Hi there and Merry Christmas!
I came accross your website while I was searching for related things.
I am a Physics graduate student and have done projects related with the areas described bellow.
I am also part of a small group of people (students and professionals) with the same interest as you both as a hobby and as a profession (rocket models, UAVs, missiles) and would like to offer some of our services to you.
Just to mention a few areas of expertise that we can cover: we have experience in missiles (some of us worked with guided "systems" for the industry), avionics, trajectory dynamics/ballistics (interior and exterior ballistics).
We would also like to cooperate in developing other avionics related items useful for rocketry hobby. We can offer digital altimeters, timers, parachute deploying systems, integrated systems etc.
Please be aware that we do this as a free time project so limitations may occur. Also we can't provide details about industry's restricted technologies.
We are here as hobbyists!
Enough with introduction. Bellow I am including an example of a project that we designed and flew. We are opened for requests for other devices that you need (some of them we may already have). We are flexible and we can discuss the details of the projects of interest to you and we can actively participate in the developing of the end product that you want/that will fit you specific task. The price for each project will be proportional with the complexity of the project.
Example of ALT-05:
- records altitude every 0.3 seconds
- records acceleration, temperature and angular displacement (velocity)
- you can download the data through a serial connection on a computer for post-flight analysis
- starts taking data after launch acceleration is detected
- can deploy parachutes at two preset altitudes
Software associated with ALT-05: can compute the trajectory of the rocket doing from the inertial measurements (acceleration, angular displacement). It employs Runge-Kutta differential solver with variable time-step (similar with the ones employed in the industry/military). It can compute the speed of the rocket and the characteristic frequency of oscillation along the trajectory. Based on simple inputs and flight data it provides the aerodynamic coefficients of the rocket as determined from the flight... and many other things already there or that can be added quickly
I hope this post contains useful information for you and we wait offers of collaboration.
