Abstract

The invention discloses a novel roll booster ignition circuit. In the novel roll booster ignition circuit, a launch condition meeting relay is respectively connected with a roll booster ignition relay and one end of a launch allowing switch; the roll booster ignition relay and the other end of the launch allowing switch are respectively connected with a launch allowing relay; the launch allowing relay is connected with a roll booster; an ignition direction circuit comprises a detection pint, an ignition circuit detection relay and a detection circuit; the ignition circuit detection relay is respectively connected with the launch condition meeting relay, a launch condition allowing relay and the roll booster ignition relay; the front ends of the launch condition meeting relay and the roll booster ignition relay are provided with detection points. According to the novel roll booster ignition circuit, the output of the detection pints can be read by controlling the on and off operation of the ignition circuit detection relay, potential safety hazards are effectively eliminated, and the fight indexes can be met wholly.

Description

technical field

[0001] The invention relates to the technical field of aircraft booster ignition, in particular to a booster ignition circuit. Background technique

[0002] When the aircraft is launched on the ground, it is generally necessary to use the booster to obtain the initial speed of the aircraft. At the same time, in order to ensure the safe and reliable launch of the aircraft, the launch control system of the aircraft needs to accurately control the ignition of the booster. Therefore, the booster is required in the actual launch. The ignition circuit has high safety. At present, the booster ignition mode is relatively simple and the safety is poor. Usually, the launch button is connected in series to the main line of the ignition circuit, and is realized by simple relay logic; The distance is as high as 130m. Even if a 4mm2 wire is used, the minimum ignition current of the booster cannot be satisfied through theoretical calculations. Just by increasing the cross-...
