| Abstract: | Based on test data and temperature rising principle of altitude test facility,the factors influencing temperature rise process are analyzed,finding that the temperature at the outlet of the mixer is the key factor affecting temperature rise rate.At the same time,adopting the method of building mathematic model based on test data,the empirical value is translated into mathematic model,realizing the simulation of temperature rise process of altitude test facility. |
