In this one second, the gas generator that supplies the turbopump has consumed 17.5 gallons of RP-1 fuel through a 2 inch diameter pipe, and 5.1 gallons of oxidizer through a 1 inch diameter pipe to combust and drive the two-stage impulse turbine containing 109 blades in the 33-inch diameter first stage and 119 blades in the 35-inch diameter second stage rotor. A Study on the Design of LOx Turbopump Inducers, Lucrezia Veggi et al., International Symposium on Transport Phenomena and Dynamics of Rotating Machinery Maui, Hawaii, December 16-21, 2017. In its next evolution, the RS-25 design will be changed to make it a more affordable engine designed for just one flight and certify it to even higher thrust which it is very capable of to make SLS an even more impressive launch vehicle. Space-Launch Vehicles, 1926 1991 (College Station, Texas: Texas A&M University Press, 2007). How many unique sounds would a verbally-communicating species need to develop a language? https://www.enginehistory.org/Rockets/RPE08.11/RPE08.11.shtml, https://home.kpn.nl/panhu001/Saturn_V/Saturn_V_info/SatV-Apollo_perform_char.html, Sectioned Rocketdyne F-1 Engine MK-10 Turbopump (Tom Fey). This subreddit is not an official outlet for SpaceX information. In this one second, from this single engine, 34 million BTUs of energy have been released, enough to raise the temperature of an Olympic sized swimming pool 6.2 F.

It was quite an experience.". Each of the bell-shaped F-1 engines weighed over nine tons, generated 1.5 million pounds of thrust, and had a potential energy output equal to the power of eighty-five Hoover dams. Acceptance testing took a total of 495 sec, for a mission duration of 165 sec. United States of America PROPULSION-Components (Engine Parts) Rocketdyne Division, Rockwell International Corporation Overall: 5 ft. 2 in. As rocket engines go, the RS-25 may be the most advanced, operating at higher temperatures, pressures, and speeds than most any other engine. A Body Force Model for Cavitating Inducers in Rocket Engine Turbopumps, William Alarik Sorensen et al., MS Thesis, Massachusetts Institute of Technology, September 2014. Chamber pressure of the F1 on SaturnV was 1015psi and the chamber pressure for the upcoming Raptor engine is 4351psi (300 bar).

The highest-time engine ran a total of 800 sec.

Each F-1 engine had more thrust than three Space Shuttle Main Engines combined. Fuel entered the middle manifold and traveled down half the thrust chamber tubes and up the other half to regeneratively cool the thrust chamber. Rather than seeking a direct analytical answer to this question, they chose instead to select the largest thrust anyone could imagine and do the preliminary design for an engine that could achieve that thrust.

The engine produces 60,000 pounds of thrust and the turbopump utilizes two counter-rotating assemblies mounted in a single housing.

The combined propellant flow rate of the five F-1s in the Saturn V was 3,357 US gallons (12,710 l) per second. An F-1 engine is installed vertically as a memorial to the Rocketdyne builders on De Soto across the street from the old Rocketdyne plant in Canoga Park, California. When work on the F-1 began, the most powerful

But, to maintain the same pressure and flow rate, the turbopump needs to run at a high rotational speed. WebBN teamed with Rocketdyne to design and build a second turbopump for NASAs LCBT Program. The first static firing of a full-stage developmental F-1 was performed in March 1959. With 600 horsepower turbines that drive the pump at 36,000 revolutions per minute, the turbopump puts out 600 gallons of -255 degree Fahrenheit liquid methane per minute.

There were small performance variations between engines on a given mission, and variations in average thrust between missions.

Thanks for the link to the higher quality version. Rocket engines are among the most amazing machines ever invented. Thats also why they test rocket engines on the ground under highly instrumented and controlled conditions. LOX pump failures resulted in explosive fires that converted failed components into ions.
