Can anybody shed some light on the accuracy of the airflow around the fuselage on the attached image? The wing is based on the GM15 foil. Rest of the details is in the picture. The modeling was done with XFLR5.Does the results of lift, drag etc look credible?
However, perhaps everyone will be interested to note that an Open Source Airframe has just been released by the OpenRelief project.
Here is an overview of the specs: * Length 1.4 meters * Wing span 1.8 meters * Chord 30cm * Uses counter-rotating motors (redundancy, speed, balance, no torque) * Uses remote servos (wing flaperons, the tail surface) for more storage and ease of repair * Empty weight 3kg * Thrust is 12kgs * Max load 12kg (lift at 100mph/160kph is approx 12kg) * Endurance is between 1 to 4 hours with existing specifications * Wings can be repositioned to change CoG for large payloads * Stringers located on the fuselage to carry the wing, landing gear and other items (modules) * These channels also hold internal items like the motor via bulkhead rings, for quick changes * Fuselage can carry liquids (same diameter as 2L bottle of cola) * Can be launched by rail and use parachute recovery * Can be fitted with front wheels for conventional landing in rough fields
Hello wayne,
I have a small knowledge in Airplane Aerodynamics but willing to improve it !!
Could you please give some details or explanations about your comment ?

It looks like this project has stalled (also in another thread: http://diydrones.com/forum/topics/open-source-uav-airframe?xg_sourc...).
