AeroWindTunnel 6.0 ($100.00 US) New!
Airplane Flight Dynamics & Stability Analysis
for Gliding and Powered Flight
Detailed Information
Buy On-Line
AeroWindTunnel is AeroRocket's first wind tunnel simulation program for determining airplane and glider stability and whether or not a glider or model airplane is stable enough to fly. AeroWindTunnel is a true wind tunnel simulation program in that it determines whether an airplane is stable based on the position of the wing-body neutral point relative to the center of gravity and whether the relative contribution of the wings, fuselage and vertical fins to the forces and moments around the airplane center of gravity are sufficient for longitudinal and lateral stability. In addition, AeroWindTunnel uses slider-bar control to define airplane geometry instead of time-consuming CAD geometry definitions. AeroWindTunnel has been validated from 0.3 Mach to 3.5 Mach using the AeroRocket wind tunnel and other online sources.

Detailed Information
Nozzle Validation Analysis
Buy On-Line

Nozzle is a one-dimensional compressible flow computer program for the analysis of converging-diverging rocket nozzles. Nozzle internal flow may be entirely subsonic, entirely supersonic or a combination of subsonic and supersonic including shock waves in the diverging part of the nozzle. Shock waves are clearly identified as vertical red lines on all plots. The cross-sectional shape in the axial direction of the nozzle is specified by selecting from five standard nozzle types or by defining nozzle geometry using the Free-Form nozzle geometry method. Nozzle plots color contours of pressure ratio, temperature ratio, density ratio, and Mach number and has a slider bar that displays real-time values of all nozzle flow properties. New in this version is the ability to determine shock-angle, jet-angle (plume-angle) and Mach number for axisymmetric and two-dimensional nozzles in the region near the lip for underexpanded and overexpanded flow.

AeroDRAG & Flight Simulation ($35.00 US) New Version!
Aerodynamic Drag Prediction and Flight Performance Analysis
Detailed Information
Buy On-Line

AeroDRAG & Flight Simulation is a computer program that allows the rocketeer to quickly and easily perform rocket drag (Cd) and flight simulations using the power of Microsoft Windows. AeroDRAG & Flight Simulation interactively predicts subsonic, transonic and supersonic rocket drag to Mach 20 using the Newtonian surface inclination method for nose-body and fin combinations. AeroDRAG & Flight Simulation also performs flight simulations of rockets in vertical flight. For flight simulations the basic equations of rocket motion are repeatedly integrated to determine rocket velocity, altitude and acceleration using a finite difference procedure. In this latest version of AeroDRAG & Flight Simulation, the Cd can vary with rocket velocity and air density varies with altitude. The ability to model the variation of Cd with velocity (Mn) is important for accurate high speed and high altitude rocket predictions. Finally, AeroDRAG & Flight Simulation is unmatched in its ability to determine subsonic drag of ring-fin and tube-fin stabilized rockets along with many other new features. Now, AeroDRAG & Flight Simulation models the two-dimensional flight path of rockets that fly in the proximity of the gravitational field of the Earth.
