Abstract

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.
