Embodiment 1
[0032] figure 2 It is the schematic diagram of the helicopter brake start control circuit, combined with figure 2 As shown, the helicopter braking and starting control circuit of the present embodiment 1 includes an engine electronic controller circuit, a helicopter power supply, a first switch, a second switch, a brake interlock circuit and an engine starter,
[0033] The helicopter power supply, the first switch, the second switch and the engine starter are sequentially connected in series; the brake interlock circuit controls the on-off of the first switch;
[0034] The engine electronic controller circuit includes an engine electronic controller and a starting relay, the engine electronic controller is electrically connected to the starting relay, and controls the operation of the starting relay, and the starting relay controls the on-off of the second switch;
[0035] When both the first switch and the second switch are closed, the engine starter works.

Embodiment 2
[0039] figure 1 The schematic diagram of the rotor brake starting system is combined with figure 1 and figure 2 Shown, a kind of helicopter brake start system, described brake start system comprises brake start control circuit,
[0040] The rotor brake annunciator is signal-connected to the engine electronic controller, and is used to feed back to the engine electronic controller whether the brake stop mechanism has stopped the helicopter rotor;
[0041] After the engine electronic controller receives the start signal, the brake interlock circuit and the engine electronic controller circuit respectively control the on-off of the first switch and the second switch to control the engine starter Starting: the engine electronic controller controls the starting mode and working state of the engine according to the signal fed back by the rotor brake device.
[0042] Further, the starting mode includes a first starting mode and a second starting mode,
[0043] The first start mo...
