Stallion 3D uses your CAD design to simulate the performance of your aircraft. This enables you to verify your design and compute quantities such as cruise speed, power required and range at a given cruise altitude. Stallion 3D is used to optimize the design before moving forward with building and testing prototypes.
The table below shows the results of Stallion 3D around the cruise angles of attack of the Cessna 402c aircraft. The CAD design can be obtained from the OpenVSP hangar.
The results were obtained by simulating 5 angles of attack in Stallion 3D on an ordinary laptop computer running MS Windows 10 . Given the aircraft geometry and flight conditions, Stallion 3D computed the CL, CD, L/D and other aerodynamic quantities. With this accurate aerodynamics results, the preliminary performance data such as cruise speed, power, range and endurance can be obtained.
Lift Coefficient versus Angle of Attack computed with Stallion 3D
Lift to Drag Ratio versus True Airspeed at 10,000 feet
Power Required versus True Airspeed at 10,000 feet
The Stallion 3D results shows good agreement with the published data for the Cessna 402. For example, the cruse speed of the aircraft at 10,000 feet is around 140 knots. This coincides with the speed at the maximum L/D (best range) shown in the graph and table above.
