The dynamic mathematical model of thermodynamics on "human-cabin"has been presented by considering an intergral system of cabin and human.The physiological data used in the model were obtained from tests, and the empirical formulas used in the model were checked with tests.Based on the model, several thermophysiological indexes for the pilot in a cabin can be predicted and the cooling or heating capacity and the other parameters of an air conditioning system can be determined.As an example, the dynamic characteristics of the temperature within the cabin of a fighter in a typical flight profile and the thermophysiological indexes for the pilot set in it were predicted.The finite difference method was applied to computation of the transient temperature within a cabin, and the Roung-Kutta integration scheme was adopted in order to compute thermophysiological indexes of a body tinder varying environmental conditions.The computational results show that the mathematical model presented in this paper is satisfied.

The trajectory optimization techniques of aircraft vertical flight profile were studied in this paper.The point-mass energy state approximation model of aircraft motion was used as state equations,direct operating cost (DOC)as the index functin.The vertical flight profile was assumed to have three flight segments climb,cruise and descent.The energy state was taken into the index function,and became the independent or time-like variable in the Hamilton function.By using the dynamic variation method and the minimum value principle,the optimization algorithms for three segments were developed,and the Fibonacci search method was used to realize the optimization process.Finally,some digital simulation results for a Boeing-707 aircraft model were given in this paper.
