Direct cycle control drum type nuclear power engine

Abstract

The invention provides a direct cycle control drum type nuclear power engine. The direct cycle control drum type nuclear power engine comprises a reactor core reflecting layer, a control drum system, a radiation shielding body, a pressure vessel, a reactor core, a blade-adjustable compressor, a blade-adjustable turbine, a stationary cascade, a diffuser and a tail nozzle, wherein the reactor core, the blade-adjustable compressor, the blade-adjustable turbine, the stationary cascade, the diffuser and the tail nozzle are mounted in the pressure vessel; the control drum system comprises eight groups of control rotary drum elements, each group of control rotary drum elements is composed of a neutron absorber, a rotary drum driving mechanism and a rotary drum channel, the rotary drum channel provides an accommodating space and a rotating space for the neutron absorber, and the whole control rotary drum system is uniformly arranged in the reactor core reflecting layer at the same interval; the direct circulation control drum type nuclear power engine is long in endurance, large in thrust, safe and reliable, the device is provided with the adjustable compressor and turbine blades, the device can adapt to different space heights, and the problems that a traditional aircraft engine cannot utilize the near space and the endurance mileage is limited can be solved.

Description

technical field [0001] The invention relates to the fields of nuclear reactor engineering technology and power device design, and in particular relates to a nuclear power engine device. Background technique [0002] Nuclear fission is the process in which a heavy nucleus absorbs a neutron and splits into two lighter nuclei. On the one hand, each nuclear fission releases a large amount of energy that can be used, on the other hand, it produces new neutrons, and the newly produced neutrons continue to cause more nuclear fissions of heavy atoms, so that continuous development forms a "chain fission reaction", thus Continuously release a lot of energy. In the process of nuclear fission, by making the number of neutrons bombarded on the nucleus of the previous generation and the number of neutrons bombarded on the nucleus of the next generation basically equal, a critical state can be reached, and the nuclear energy released by nuclear fission is basically stable , can be fully...
