NOTE-1: All AeroRocket programs are compatible with Windows XP, Windows 7 and Windows 10 (64 bit) desktop computers having screen resolutions of at least 1024 X 768 pixels with 256 colors. AeroRocket programs are developed using Visual Basic 6 and are therefore not compatible with devices like the 4G LTE smartphone.

NOTE-2: Software Installation: Download the .zip file and copy to the desktop. Then, double-click the .zip file to run WinZip which extracts and installs the computer program. If this procedure does not work then copy the .zip file to the desktop then right-click the .zip file and click Open with WinZip or Extract to... to run the installation program. Follow the setup instructions and use provided defaults for proper installation. For Windows 10, double click the .zip file then click extract to copy the contents to a separate folder and finally double click setup.exe to install.

NOTE-3: Input data for all AeroRocket programs must use a period (.) and not a comma (,) and the computer must be set to the English (United States) language. For example, gas constant should be written as  Rgas = 355.4 (J / kg*K = m^2 / sec^2*K) and not Rgas = 355,4. The English (United States) language is set in the Control Panel by clicking Date, Time, Language and Regional Options then Regional and Language Options and finally by selecting English (United States). If periods are not used in all inputs and outputs the results will not be correct.

NOTE-4: To install AeroRocket software the user requires WinZip, the original and most popular compression utility for Windows. Please click for more information.

AeroCFD 7.0 (2.7MB) $25.00 TOP
Finite Volume CFD Analysis Program with Fins
Detailed Information 

AeroCFD is an axisymmetric three-dimensional and two-dimensional Computational Fluid Dynamics program that solves the compressible Euler equations for subsonic, transonic and supersonic flow using automatic mesh generation and graphical results visualization. AeroCFD provides a maximum of 100 cells in the axial direction, 50 cells in the transverse direction and 10 cells in the circumferential (3-D) or thickness (2-D) direction. The latest version of AeroCFD has increased the number of discrete finite-volumes available for analysis from 18,000 cells to 50,000 cells. Due to its "true" 3-dimensional formulation, AeroCFD provides non-zero lift and non-zero pitching moment for axisymmetric shapes with fins at angle of attack without requiring computational times exceeding one hour. Model geometry is specified by selecting from a library of standard shapes. Nose sections are defined using one of five basic shapes that include Conical, Ogive, Elliptical, Parabolic and Sears-Haack with power series coefficient. The user has the option for adding up to two constant diameter sections, one variable diameter transition section and one variable diameter boat tail section to complete the library of user-defined shapes. For added flexibility AeroCFD can import up to 1,000 X-R data points for generating axisymmetric and two-dimensional designs that require grid clustering in regions where shock waves dominate the flow. Flow fields are displayed using fill-contour plots, line-contour plots and surface distribution plots for pressure coefficient, pressure ratio, temperature ratio, density ratio and Mach number. The RESULTS section clearly displays FX, FY, MZ, CX, CY, CM, CD, CL, base drag, surface friction drag and center of pressure location. The latest version displays fin axial force and fin normal force in selected UNITS. All output can be sent directly to a color printer.


VisualCFD 3.0 (3.4MB) $25.00 TOP
Space-Marching CFD Training Code
Detailed Information

VisualCFD is a CFD training code designed for the analysis of two-dimensional and axisymmetric supersonic flow using the MacCormack space-marching method and the analysis of three-dimensional subsonic flow using panel methods. This new CFD program solves supersonic flow in seconds by marching the solution downstream using the MacCormack forward-predictor, backward-corrector method. A complete derivation of the equations, discussion of the theory and program listing will be provided in the report, EulerCode.pdf. The 16-page Euler Code Theory report will be provided FREE with every purchase of VisualCFD and will be distributed as part of the VisualCFD.zip download file.


Nozzle 3.7 (4.9MB) $25.00 TOP
Converging-Diverging Nozzle Analysis
Detailed Information

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.


AeroSpike 2.6 (4.8MB) $25.00 TOP
Minimum Length Nozzle Design & AeroSpike Nozzle Design Program
Detailed Information

AeroSpike performs 2-D and 3-D Minimum Length Nozzle (MLN) design using the method of characteristics. In addition, for annular and linear aerospike nozzle designs AeroSpike performs an expansion-wave analysis from the throat of the thruster, where Mn=1, to each point on the plug contour to determine CF, CFvac, ISP and ISPvac and determines the shape of the optimized aerospike nozzle. In addition, AeroSpike plots CF, Thrust, CFvac, ISP, and ISPvac verses pressure ratio (Pc/Pa) on a semi-log scale as well as generating color contour plots of Mn, P/Pc, T/Tc and R/Rc. New in this version is the ability to include base thrust pressure to determine truncated base contribution to total thrust and thrust coefficient (CF).


HyperCFD 3.5 (2.5MB) $25.00 TOP
Supersonic CFD Analysis Program
Detailed Information

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 rocket drag and Cp location for level 3 flights. New in this description is a methodology to determine thermal loads into the airframes of supersonic and hypersonic rockets using temperature distribution (T/Tinf) results from HyperCFD and AeroCFD. In addition, a Microsoft Excel thermal analysis (50 KB) spreedsheet is available as a free download. Also new in this description is a slender missile analysis that validates HyperCFD for the prediction of drag coefficient (Cd) and center of pressure location (XCp) for the flight regime which extends from Mach 1.05 to Mach 6.
