Background technique
In the small-sized fixed-wing unmanned planes of the overwhelming majority of field work due to being limited by working space, there do not have to be suitable
It is sliding to run landing environment, generally use the operation mode of " catapult-assisted take-off+parachuting recycling ".Unmanned plane is frequently necessary in severe meteorology
Under the conditions of execute aerial mission, unmanned aircraft parachute descent landing after, if parachute cannot be separated with body in time, once incident
Undoubtedly catastrophic for unmanned plane body when encountering strong wind (v ≮ 6m/s), unmanned plane will be in the dragging of recorery parachute
Lower draw with ground is rubbed.Due to the complicated topographical conditions such as sandstone, gully, depression, wetland, steep cliff etc. of unmanned plane operating area,
It is easy to cause during towing unmanned plane body surface large area to scratch, components are broken, fall off, even enter water causes airborne set
The secondary damages such as the destruction of standby unrepairable, the maintenance support pressure and flight operating room for considerably increasing unmanned plane are every seriously
Constrain the efficiency that unmanned plane executes aerial mission.
It is in the prior art to cut umbrella technology, exist and cuts the triggering of umbrella signal inaccurately, the hidden danger of aerial false triggering;Control logic
It is complicated;The problem of control instruction dependent on flight control computer exports.
To solve the above-mentioned problems, the present invention provides a kind of unmanned planes to cut umbrella control system automatically, can accomplish
It after unmanned plane drops to ground, separates parachute with unmanned plane body automatically, is effectively reduced needs in bad weather condition
The secondary damage of the lower unmanned plane for carrying out parachuting recycling operation.
