Abstract

The invention provides a hypersonic flight vehicle 250 DEG C per-second high-speed heat shock testing device and method. The hypersonic flight vehicle 250 DEG C per-second high-speed heat shock testing device mainly comprises a quartz lamp heating tube, a high-temperature testing piece, a run-through water cooling channel, ceramic heat-proof stop plates, a high-temperature-resistant ceramic reflection plate, K-type temperature thermocouples, a computer, a driving power source and a boosting transformer. The hypersonic flight vehicle 250 DEG C per-second high-speed heat shock testing method is a rapid high-accuracy potential-voltage conversion method of the temperature thermocouples when a heat shock environment is generated. According to the hypersonic flight vehicle 250 DEG C per-second high-speed heat shock testing device and method, a hypersonic flight vehicle 250 DEG C per-second extremely-high-speed nonlinear heat shock test can be achieved, and an effective high-temperature pneumatic heat test simulating mean is provided for developing a hypersonic guided missile at the higher flight speed.

Description

technical field [0001] The invention relates to the technical field of hypersonic aircraft extreme thermal environment test, in particular to a hypersonic aircraft 250°C / s high-speed thermal shock test device and method, especially when reproducing the aerodynamic heating environment of a hypersonic aircraft, it can simulate a temperature up to 250°C The extremely high-speed dynamic thermal shock process per second provides an indispensable ground thermal test method for the development of hypersonic aerospace vehicles or high Mach number missiles. Background technique [0002] With the substantial increase in the speed of current aircraft designs, the high temperature thermal environment generated by aerodynamic heating has become extremely harsh. The high temperature generated by severe aerodynamic heating during high Mach number flight will significantly reduce the strength limit of the hypersonic vehicle material and the load-carrying capacity of the structure, and serio...
