The Correspondence between the Rocket Pioneers Johannes Winkler and Hugo Hückel
By Wolfgang Both [1], Karlheinz Rohwild [2], Reinhard Sagner [3]
Abstract:
In longstanding work all letters between rocket pioneer Johannes Winkler and businessman Hugo Hückel were transcribed and digitally preserved for futher research. Johannes Winkler launched the first European liquid propellant rocket in March 1931, Hugo Hückel was for about two years more than his sponsor. Their correspondence is the only document giving an insight in the development and modifications of the Hückel-Winkler-No.1 rocket (HW1), the problems and solutions for design, mechanical and chemical problems of „Modell No. 2“ rocket and the first ideas of the (not realized) „Modell No. 3“. Several aspects of their technical and commercial correspondence will be enlighted to take a look back to the beginnings of astronautics.
