StarTravel
(140 KB Download -
Password Required):
This MathCAD analysis in pdf format is an
example from the
StarTravel
program
for the elapsed time and velocity of a constantly
accelerating and decelerating observer aboard a
starship. The star is 11.8 light years away, maximum
velocity is 0.5c and the starship is accelerating at
+0.1G for the first part of the flight and -0.1G for
the second part of the interstellar flight.

FusionPropulsion
(105 KB Download -
Password Required): MathCAD
analysis in pdf format is an example from
Fundamentals of Physics, Part 5 by Halliday and
Resnick to determine the energy released from 1.0 kg
of deuterium by the reaction 2H + 2H --> 3He + n.

SprintAssemblyInstructions
(311 KB Download -
Password Required):
Assembly instructions and parts list in pdf
format for the exact
scale model of the
Sprint ABM
model rocket
formerly
sold by AeroRocket a few years ago.
As part of the assembly
instructions this download includes the Sprint ABM
model rocket center of pressure analysis with
airframe, fins and fin-set location dimensions.
Included in the download is the dynamic stability
analysis used by John Cipolla to determine Sprint
ABM period of ascent oscillation using a torsional
pendulum to experimentally determine longitudinal
mass moment of inertia. A must for anyone serious
about actually flying the Sprint ABM because no
hobby rocket simulation computes values for mass
moment of inertia accurate enough for a dynamic
stability analysis.
The model rocket Sprint ABM is an exact scale
model (no clear plastic fins are required for stability) of the Sprint Anti-Ballistic Missile first flown in the
1960's. This model of the Sprint ABM is 21 inches long and 3.5
inches wide at the base and weighs 210 grams without a rocket motor
installed.
An internal launch lug design will avoid unstable liftoff. In
addition, the recovery system includes rear pop-pod recovery
that eliminates the requirement for a separate nose cone.
Other
features include D/E rocket motor propulsion and
post-assembly provision for added nose weight.
At only $25.00
this kit was a unique value that included
the flight simulation design file used during
project development. This is a challenging model
rocket to build and to fly that applies the methods
commonly used to fabricate high power rockets.

NASPCdCURVEFIT
(124 KB Download -
Password Required):
 A Cd verses
Mach number
curve fit approximation was developed from Cd verses
Mach number results for the X-30
National Aerospace Plane using several
VisualCFD 2-D centerline analyses at Mach
numbers 0.2, 0.4, 0.7, 1.0, 1.125, 1.25, 1.5, 2.0,
3.0 and 5. This MathCAD
document in pdf format generates the Cd verses Mach
number approximation from VisualCFD generated X-30
drag forces verses velocity for atmospheric conditions at
150,000 feet from Mach 0.01 to Mach 7.

WindTunnelPlans
(552 KB Download -
Password Required): The
AeroRocket subsonic wind tunnel
 is a suction
system powered by a two speed 1/3 horsepower fan.
The test section is 7 inches wide x 10 inches high x 16
inches long. The
basic subsonic wind tunnel design is by
Donald D. Baals of NASA and was fabricated and
redesigned by John Cipolla using these plans. This
new version of WindTunnelPlans includes an introduction
that includes an experimental method to measure
pitch center of pressure of a flying wing and an engineering drawing of the AeroRocket Force Measurement System that includes
dimensions.

HFV-3X Design Project
Information:
 AeroRocket's version of the HTV-3X called the
HFV-3X represents AeroRocket's proposal for a
new hypersonic spacecraft capable of flight to 300,000
feet and top speed above Mach 5. A new subsonic wind tunnel model of the
HFV-3X has been fabricated for measurement of CD,
CL, CLa, CMa
and L/D for use with
AeroWindTunnel
a subsonic and supersonic aircraft design program. Supersonic drag and lift properties
of the HFV-3X design will be investigated using AeroRocket's
shock-tube
wind tunnel system. For information about the HFV-3X
project please click

8) Lynx Mk.1
Aerodynamic Analysis NEW!
(184 KB Download -
Password Required):
Details for this
sample AeroWindTunnel analysis were derived from the March
31, 2008 issue of Aviation Week and Space Technology
magazine. This download includes the Lynx Mk.1 main
drawing showing scaled plan-view and side-view
shapes, fuselage-wing-vertical fins
dimension sheet and AeroWindTunnel project/geometry files.
Please note this information is a first cut
approximation based on data derived from online
sources and is intended to illustrate how AeroWindTunnel
simulations are quickly and easily performed.
Project file and Fuselage Geometry file require
AeroWindTunnel for aerodynamic analysis and
design. |
