Planning
The model is sized by scaling concerning the fan diameter for a more realistic look. Simple calculations are made to check the practicality of the plan with the estimated weight of the airframe.
XFLR5 is used to make sure that the aircraft is statically stable at different configurations. The drag coefficient provided by the software is not accurate, but having a reference in the early stage is important. The sizing and positioning of the spoilers utilized the transition location from a 2D simulation to take advantage of the added control surface.
Modeling
Modeling
3DExperience CATIA is used to make the 3D model of this model. Because the size of this model is small, and the weight is minor, it is fine to land on grass without landing gear.
The saved weight and lowered wing loading are also desirable.
Production Plan
Production Plan
The solid model is designed to be printed as the molds for vacuum forming and composite fabrication. For example, the canopy needs to be vacuum-formed with PVC sheets, and the cowlings need to be heated and formed with Depron foam. The wing and fuselage will be a combination of glass fiber shells, carbon fiber reinforcement panels, and Aramid strands for tensile strength.
