Kerosene, also known as paraffin, lamp oil, and coal oil (an obsolete term), is a combustible hydrocarbon liquid which is derived from petroleum.It is widely used as a fuel in aviation as well as households. But it does not answer something … One more Saturn V was used for skylab, the rest distributed for display purposes. Pertinence. Posts: 1966 From: Atlanta, GA Registered: Feb 2007 : posted 04-07-2008 08:47 AM I'm reading The Development of Propulsion Technology for U.S.
In Japan, kerosene can be readily bought at any filling station or be delivered to homes. Why did the Saturn V use kerosene for the first stage instead of hydrogen like the other 2 stages?
First stages can be full of fuel and a bit inefficient. LH2/LOX has been long been popular in … The Saturn V rocket’s first stage carries 203,400 gallons (770,000 liters) of kerosene fuel and 318,000 gallons (1.2 million liters) of liquid oxygen needed for combustion.

Methane/LOX specific impulse is only slightly better than kerosene/LOX and it's about 25% less dense. Réponse préférée. Not to mention, the canisters to hold liquid hydrogen would have been complicated and would have added further weight.
The engines on the next stage would fire, and the rocket would continue into space. Topic: Why Did the S1C Burn Kerosene? A very tall order . Why use a lower power system for the first stage?
Anonyme . NASA thought at first that the Space Shuttle would be taking everything into space, but after the Challenger disaster the expendable rockets made a comeback. So I think we can say that kerosene was always mainstream except for a brief hiatus in the Shuttle era. The Saturn V rockets used for the Apollo missions had three stages. With my limited knowledge, I would expect that the fuel which gives the maximum specific thrust would be used … Each stage would burn its engines until it was out of fuel and would then separate from the rocket. First stages can be full of fuel and a bit inefficient.
In Japan, kerosene can be readily bought at any filling station or be delivered to homes. At this point, shock collars, or condensation clouds, would form around the bottom of the command …
4 réponses. NASA's incredible Saturn V rocket propelled dozens of humans toward Earth's moon. $\begingroup$ Yep, this just illustrates why Saturn V didn't have a hydrogen first stage, and why it's very common practice to have solid rocket boosters on launchers, paired with kerosene or hydrogen -- they're cheap, compact, and high-thrust.
The rocket's first flight, for the Apollo 4 mission, took place 50 years ago, on Nov. 9, 1967. I read that the first stage used kerosene (RP-1) and LOX combination, but liquid hydrogen and LOX for the second and third stages. Why will kerosene be used as the hydraulic fluid (instead of 5606 oil) in the gimbal actuation system of Saturn V’s booster? That’s far from a rule. Space-Launch Vehicles, 1926-1991 by J.D. The Saturn V broke the sound barrier at just over 1 minute at an altitude of between 3 and 4 nautical miles (5.6 and 7.4 km). Since NASA was on such a tight budget, what money they had left went to the shuttle program, which at the time they expected to be very cheap and safe, though that ended up not happening. RP-1 is considerably easier to handle than LH2. The Saturn V notably used RP1 for the first stage, which is just fancy kerosene. The Saturn V reached 400 feet per second (120 m/s) at over 1 mile (1,600 m) in altitude. The first stage had the most powerful engines, since it had the challenging task of lifting the fully fueled rocket off the ground. Not to mention, the canisters to hold liquid hydrogen would have … The Saturn V was very heavy at launch ,just under 3000 tonnes of which over 90% was fuel and oxidizer . The Saturn V FUELDRAULIC Gimbal System. Here are the reasons for the decision. First stages can be full of fuel and a bit inefficient. If you watch the video of a moon rocket lifting off you’ll see those same orange flames and black sooty smoke coming out of the Saturn V, just before liftoff, that you see from the Antares rocket explosion. Il y a 1 décennie. Kerosene is widely used in Japan as a home heating fuel for portable and installed kerosene heaters. $\endgroup$ – Russell Borogove Aug 4 '16 at 13:25 Hunley. On July 16, 1969, kerosene rocket fuel powered the first stage of the Saturn V of the Apollo 11 mission. Kerosene is widely used in Japan as a home heating fuel for portable and installed kerosene heaters.
