Various design issues were identified and solved during V-2 development and testing:
> To reduce tank pressure and weight, high flow turbopumps were used to boost pressure.:35
> A short and lighter combustion chamber without burn-through was developed by using centrifugal injection nozzles, a mixing compartment, and a converging nozzle to the throat for homogeneous combustion.:51
> Film cooling was used to prevent burn through at the nozzle throat.:52
> Relay contacts were made more durable to withstand vibration and prevent thrust cutoff just after lift-off.:52
> Ensuring that the fuel pipes had tension-free curves reduced the likelihood of explosions at 4,000–6,000 ft (1,219–1,829 m).:215,217
> Fins were shaped with clearance to prevent damage as the exhaust jet expanded with altitude.:56,118
> To control trajectory at liftoff and supersonic speeds, heat-resistant graphite vanes were used as rudders in the exhaust jet.:35,58
Can anyone comment on if a lot of these issues had known soluctions before V-2, or was it really that successful at coming up with revolutionary solutions to the problems?
What role did Von Braun play, mostly an overall system architect, or as one who came up with innovation to solve the individual challenges, or both?
Can anyone recommend a good book covering the various contributions of the V-2 team as well as the work of Goddard over the formative years, let's say late 20s to mid 40s?
