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.

Virtual Maintenance

Trade-offs studies on two kinds of existing engine thrust reverser design were carried out, applying virtual maintenance method and the basic theory of ergonomics. Analysis on the maintainability of the two kinds of configurations, the O-duct thrust reverser owning the integrated propulsion system (IPS) and the traditional portal D-duct thrust reverser, were compared. According to the differences of O-duct and D-duct thrust reverser in the structure, working principle and mode of motion during the maintenance, structure modelling and kinematics simulation of two kinds of thrust reverser were finished in the same space constraints. Taking DELMIA software as the platform, the partial ergonomic research and evaluation including accessibility analysis, visibility analysis, specific disassembling and assembling time estimation and workspace analysis were put forward through the virtual maintenance simulation of two civil engine thrust reversers. Supplied technical reserves on design and selection, scheme analysis and technical evaluations for domestic engine thrust reverser in the future.

This work focuses on structural modeling and analysis of aircraft winglet control surfaces. In aerodynamic engineering, reducing drag is an important challenge. To reduce drag a fin device that is placed vertically in the angle set in the wing of the plane. Winglet design reduces fuel consumption by reducing the drag of the aircraft and will make the aircraft more stable during the flight, will also give the aircraft engine more time to reduce the load on the engine thrust life. The goal is to design and simulate a winglet aircraft model using software such as CATIA V5-which is used to build fin models and ANSYS CFX solver is used to test and simulate model fins. With winglets without fins it analyzes change the inclination angles, the results are compared and plotted. Fins are an important part of an aircraft that reduces the amount of drag and fuel consumption by using less energy while reducing wing vortexes.
