Embodiment Construction

[0060] The content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0061] 1. Summary of invention principle and invention method:

[0062] 1. The initial overload of the aircraft ejection is too large because the acceleration at the moment of initial ejection is too large, and the acceleration is proportional to the overload coefficient. There are two reasons for the excessive acceleration at the initial ejection moment. First, to make the aircraft generate sufficient departure velocity when it leaves the aircraft, sufficient acceleration must be used in the ejection process to generate sufficient departure velocity. The acceleration is called It is called "ejection acceleration"; secondly, the current three conventional power systems are all overloaded during the initial ejection, that is, the starting point acceleration is the largest, especially for rubber band catapults and rocket catapults, because the starting poi...

Abstract

The invention discloses a controllable two-stage-ejection vehicle-mounted control system of an unmanned aerial vehicle (UAV). The controllable two-stage-ejection vehicle-mounted control system comprises an ejection frame, an ejection vehicle, an ejection sliding rail, a controllable two-stage-ejection drive mechanism, a controllable two-stage-ejection vehicle-mounted control mechanism, an automatic opening frame and a UAV lock frame mechanism. The invention also discloses a control method of the controllable two-stage-ejection vehicle-mounted control system of the UAV. The control method comprises the steps of respectively generating high-pressure gas and low-pressure gas by an air compressor, sending the high-pressure gas and the low-pressure gas to a high-pressure gas container and a low-pressure gas container, activating first-stage movement of the ejection frame by the controllable two-stage-ejection vehicle-mounted control system while sending a time instruction for activating second-stage movement of the ejection frame to an ejection time relay and a time instruction for releasing an ejection lock fastener, and activating the second-stage movement of the ejection frame and releasing the ejection lock fastener by the ejection time relay. The controllable two-stage-ejection vehicle-mounted control system of the UAV realizes the reduction of initial ejection acceleration, soas to furthest avoid the problem of excessive initial overload during the ejection process and to meet the requirements of enough off-frame speed at the same time.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle ejection, and in particular relates to a vehicle-mounted control system and an ejection method for a controllable two-stage ejection of an unmanned aerial vehicle. Background technique [0002] All aircraft that adopt the fixed-wing method need to use the speed of the relative air to generate power to fly. So fixed-wing aircraft usually need to have enough runway to gain enough lift to lift off the ground and into the air when the aircraft reaches a certain speed. An aircraft that also utilizes speed to obtain aerodynamic lift also needs a runway of sufficient length when landing on the ground. Although many aircraft adopt multiple methods to reduce the landing speed to shorten the required runway length when landing, the landing runway cannot be cancelled. [0003] At present, the runway of aircraft can have various paving surfaces of different qualities. For the runway surface ...
