Abstract

The invention discloses a combined asynchronous induction electromagnetic coil emitter and an ignition method thereof. The combined asynchronous induction electromagnetic coil emitter comprises a plurality of sets of multistage coil emitters, a gun barrel and a plurality of connectors. Each multistage coil emitter comprises a multistage driving coil set and a corresponding armature, the multistagedriving coils are sequentially wound outside the gun barrel in the axial direction of the gun barrel, the armatures are sequentially arranged in the gun barrel in the axial direction of the gun barrel, and the adjacent armatures are connected through the connectors. When the combined asynchronous induction electromagnetic coil emitter is not triggered, the armatures are located in the corresponding multistage driving coil sets. After the combined asynchronous induction electromagnetic coil emitter is triggered, the multistage driving coils provide acting force pointing to a gun opening in theaxial direction of the gun barrel for the armatures in the multistage driving coils. According to the combined asynchronous induction electromagnetic coil emitter, propulsive force of different pulsewidths, amplitudes and waveforms can be achieved, the accelerated speed faults of the armatures can be avoided, and therefore acceleration is smoother; meanwhile, stress, the emitting speed and emitting efficiency can be improved; and the combined asynchronous induction electromagnetic coil emitter is more suitable for occasions with higher requirements for thrust precision.

Description

technical field [0001] The invention relates to the technical field of launching large-mass objects such as missiles, in particular to a combined asynchronous induction electromagnetic coil launcher and an ignition method thereof. Background technique [0002] Since the velocity of the traveling wave of the magnetic field required for the acceleration of the projectile is higher and higher, the whole coil should be divided into several sections. In order to obtain traveling waves whose phase speed increases from one section to another, the frequency of the excitation power supply should be increased, or the polar distance (half wavelength) of the driving coil should be increased. The size of the pole pitch is determined by the number of phases, the length of the single-stage drive coil and the distance between the single-stage drive coils. The smaller the pole distance, the smoother the acceleration of the projectile and the greater the acceleration force. However, if the ...
