the bottom of the launching tube is communicated with the energy storage tank through a gas conveying pipe.
7. The distributed unmanned aerial vehicle platform applicable to ballistic launch of claim 1, wherein: the outer wall of the launching tube is provided with a launching tube handle.
8. The distributed unmanned aerial vehicle platform applicable to ballistic launch of claim 1, wherein: the distance between the two oppositely arranged mission machines is the same as the length of each mission machine wing after being unfolded.
9. A launching method of a distributed unmanned aerial vehicle platform applicable to ballistic launching based on any one of claims 1-8, characterized in that: the method specifically comprises the following steps:
firstly, before the flight platform body is launched, the whole structure is embedded in a launching tube, the bottom of the flight platform body is propped against a floating piston of the launching tube, and the top of the flight platform body is positioned through a following fixture of the launching tube;
in the second step, in the pressurizing stage, the energy storage tank releases large-volume compressed liquid or compressed gas into the launching tube through a gas transmission pipe so as to instantly pressurize the launching tube;
thirdly, in the launching stage, the compressed liquid or the compressed gas expands to push the launching floating piston in the launching tube to abut against the flying platform body to realize accelerated motion, the flying platform body pushes the launching tube to move along with the type clamp towards the tube opening until the flying platform body is thrown away from the tube opening of the launching tube, and at the moment, the launching tube impacts the braking device along with the type clamp;
fourthly, in a pressure relief stage, after the flight platform body is separated from the launching tube, starting a launching tube ejection control valve to relieve the pressure in the launching tube;
and fifthly, after the flying platform body reaches the preset height, the flying platform body is converted into flat flight, the escort machine transmits the carried resources to the mission machine, the connecting mechanism is unlocked, the flying platform body is separated, the escort machine returns and vertically descends, and the mission machine returns and vertically descends after completing the mission.
