Description
Technical field
The utility model relates to a kind of hot load testing machine, particularly relates to a kind of for the hot load testing machine in weapon development hot test.
Background technology
Under tech war condition, the environmental suitability of weaponry has become the principal element affecting its q&r.Data show according to statistics, and the weapon product bug that environmental factor causes accounts for about 50% of total failare, wherein temperature factor account for that environmental factor causes fault 40%.Therefore, hot test as a kind of reproduce weaponry in length of life experience the simulation means of hot environment, be obtain weapon related data, evaluate hot environment to one of important means of the security of weaponry, integrality and performance.
In the hot test that the outer weapon development production unit of Present Domestic is carried out for the inspection weapon quality of production, mostly select sweat box to carry out heat loading and environment is simulated.This hot load mode of sweat box is placed in chamber by weapon product, utilizes air themperature in heat test case with simulated weapons environment for use, finally make weapon response temperature reach stable.According to domestic and international hot test standard as GJB150A, American army mark MIL-STD-810D/E/F etc., this test method can meet the environmental suitability examination of weapon product constant temperature or slow linear varying temperature environment.But, due to weapon technologies progress, there is the new weapon such as Hypersonic Weapon or space weapon.The environment for use of these weapons has that heating rate is fast, temperature rise high.Such as Hypersonic Weapon passes near space with the speed of flight Mach number 5, even if the provision for thermal insulations such as ablation layer taked by weapon, its shell response temperature also can reach a few Baidu, response temperature rise rate is more than 10 DEG C/min, to this hot loading simulation fast, under hot environment, conventional temperature case can not be suitable for.
Temperature control object aspect: traditional sweat box heated for controlling temperature to as if sweat box in air, think that, after long temperature stabilization, product response temperature can reach balance, this way is effective and necessary to long-time product examination of placing.But weapon product length of life also should comprise transmitting, flight equitemperature changes occasion faster, these occasions often temperature are high especially, temperature rise rate is fast especially, air and aircraft surface direct friction cause temperature to raise fast, therefore the heat of this course loads the response temperature should paying close attention to test products, and traditional experiment case is really not so.
