Sir: After reading the article 'Mystery WW2 German Liquid Rocket Engine' by Martin Postranecky (Space Chronicle, Vol. 66, Suppl. 2, pp.46-48) I thought the following. If you compare the injection method of the mystery WW2 German liquid rocket engine with the Viking rocket engines of Ariane 1, 2, 3 and 4 SLV's (central fuel injector and sidewards rows of oxidiser injectors), you can conclude that both are using the same method.
