Abstract

The invention discloses a controllable air-drop parachute, which comprises a drogue parachute, a main parachute, a control rope, a balancing pole, an execution motor, a measurement and control system and a suspender, wherein the main parachute is connected with the control rope; the control rope is connected to the execution motor through the balancing pole; an output end of the execution motor is connected with the control rope; an input end of the execution motor is connected with an output end of the measurement and control system; and an input signal of the measurement and control system is given by the balancing pole and a positioning system. The controllable air-drop parachute has the advantages of compact and simple structure, high universality, high practicability and low cost; an unmanned automatic device is additionally arranged on the basis of the conventional parachute for reconstruction; air-drop efficiency of supplies can be greatly increased; and various unnecessary losses and the like are avoided.

Description

Parachute is used in a kind of controllable type air-drop

Technical field

The invention belongs to parachute, particularly can be used for being responsible for the guided parachute of air-dropped material under the environment.

Background technology

In contemporary society's life, it is social activities and the requisite task of development that goods and materials transport.Because the influence of many objective factors, some can't carry out under the situation that goods and materials transport in a usual manner, and (like disaster, war factor influence etc.) air-drop is technological to become a kind of special means; Conventional air-drop technology receives the influence (like wind-force disturbance, complicated landforms influence etc.) of a lot of physical conditions can't send to the appointed place accurately with the air-drop thing, the economic loss that causes thus (as avoid goods and materials repeatedly repeat throw in) and unknown losses (can increase the successful property of the disaster relief) as in time sending to goods and materials in the disaster relief task quite serious.So, significant meaning is arranged for accurate air-drop Study on Technology.

Summary of the invention

To the objective of the invention is the problem that exists in the conventional air-drop means in order solving, the technique device that can improve air-drop efficient, avoid a kind of accurate air-drop of economic loss and unknown losses to be provided.

The technical scheme that adopts is:

Parachute is used in a kind of controllable type air-drop; Comprise pilot-parachute, main chute, tricing line, trammel beam, actuating motor, TT&C system and suspension composition; Main chute is connected with tricing line, and tricing line is connected to actuating motor through trammel beam, and the actuating motor mouth connects tricing line; The actuating motor input end connects the TT&C system mouth, and the TT&C system incoming signal is provided by trammel beam and position fixing system.

Advantage of the present invention is: compact conformation, simple, and highly versatile, applicability is high; Cost is low; Can on existing conventional parachute basis, install the repacking of unmanned operatorless device additional, can increase substantially cargo assault efficient, avoid unnecessary various losses and loss etc.

Description of drawings

Fig. 1 is a principle schematic of the present invention.

Among the figure: 1 pilot-parachute, 2 main chutes, 3 tricing line, 4 trammel beams, 5 actuating motors, 6 TT&C systems, 7 suspensions.

The specific embodiment

As shown in Figure 1, parachute is used in a kind of controllable type air-drop, comprises pilot-parachute 1, main chute 2, tricing line 3, trammel beam 4, actuating motor 5, TT&C system 6, suspension 7.Main chute 2 is connected with tricing line 3, and the logical 3 overbalance bars 4 of tricing line are connected to actuating motor 5, and actuating motor 5 mouths connect tricing line 3, and actuating motor 5 input ends connect TT&C system 6 mouths, and TT&C system 6 incoming signals are provided by trammel beam 4 and position fixing system.

A kind of controllable type drops the principle of work with parachute: vacate at the height of suitable height missile is dished out; Initial condition with release position is input in the TT&C system simultaneously; Pilot-parachute 1 at given height parachute is opened; Through pulling of pilot-parachute 1 main chute 2 is opened, treated that main chute 2 opens back actuating motor 5 fully and start working, the parameter that provides through TT&C system applies the sense of motion that pulls with the control parachute to tricing line 3; TT&C system is analyzed the motion of parachute according to the kinematic parameter of positional parameter and parachute itself; And provide control signal corresponding, with this input, make that parachute can be constantly near the predetermined object point of throwing in as actuating motor 5.

Claims

1. parachute is used in a controllable type air-drop; Comprise pilot-parachute, main chute, tricing line, trammel beam, actuating motor, TT&C system and suspension composition; It is characterized in that: main chute is connected with tricing line, and tricing line is connected to actuating motor through trammel beam, and the actuating motor mouth connects tricing line; The actuating motor input end connects the TT&C system mouth, and the TT&C system incoming signal is provided by trammel beam and position fixing system.
