Temperature Response of a Model to Set-Point Changes and Conditioning in Etw

摘要

Preliminary finite element thermal analysis of a model balance sting arrangement mounted in a cryogenic wind tunnel concluded that heated balances were unacceptable if the model surface temperature was to satisfy the 1% adiabatic wall temperature condition specified by Green. The results of a more detailed finite element thermal analysis on an assumed 0.6 meter long stainless steel delta wing model supported by an unheated balance sting arrangement and subjected to the ETW set-point changes and temperature conditioning specified are summarized.
