| 41. | Some rockets use gas from a gas generator to pressurize the fuel tank; usually, this is exhaust from a turbopump.
|
| 42. | The turbopump issues that plagued early Rocketdyne engines were also resolved in Jupiter much earlier than the Air Force's missiles.
|
| 43. | The mission ended prematurely at 73.6 seconds after launch on August 17, 1958, due to a turbopump failure.
|
| 44. | The titanium fuel turbopump uses a two-stage pump with inducer and is actuated by a two-stage axial turbine.
|
| 45. | The pressure level in the turbopump gearbox was also modified slightly to prevent a recurrence of the malfunctions on 13A and 15A.
|
| 46. | Following launch a fuel leak between the turbopump and gearbox caused the main engine to lose 20 25 % of its thrust.
|
| 47. | In January last year, another Ariane crashed into the Atlantic after the cooling system failed on the third stage's turbopump.
|
| 48. | Similarly generated steam was used to drive the turbopump in the German V2 rocket, and the pumps in several other rocket engines.
|
| 49. | Six consecutive Thor and Atlas launches failed during February April 1958, although not all of them could be attributed to turbopump problems.
|
| 50. | He developed the RD-214 for the R-12, which consisted of four combustion chambers sharing a common turbopump assembly.
