Rc Aircraft - Wing - Build log
The whole exercise of design, construction/build and trimming of a Flying Wing. Requirements Wanted an aircraft which could fly long in a calm (thermal) or on slopes (windy)… . Structurally wanted maximum use of locally and easily available material. Should be easily transportable. Easy to build.. span around 48” to 50”. It would be hot wired EPS(thermocole) covered with paper. This keeps the weight down and gives a good airfoil adherence. Planform • Opted for a flying wing on basis of wing loading and less drag, and the fact that I would not have to construct a fuselage. Balsa with covering was out of scope. Reynold number is estimated would be around/below 100000 Construction method • Hot wired EPS(thermocole) covered with paper . This keeps the weight down and gives a good airfoil adherence. Design • Did not want to go with an plank design primarily due to pitch response issues with a high aspect ratio in a...
