The riddle of the V2 rocket shape

The V2 rocket is instantly recognisable by its extraordinary shape. But where did this revolutionary body shape come from, and why has it not been seen again in missile design since the 1950s? And yet, paradoxically, the shape in stylised form appears on millions of internet pages - why? We continue exploring the A4 / V2 rocket in detail by looking at the surprising origins of the V2’s core body shape. The first designs of the A3 and A5, both prototypes of the A4, had ballistic features emanating from the early 20th-century science of ballistics that the A4 would inherit. But crucially, some elements would change due to a supersonic flow theory revolution in 1930s America. 00:00 Introduction 03:09 V2 rocket shape 05:45 The chubby rocket 09:33 Defining the ogives 12:20 Getting it wrong 14:39 It’s a bullet! 20:25 Handbook of Ballistics 23:02 Heydenreich ogive rule 28:15 Torpedo of 1744 29:24 Ballistics era 35:05 Dr Hermann and A3 38:09 The Windtunnel 47:55 Kurzweg’s rocket 53:29 Von Kármán 56:49 Haack’s paper of ’41 1:00:34 Inside the outside 1:04:23 Summary 1:05:35 The V2’s ghost in art & culture 1:11:34 Mole bunker?
