Finite Volume CFD Analysis Program with Fins
Detailed
Information Buy AeroCFD
AeroCFD
is an axisymmetric threedimensional and twodimensional
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
(3D) or thickness (2D) direction. The latest version of AeroCFD has
increased the number of discrete finitevolumes available for analysis from
18,000 cells to 50,000 cells. Due to its "true" 3dimensional formulation,
AeroCFD provides nonzero lift
and nonzero 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
SearsHaack 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 userdefined shapes. For
added flexibility AeroCFD can import up to 1,000 XR data points
for generating axisymmetric and twodimensional designs that
require grid clustering in regions where shock waves dominate the flow. Flow fields are displayed using fillcontour plots, linecontour
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.

Airplane Flight Dynamics & Stability Analysis
for Gliding and Powered Flight
Detailed
Information
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 wingbody 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 sliderbar control to define airplane geometry instead of
timeconsuming CAD geometry definitions. AeroWindTunnel has been
validated from 0.3 Mach to 3.5 Mach using the AeroRocket wind tunnel and other
online sources. In the latest version the
maximum Mach number has been
increased from Mach 4 to Mach 30 for all coefficient plots
verses Mach number and angle of attack. Finally,
AeroWindTunnel
includes a bonus program
called
2DWING™ for the aerodynamic analysis of
twodimensional and finite aspect ratio airfoil sections.

AeroSpike performs 2D and 3D Minimum Length Nozzle (MLN)
design using the method of characteristics. In addition, for annular and linear aerospike
nozzle designs AeroSpike performs an expansionwave 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 semilog 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

Aerodynamic Drag Prediction and Flight Performance Analysis
Detailed Information
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 nosebody 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 ringfin and tubefin stabilized rockets along
with many other new features. Now,
AeroDRAG & Flight Simulation models the
twodimensional flight path of rockets that fly in the proximity
of the gravitational field of the Earth.
