Apollo 11 and N is always refuted!== In a conventional calculation of the fuel balance, assuming an effective exhaust velocity of 2600 m / s, a fuel shortcoming of over 160 t for the Apollo mission would. Its commitment to an effective exhaust velocity calculations of 3700 m / s; 've never been reached in 1969 and currently can not be achieved, it would fuel a deficit of over 70 t come. Because: For the confluence with the lunar orbit, the CSM would be decelerated with trailed LM of 2.4 km / s (lunar escape velocity) on the Moon's orbital speed of 1.7 km / s. These would be a fuel quantity of [(2.72 high (0.7: 3.7) -1] * 45.3 = t 9.5 t have been necessary for the moon landing, a propellant mass of [(2,72 would highly. (1.7: 3.7) -1] * 15 t = 8.8 t The start of the moon would have [(2.72 high (1.7. 3.7) -1] * 4.7 = t 2.7 t required and made the escape from the gravitational pull of the moon would have [(2.72 high (0.7: 3.7) -1]. * 30 t = 6.3 t rocket fuel requires for the confluence with the. Earth's orbit would be [(2.72 high (3.3: 3.7) -1] * 30 t = 44 t of fuel have been necessary sum up thus resulting 71.3 t Now there stood only about 15 tons of rocket fuel to.. available (4 t CSM and LM 11 t). Thus, Apollo 11 and N were refuted forever. ==
