I have been trying hard to get something useful out of the Evolution software. Ailerons are almost full wing length, but split so that the inboard can be used solely as flaps to test the limits for low speed autolanding and autolaunch.įlight trials will start in the next few days.įor all those who were part of the discussions, here are some photos of the process and the results. The wings are CNC foam cut cores, vacuum bagged with Carbon cloth and mylars top and bottom. The 'New' wing is the S7075, chord 315mm, and span 2meters. Fitted to our SurVoyeur aircraft with an all up weight of 4.8kg ( a heavy camera.) we achieve around 35km flight range at 21m/s airspeed on two 4cell lipo packs, each 5000mAH. The 'original' wing is a Clark Z Aerofoil, 316mm Chord and 1.8meter span. Many Aerofoils were simulated and the S7075 choice seemed a good one, so I proceeded to make a prototype set of wings to begin some trials. A number of folk joined in with ideas and suggestions, and the choice was eventually made - The Selig S7075 at 9% thickness. Posted by Gisela & Joe Noci on Decemat 11:30amĪround 10 days ago I started a debate on wing Aerofoil choices to improve flight range rather than endurance.
