Abstract
A novel first stage compression system for the TUSQ facility is proposed which works under the principle of free piston compression. This principle is used to compress air isentropically and feed it into the primary stage of compression which can generate flows to simulate hypersonic flight conditions. A PVC pipe with pressure rating 1.2 MPa and length 6 m and diameter 0.25 m is used for the compression process. The proposed facility uses atmospheric pressure as a source to propel the piston. A numerical analysis is performed on Matlab which uses Euler’s method, Isentropic relations and Newton’s second law of motion to understand the piston dynamics. The Euler’s method predicts the position and the velocity of the piston. From the numerical analysis, the optimum mass of the piston and initially filled pressures are predicted to be in the range of 0.3 kg to 0.6 kg and 20 kPa to 30 kPa respectively. The velocity and the position predicted using Euler’s method is 282 m/s and 5.5 m respectively. The overall pressure obtained is 680 kPa. A virtual prototype of the first stage compression system is modeled using Creo Parametric 3.0. An FEA Stress Analysis is carried out using Creo Parametric 3.0 to determine the viability of the proposed PVC reducer plate and the pipe support system. The Von Mises stress is calculated using FEA analysis for the pipe support and the PVC reducer plate is 2.55 MPa and 4.89 MPa respectively.
