The invention provides an unmanned load launching device which comprises a base internally provided with a launching cavity. The acceleration part is arranged in the emission cavity and moves along the emission cavity; the elastic deformation piece is arranged between the base and the acceleration part; the locking assembly is arranged in the launching cavity and locks or releases the acceleration part; the elastic deformation piece can be heated to generate elastic deformation and generate potential energy for pushing the acceleration part to move; the locking assembly releases the acceleration part when the potential energy accumulated by the elastic deformation piece reaches the maximum; the thermal shape memory performance and the superelasticity of the shape memory alloy are utilized, the elastic deformation piece is heated and cooled to deform or reset, potential energy accumulated during deformation of the elastic deformation piece provides emission power, the deformation capacity of the shape memory alloy cannot be greatly weakened along with time, and the shape memory alloy can be used for emitting power. Therefore, continuous and stable launching power can be provided.

    本发明提出了一种无人负载发射装置,包括基座,其内设置有发射腔;加速部,设置在发射腔内并沿发射腔移动;弹性形变件,设置在基座与加速部之间;锁定组件,设置在发射腔内并锁定或者放开加速部;其中,弹性形变件能够受热发生弹性形变并产生推动加速部移动的势能;锁定组件在弹性形变件积蓄势能达到最大时放开加速部;利用形状记忆合金具有的热形状记忆性能及超弹性性能,通过对弹性形变件进行加热和降温来使其发生形变或者复位,其形变时积蓄的势能提供发射动力,形状记忆合金的形变能力不会随时间发生较大的削弱,从而能够提供持续且稳定的发射动力。
