“This document outlines the design, business strategy and concepts behind Stratodyne Aerospace Inc.’s plan to launch small satellites into low earth orbit at low cost and with high reliability. There is a rising need for launch vehicles for small class satellites that aren’t launched in large constellations funded by big aerospace companies. Universities, non-commercial groups, and even individuals are developing microsatellites, mainly CubeSats, and it is this market that Stratodyne would like to target. The Tengine rocket is an air launch to orbit vehicle powered by ten 3D printed, liquid propellant Armstrong-1 rocket engines on the first stage and one 3D printed Armstrong-1V liquid propellant engine on the second stage. The rocket engines will be manufactured using the 3D printed material provided by Shapeways.com as well as electroplating techniques derived from other rocket engine manufacturers. The Tengine will be able to carry 10kg of payload to an orbit of 300 to 500km. The Tengine rocket will provide launch opportunities to individuals, and organizations such as Universities and Amateur Radio groups.”
