| Abstract Scope |
The exhaust system geometry of jet turbine engines exerts a significant influence on thrust generation, specific fuel consumption, and acoustic emissions. The manufacturing challenges of the exhaust system with complex geometry might be mitigated by using additive manufacturing (AM) techniques. The purpose of this research is to investigate the influence of different exhaust systems on the TJT-3000 micro jet turbo engine thrust. The exhaust components were manufactured by laser powder bed fusion (L-PBF) of Cu-Ni-Sn alloy powders. Geometric optimization of the exhaust nozzle was based on previous research findings and Computational Fluid Dynamics (CFD) simulations. The parts were printed in an EOS M 290 system operated at a laser power of 390 W under inert argon atmosphere. Post-printing annealing heat treatment was applied to the parts to enhance their mechanical properties. The results underscore the viability of AM for producing optimized exhaust systems for future jet propulsion applications. |
