Hence they must be made strong enough to withstand the aerodynamic stresses. This range allows for very less unpowered gliding but since the aircraft was not intended to function as a glider, this is satisfactory. The plane should undergo level flight at less than 5 degree angle of attack. This would prevent the plane from flipping under high aerodynamic loads.

Control surface stalls and full plane stalls were also visualized. Lift, Drag, Pitching Moment, Movement of center of pressure, and Flow visualization for different angles of attack and different deflections of control surfaces. The flow visualization of streamlines and pressure gradients was obtained for specific cases where they may be noteworthy of interest. Also keep in mind that these simulations are only for our own gratification. Note that a good RC plane can be made following simple thumb rules which may be found on any good sites like flitetest. FT-22 Raptor Speed Build Kitīeing aerospace engineering students, we thought of simulating and refining our model. Because, Why Not? Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The design considerations suggested a preliminary design that came out to look a lot like the F Raptor, so we decided to build a similar one and performed a few simulations on it with ANSYS. Coroplast would be a better build material as it was easier to cut and paste together and gave good strength perpendicular to the braided direction. We built our previous planes using balsa wood which took a lot of time to build and were difficult to repair when crashed. This comes with a reduction in the number of control surfaces and required servos.

Thus it should be designed for neutral stability with zero camber flat-plate airfoil. In our first year we had made a few Trainer RC Airplanes, but due to poor piloting skills, had experienced a number of nose-down crashesbreaking quite a few propellers and even a motor. Our team consists of aero-modelling enthusiasts currently enrolled in an undergraduate degree in Aerospace Engineering. The USAF considers the F critical to its tactical air power, and says that the aircraft is unmatched by any known or projected fighter. It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The Raptor's combination of stealth, aerodynamic performance, and situational awareness gives the aircraft unprecedented air combat capabilities. The aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities.
