T-Minus Engineering B.V. is a company that is specialized in developing rocket systems for scientific purposes. The company was founded as a spin-off of Delft Aerospace Rocket Engineering, and the four co-founders acquired many years of combined experience in the development of rocket systems. Next to that, the fact that the founders studied Aerospace Engineering and Electrical Engineering at the Delft University of Technology means that a thorough theoretical background is present as well. Finally, two of the entrepreneurs have professional experience in the sounding rocket business, having worked for the Swedish Space Corporation at Esrange Space Center as payload manager, project manager, test engineer and ground safety engineer. The core competencies of T-Minus Engineering are: • Rocket propulsion • Flight computers and on-board electronics • Structural design • Aerodynamic design • Operations and safety With these competencies, we hope to provide a valuable contribution to your project.
