摘要： An electromagnetic induction type Hopkinson pressure/tension bar loading device and experiment method therefor. A positive electrode output line of the output of a capacitive charger is connected with a positive electrode line of a loading gun, and a negative electrode output line of the output of a capacitive charger is connected with a negative electrode line of the loading gun. The present invention not only can generate compression stress waves but also can generate tension stress waves through the electromagnetic induction principle, and is applied to the loading of a Hopkinson tension bar and a pressure bar. Thus, the loading systems for a Hopkinson tension bar and a pressure bar can simultaneously achieve the strain rate and strain range, which the traditional split Hopkinson bar experiment cannot reach, on the same device, so that the Hopkinson bar experiment technology is standardized, and the experiment devices for a tension bar and a pressure bar are integrated, thereby reducing complexity and floor space of equipment.

摘要： The present invention discloses a distributed propulsion system. An input end of a gas collecting device of a high-energy working medium collecting device is communicated with an output end of a core engine compressor of a turbine engine core engine; and an output end of the high-energy working medium collecting device is communicated with an inlet of the high-efficiency working medium transporting device. An output end of a transporting branch pipe in the high-efficiency working medium transporting device is respectively communicated with an input end of a propulsor turbine volute of each distributed propulsor; and an input end of the transporting branch pipe is communicated with a transporting header pipe in the high-efficiency working medium transporting device; and multiple distributed propulsors are evenly distributed on both sides of the turbine engine core engine. The present invention overcomes the dependence of the electric power distribution-based distributed propulsion system on a high-energy density energy storage device and an ultra-high-power motor, thereby improving the achievability of the distributed propulsion system and simultaneously getting rid of the mechanical constraints between a gas generator and the propulsors in a mechanical transmission-based distributed propulsion system, breaking through the limitation of the bypass ratio of a turbofan engine to the traditional distributed propulsion, realizing the heat regenerating design and improving the propulsion efficiency.
