missions in peacetime and other fields. [0003] At present, airdrops mainly rely on helicopters, but there are limitations such as small airdrop weight and small combat radius. According to the user's needs for the use of transport aircraft and the expansion of application fields, it is necessary to increase the air delivery capability on the basis of the conventional flight transportation profile of the mediu...
