摘要
塞块式瞬态量热计是气动加热地面模拟试验模型中表面冷壁热流主要测量手段之一,对塞块式瞬态量热计测试结果进行了误差分析,并采用有限差分原理,建立了数学分析模型,编制了瞬态量热计测量结果修正计算程序,并对一些典型的测试结果进行了修正和分析。
The transient plug type heat fluxmeter is one way of the measurement for cooling wall heat flux in the aero thermal heating ground simulation test. The error analysies for the result of transient plug type heat fluxmeter are presented. The finite difference principle is used to establish a mathematical model, and then, a FORTRAN program is making to calibrate the measurement result, some test results are calibrated.
