AeroRocket specializes in subsonic, supersonic and hypersonic aerodynamics, Computational Fluid Dynamics (CFD), warp drive physics and aerospace related software development for rockets, airplanes and gliders. Other services include wind tunnel testing using the AeroRocket designed and fabricated subsonic wind tunnel and supersonic blow-down wind tunnels.

AeroCFD® is a registered trademark of John Cipolla and is classified as an axisymmetric 3-D and planar 2-D Computational Fluid Dynamics (CFD) computer program. However, AeroCFD solutions are not limited to bodies of revolution even though AeroCFD's bodies of revolution can be very complex.

Nozzle 10: One-dimensional and two-dimensional, compressible flow computer program for the analysis of converging-diverging nozzles, including ramjet and scramjet engines. Nozzle models inviscid, adiabatic and hence isentropic flow of a calorically perfect gas through variable-area ducts. 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. Nozzle 3.7™ Copyright © John CipollaThe 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. The converging-diverging nozzle featured in the new AeroRocket supersonic blow-down wind tunnel was designed using Nozzle applying the concept of a normal shock diffuser. More ...

HyperCFD 10
: Supersonic and hypersonic re-entry vehicle and rocket analysis computer program based on advanced principals of 3-D Gasdynamics. HyperCFD, determines drag coefficient (Cd), center of pressure (Xcp), CN-alpha and Cm-alpha of supersonic and hypersonic rockets and re-entry vehicles. In addition, on a separate screen HyperCFD displays and plots CN-Body, CN-Fins, CN-Total and Cm-Total as a function of angle of attack (AOA) using up/down controls. HyperCFD uses empirical aerodynamic corrections to the modified Newtonian surface inclination method that allows excellent results from Mach 1.05 to Mach 20. Includes a wide variety of nose cone shapes and fin cross-sections. Nose cone shapes include, conical, elliptical, parabolic, power series Sears-Haack, tangent ogive and spherical segment. Fin cross-sections include single wedge, symmetrical double wedge, arbitrary double wedge, biconvex section, streamline section, round-nose section, and elliptical section fin shapes. HyperCFD is useful to determine supersonic and hypersonic rocket drag and center of pressure location for medium and large scale professional sounding rockets. Finally, HyperCFD 10.xx models hypersonic glide vehicle (HGV) aerodynamics. More ...

FinSim 10, Flutter Velocity Tool: Quickly and easily predict fin flutter velocity, UF and fin divergence velocity, UD for any rocket while specifying fins in the Fin Geometry screen by simply using a slider bar. Predict flutter velocity from sea level all the way to maximum altitude that was defined on the main AeroFinSim analysis screen. Get instant flutter velocity feedback while specifying fin geometry and get an idea of fin shock angle and fin Surface Mach number that a fin will experience during supersonic flight. Flutter velocity accuracy is enhanced by using the NASA web site atmospheric model that predicts free stream pressure (P) temperature (T), density (r)and speed of sound as a function of altitude from sea level while flying through the Troposphere (h < 36,152 feet), Lower Stratosphere (36,152 feet < h < 82,345 feet) and finally the Upper Stratosphere (h > 82,345 feet). The atmospheric model used in FinSim is not limited to only the Troposphere or 36,152 feet. More ...

Biden’s "Gift" to America!
A Shattered USA Economy
Worst first half for stocks since 1872
Worst year for government bonds since 1865
*No Plan To Fix These Problems*
Democrat-Marxist USA voters are directly responsible for these problems

Impeach Biden for allowing the invasion of millions of military aged men across our southern border including the smuggling of fentanyl that kills over 110,000 Americans every year, unilaterally destroying America's energy independence, emboldening the Russians and Chinese by showing weakness in Afghanistan, being personally compromised by corrupt family foreign-influence deals with the Chinese Communist Party and selling strategic oil to China.
