This project focuses on the reduction of noise and wall heat transfer of afterburners. For this project, the JetCat P250-PRO micro jet turbine was chosen due to its low cost and professional performance characteristics. First, the design for an afterburner to fit the mentioned turbine will be made with various interchangeable low bypass cooling shrouds to test the shrouds effectiveness in noise reduction and heat flow properties. Noise reduction was chosen as the primary research focus because of noise levels of aircraft, especially during takeoff with afterburners, is a serious problem. The secondary focus of heat flow was chosen due to the limiting factor of a lifetime for afterburners is heat. Reducing the heat signature is also a valuable topic, especially for military jet aircraft. Once designs for an afterburner have been chosen, the JetCat P250-PRO will be purchased, and the afterburner sent for manufacturing. Static bench testing will be performed to simulate take-off conditions to evaluate noise reduction and heat flow of each low bypass cooling shroud design
