FLUIDIC INJECTION THRUST REVERSER SYSTEM FOR HIGH BYPASS RATIO TURBOFAN ENGINES: EXPERIMENTAL MODEL

摘要

Conventional thrust reversers involve the usage of mechanical blockers which are bulky as they are designed to sustain heavy loads. As a result, they account for 30% of the nacelle weight (excluding the engine core). This added engine weight results in a 0.5%-1% increase in the specific fuel consumption of the aircraft. This paper advances our investigation of "Blockerless Engine Thrust Reversers " and uses it as an inspiration to optimize the system by designing an injection module (depicting an injection as a bleed from the core flow), conducting a computational analysis and demonstrating the viability of the process by building an experimental model of a 1:40 scale of a GE90- 115B engine. A 3D printed experimental model was built after conducting an extensive parametric analysis. This model is used to demonstrate the viability of the "Fluidic Injection Thrust Reverser" (FITR) qualitatively and quantitatively.
