The transputer is a new single chip computer developed by INMOS corporation in recent years. It has been widely used for its high-performance，f1exibility and low price. In this paper，the solutions for simulation of an aeroplane's flight with six degrees of freedoom on various computers，such as transputer，YH-Fl，YH-l and etc.，are listed. The results show that the transputer multiprocessor systems are of high cost-performance，one order of magnitude higher than a mainframe computer.
