Entomopter Wing Analysis Boon for Mars Mission
Abstract
In this chapter, CFD analysis is performed to understand the aerodynamic characteristics of 3-D Entomopter wing. Entomopter is the MAV which is especially designed for Martian atmosphere exploration. It is a low Reynolds number flyer due to which it can reach to the places where human intervention is not at all possible. The aerodynamic simulations are carried out at different flap angles varying from -20º to 30º in Martian atmosphere. The Entomopter model considered for CFD analysis has a wingspan of 15 cm with varying chord length and Reynolds number ranging from Re=75000 Re=150000 i.e., at a velocity of 2 m/s to 30 m/s. The Entomopter 3-D printed model is designed in CATIA V5 and simulation is carried out using ICEM CFD and ANSYS FLUENT. Entomopters may undertake multimode operations and produce lift by continuously forming and shedding vortices from their flapping wings. So, this research is a viable aspect to understand the future development of MAVs for outer space exploration and can be promising for making impossible things possible.
