Christian Wilhelm Paul Heylandt was a German engineer whose expertise was in handling compressed gasses. He filed a multitude of patents on this subject and was instrumental in assisting Max Valier in building his liquid fuelled rocket system in early 1930. Heylandt was also responsible for putting Walter Riedel together with Valier. This pairing produced important breakthroughs in liquid rocket systems which were subsequently incorporated by Riedel into the A5 missile at Kummersdorf.

One of Heylandt's patents was filed in January 1921 and was for a liquid oxygen and "carbonaceous substance" carrying missile. Although it looked like a rocket in the patent filing it was a unique design for an explosive shell using liquid oxygen.
