Problems solved by technology

This method is very sensitive to the resonance generated by vibration and the weight change of the device. The weak current change in the oscillator, the fluctuation of the jet pressure, and the inevitable change in the weight of the device as the particles are broadcast will affect its stability.

Abstract

A high-performance mechanical particle distributor for uniformly distributing the particles into high-temp heat flow generated by the spray tube of arc heater at a certain mass flow rate is composed of cylindrical material cabin, container outside said cylindrical cabin, central screw bolt in said cylindrical cabin and linked with its bottom via bearing, and a spiral discharging unit at the outlet of cabin.

Description

(1) Technical field [0001] The invention relates to a mechanical particle distributing device for uniformly distributing particles into the high-temperature heat flow provided by an arc heater nozzle at a certain mass flow rate. (2) Background technology [0002] When a reentry vehicle enters the atmosphere, it will face harsh environmental challenges. The aerodynamic heating caused by the high-speed incoming flow will cause the temperature of the aircraft head to rise suddenly and cause the material to ablate and retreat. On the other hand, when the aircraft re-enters the atmosphere, it will also encounter particle clouds produced by nature or man-made. Particle cloud components include water vapor condensate particles such as water droplets, ice crystals, and snowflakes, and dust suspended in the atmosphere. Since the reentry speed of the aircraft is very high, usually reaching tens of Machs, particle erosion will have a very serious impact on the retreat and shape stabil...
