Stringent emission rules, air pollution, fluctuation of fuel price and depletion of fossil fuel resources are driving the industry to seek for better alternative of power generation. Micro gas turbine (MGT) provides a promising potential to solve the facing problems. MGT could be used in many applications such as in range extender vehicle, auxiliary power generator, power backup system, combine heat and power system, etc. Combustor plays a very crucial role in MGT system as its performance directly affects the emission quality, power output and fuel consumption of the entire system. This paper demonstrates the literature review, design methodology and performance prediction of the combustor designed for a 14.5kW MGT test rig.

Nuclear Power Generator

According to the working conditions of the nuclear power generator slot wedge and the principle of the heat treatment, CuCo2BeZr copper alloy was strengthened by a series of heating process test, finally acquired a good performance of the nuclear power slot wedge. The results show that, after the process of hot extrusion deformation of 85.5% and solution treatment at (940±10 )°C for 2h, then aging at 540 °C for 4h, the composition, microstructure, fracture morphology and tensile properties of CuCo2BeZr copper alloy, as the material of nuclear power generator, could meet the conditions of working continuously in high temperature enviroment.The research of CuCo2BeZr copper alloy provide scientific basis for analyzing the inner mechanism of the failure and predicting the working life of the nuclear power slot wedge material.

This paper focuses on the calculation of modal frequencies and corresponding mode shapes of Gun Barrel by analytical method and the Finite Elements Method. Modal analysis is used to find out natural and succeeding two modes frequencies for transverse vibration. Barrel is considered as a cantilever beam. Recoil of Gun Barrel is incorporated as variation in the length cantilever beam. Increase in modal frequencies due to gun barrel recoil is observed. It is concluded that the transverse vibration of gun barrel coupled with the recoil produces a band of frequencies in each modes. The analysis and results discussed can be used for design and performance evaluation, selection of accessories and attachments of gun systems.
