AeroWindTunnel
(1) AeroWindTunnel is a delight, no modeler should be without it. Great program.
Ronald Wylie, Australia

(2) AeroWindTunnel, as with your other programs gives the customer a fun to use method for learning new things. One of the things that I've found fun to use is using the sliders and watching the changes in results occur as I watch. I will probably experiment later with testing neutral point and CG changes in gliders (flight results vs predictions).
Ed Brown, Colorado

(3) With all the very High cost software out there, AeroWindTunnel is outstanding for the hobbyist. Its a great program and has my praise.

Nozzle
(1) Your program, Nozzle 3.6 worked beautifully!
Raymond L. Browell, P.E.

2) It's an excellent tool (Nozzle 3.7) that you developed. Although it's not as sophisticated as some of the CFD tools that we have around here, I found it to very useful in approximating the nozzle contours and quickly evaluate the performance of different rocket engines. Thanks.

AeroSpike
1)
I used (AeroSpike) to design several types of nozzle(s) and found your software is really useful.
Takashi Ito, Japan

2) I recently purchased your aerospike calculator for a project I'm working on... Also, just figured I ought to let you know how much I love the program. Its elegantly built, and works quite nicely. A job well done deserves recognition. I'm very happy.

FinSim
(1) In over 20 years of using various engineering analysis programs, I have never had such immediate and thoughtful attention to problems I was having using the software! The problems were not even with FinSim 2.3, but rather the program exporting the data. Fantastic customer service -- I will recommend AeroRocket and John Cipolla to my friends and co-workers in the Aerospace Industry.

AeroCFD
(1) I have enclosed a check in the amount of $10.00 as payment for the upgrade to AeroCFD (VisualCFD 2.8). I can't wait to try out this new version, especially with the ability to input the body definition as an x,r array of input points. Thank you for creating such a fine and useful program.
Brenda Kulfan, Boeing

(2) I have been running AeroCFD (VisualCFD 3.0) continuously for the last 10 days as a validation exercise to generate aerodynamic coefficients as a function of Mach number. WHAT A MARVELOUS PROGRAM! I should have had AeroCFD ten years ago. In one word fabulous... What I also like about AeroCFD is that it is very stable; there were no crashes ... and everything works OK. By the way, I checked the accuracy of AeroCFD regarding predicted against experimental aerodynamic coefficients and found the error < 5% for the ANSR rocket.
Wibo Crucq, The Netherlands

Check out Wibo Crucq's research paper developed using an older version of AeroCFD for the analysis of boat tail projectiles for flights that extend from Mach 0.4 to Mach 6.


HyperCFD

(1) I have a new toy: itís called HyperCFD and it calculates a number of interesting quantities for bodies of rotation that are moving faster than the speed of sound. I bought it because I was interested in the stability of the ďreentry bodyĒ associated with the DF-2 which Jeffrey used to discuss the design (and weight!) of the DF-2ís nuclear warhead but I imagine I will find other uses for it. As it is, I was very surprised at what I found out.

But first, I needed to check its accuracy against some actual data. After all, it says itís for amateur rocket designers, which didnít instill the faith that perhaps it should have in me. It turns out to be pretty good! ... I wont bore you with such checks, but you can look at it if you like. I should note that this fairly blunt shape is one of the most stressing for Newtonian approximations in computational fluid dynamics and in the study Iíve quoted, the other shapes are even better simulated by HyperCFD.
