Saturn V F-1 Engine
Chat with us now. It is a single start engine producing 1, pounds of fixed thrust, via the biopropellant mixture of RP-1 kerosene and liquid oxygen, which equates to approximately 32 million bhp. Although now over 50 years old, current research and development into an F-1B upgrade may see the engine yet again take mankind aloft in years to come. Historically used solely on the Saturn V launch vehicle, the F-1 could also serve as a general purpose engine for 3D modelers interested in designing more futuristic or fantasy spacecraft.
Earlier research and development and test versions depicted in many photos have different types of high pressure fuel lines straight rather than U shaped as well as other minor variations. Modeled with precision using detailed scale blueprints, schematic diagrams and extensive photographic research.
The download ZIP file contains 3 versions of the F1 engine: 1 - Flight version although rarely depicted in photographs the 5 installed F1 engines were covered with asbestos blankets and foil batt insulation to protect against the massive temperatures of launch.

Report Content. Read more about enhanced license tiersor contact us at enterprise turbosquid.The F-1 is a gas generator-cycle rocket engine developed in the United States by Rocketdyne in the late s and used in the Saturn V rocket in the s and early s.
The F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed. Rocketdyne developed the F-1 and the E-1 to meet a U. Air Force requirement for a very large rocket engine. The E-1, although successfully tested in static firing, was quickly seen as a technological dead-end, and was abandoned for the larger, more powerful F The Air Force eventually halted development of the F-1 because of a lack of requirement for such a large engine.
F-1 Rocket Engine
However, the recently created National Aeronautics and Space Administration NASA appreciated the usefulness of an engine with so much power and contracted Rocketdyne to complete its development. Test firings of F-1 components had been performed as early as The first static firing of a full-stage developmental F-1 was performed in March In Decemberthe F-1 completed flight rating tests. Testing continued at least through Early development tests revealed serious combustion instability problems which sometimes caused catastrophic failure.
Eventually, engineers developed a diagnostic technique of detonating small explosive charges which they called "bombs" outside the combustion chamber, through a tangential tube RDX, C4 or black powder were used while the engine was firing.
This allowed them to determine exactly how the running chamber responded to variations in pressure, and to determine how to nullify these oscillations. The designers could then quickly experiment with different co-axial fuel-injector designs to obtain the one most resistant to instability.
These problems were addressed from through Eventually, engine combustion was so stable, it would self-damp artificially induced instability within one-tenth of a second.
The F-1 engine is the most powerful single-nozzle liquid-fueled rocket engine ever flown. The M-1 rocket engine was designed to have more thrust, but it was only tested at the component level. Also, the RD produces more thrust, but has four nozzles. A turbopump was used to inject fuel and oxygen into the combustion chamber.The only thing left to do is have an acrylic cover made for it. It was about six months of work in my little amount of spare time.
Not with Carlos, but with the model.
I had bought the model from Accurate Models directly the first time and had commissioned another model builder that I found here on cS to build it. After a year and a half of having my model he went bust and my model went with it so I then had to find another model.
I finally managed to buy one from eBay as by that time the model was out of production. I was working with the folks from Accurate Models to try and put me a kit together from some of the prototype parts and left over production parts those are some great folks at Accurate Models!
I was glad to find that one on eBay and have not seen one since. I found Carlos through a modeling site that listed a number of folks that would build models for hire. At that time Carlos' site said he was here in Savannah GA. It turned out he had moved to Florida but we hooked up and I sent him the model for building. It turns out that the model was a good challenge and that the kit was short some parts that he had to scratch build.
He kept me informed ever step of the way with notes and pictures. He is a super guy to work with and if you can convince him to build another one you should be well pleased. I have now to plan when I can go and pick up this gem as there is no way it's going through the mail! Thank you sir, you are too kind. Yes it was challenging, but a very rewarding portfolio piece. I can't describe the sense of accomplishment and satisfaction I got when I was taking the photos.
Pure elation. I'm sorry you had to go through so much nonsense to finally get one. If anyone is still interested in the F1 kit, we are going to make a summertime batch of 10 kits. You can now purchase it at our website through PayPal, much easier than before. International orders e-mail us for a shipping quote.
The last image compares the model with an actual F-1 Lox inlet cover center cover for scale. Thanks Pascal - truly a superb job. A couple of questions: Is this model made of plastic or resin?
And how hard is it to build? I've never built one but to quote from the manufacture's web page "these kits can be built by the average to above-average modeller" although I believe you would have to be a way-above-average modeller to achieve a finish like the examples above. I have done total 10 plating versions, six silver, three bronze and my last, a 24 karat gold version.
This one is related to the 60 years of the F It is one of my most prized possessions. Posts: From: Santa Paula, Ca. How much was the plating? Will you plate the Topping LEM?
If not I'd like to try one if you could give me an idea of cost. Models or fine art? Pascal certainly stepped it up a notch with his latest iteration. Pretty cool! Does anyone have any leads or info on how I can get hold of plans or better still a kit of this diorama?The thrust chamber is the most recognizable portion of the F-1 rocket engine.
While the entire thrust chamber assembly consists of a gimbal bearing, an oxidizer domean injectora thrust chamber body, a thrust chamber nozzle extensionand thermal insulation, this page will deal with the thrust chamber itself.
This page will additionally refer to the thrust chamber body, without its nozzle extension, unless otherwise specified. Propellants were delivered to the thrust chamber from the turbopump via the high-pressure ducts. The thrust chamber provided a combustion chamber for burning propellants and an expansion nozzle for expelling gasses produced by the burned propellants at high velocity to produce thrust.
The thrust chamber was tubular-walled and regeneratively fuel-cooled to the expansion ratio plane. The nozzle was bell-shaped and, with its uncooled nozzle extension, had an overall expansion ratio of There were four sets of outrigger struts attached to the exterior of the thrust chamber: two sets of the struts were turbopump mounts and the other two were attach points for the gimbal actuators.
The thrust chamber incorporated a turbine exhaust manifold at the nozzle exit and a fuel inlet manifold at the injector end which directed fuel to the fuel down tubes.
Brackets and studs welded to the reinforcing "hatbands" surrounding the thrust chamber provided attach points for thermal insulation blankets. Click image for a x pixel version of this image in a new window. Adapted from p. Its body was constructed of tubes; fuel flowed through these tubes, providing regenerative cooling to prevent the tube material from melting during engine operation. The fuel entered the fuel inlet manifold at the forward end of the thrust chamber, where it was directed to the regenerative cooling tubes.
Every other tube comprising the thrust chamber was a "down tube". Cleanup and adaptation by heroicrelics. At the exit plane of the thrust chamber was a fuel return manifold; fuel was directed back up the adjacent fuel return tubes to the fuel injector manifold at the forward end of the thrust chamber. From "F-1 Engine Development" by D. Aldrich and D.
Sanchini on page 46 of the the March issue of Astronautics. Located in the Saturn V Collection, Dept. Scan and cleanup by heroicrelics. The tubes comprising the thrust chamber were heavily jacketed at the combustion chamber and were reinforced by a series of bands around the nozzle. The thrust chamber's tubes were constructed of Inconel X, a high-temperature, heat-treatable, nickel base alloy.
At this point, the tubes bifurcatedor split in two. Two one-inch-outside-diameter secondary tubes were spliced to each primary tube and formed the chamber from the to the expansion ratio plane.I come across many Saturn V diagrams which, while interesting, are not so interesting that they necessarily merit their own separate page.
I have created this page as a repository for such diagrams. Here is a very early Saturn V diagram; note the of the spacecraft-lunar module adapter SLAwhich has a shape more commonly associated with a Saturn I shorter conical section with a cylindrical section on top :.

Marshall Space Flight Center station numbers are in inches and are defined such that station is the gimbal plane of the engines.Battleship game codility
This scheme seems to have started with the Jupiter missile the first ABMA missile with an engine with gimbal capability; the Jupiter's S-3D engine was inches tall from the exit plane to the gimbal plane and continued on up to the Saturn V. This leads to the somewhat unusual need, in the case of the much-larger F-1 engine, for negative station numbers. In this diagram, the Saturn V is 4, inches feet 10 inchestall; the non-standard SLA no doubt contributes to the short stature of the rocket in this diagram.
Somewhat oddly, this diagram representing an early Saturn V configuration appeared in an SA Apollo 4 document, published in Februarywhich is far too late to depict such a SLA. Louis Salmon Library, University of Alabama in Huntsville, which also makes this document available as a 5. Scan and adaptation by heroicrelics. A similar diagram, with the stages and major stage components called out.
The height of the launch vehicle is quoted at Located in the Saturn V Collection, Dept. Scan and cleanup by heroicrelics. I have two versions of this diagram, which shows each stage, their major components, and their respective manufacturers, one diagram with an inset showing the complete vehicle and one without the inset.
No one seems to know the exact height of the Saturn V, as I've seen, and In reality, its height probably varied, as I imagine that weight of the propellants and the extreme cold of of its cryogenic propellants may have caused it to contract slightly. The difference between and Adapted rom page 6A of the Apollo 4 Press Kit. Located in the Kramer Collection, Dept. Scan, clean-up, and adaptaion by heroicrelics. This diagram is from the Apollo 4 Press Kit Apollo 4.
Driving home my point about no one knowing the exact height of a Saturn V, we have this diagram, of SA Apollo 14which shows a height of feet. To add insult to injury, the gross weight is 6, pounds, well over the 6, pounds shown above. Of course, as the program progressed, the Apollo spacecraft grew in weight, and the engines of the various stages were uprated slightly to compensate. This diagram merely notes the vehicle's height as feet, the pre-launch launch vehicle gross weight as 6, pounds, and the following vehicle components.
Located in the Mauldin Collection, Dept. Scan and reconstruction by heroicrelics. Visually, SA through SA are identical to each other but distinguished from earlier launch vehicles by the fact the four ullage motors were removed from S-II interstage. On SA, the S-IC stage also deleted four of the eight retromotors which, installed beneath the engine fairings, are not visible in this diagram.
Analysis and previous flight experience had shown that adequate separation distance between the S-IC and S-II stages and adequate propellant seating in the S-II stage could be achieved with the deletion of these motors although the coast period between S-IC engine cut-off and the S-II engine start command was extended by one second, to ensure adequate separate between the two stages.
As it turned out, separation distance on SA was less than predicted and additional analysis showed that failure of one retromotor would fail to provide the desired separation distance or, in the extreme case, even allow recontact of the stages.Rockets are basically just propellant with some skin around it to keep it in place and they have a thing on the back that can throw said propellant really really fast.
And to way over simplify it even more, the faster you can throw that propellant, the better. The easiest way to do this is by storing all the propellant in your tanks under really high pressure, then put a valve on one end of the tank and a propelling nozzle that accelerates the propellant into workable thrust.
No crazy pumps, or complicated systems, just open a valve and let er rip. But pressure fed engines have one big limiting factor.How to remove a stuck relay
Pressure always flows from high to low, so the engine can never be higher pressure than the propellant tanks. In order to store propellant under high pressure, your tanks will need to be strong and therefore thicker and heavier. Look at composite overwrapped pressure vessels or COPVs. Increase the enthalpy. Enthalpy is basically the relationship between volume, pressure and temperature.
A higher pressure and temperature inside the combustion chamber equals higher efficiency and more mass shoved through the rocket engine equals more thrust. So in order to shove more propellant into the engine, you could either increase the pressure in the tanks, or just shoot the propellant into the combustion chamber with a high powered PUMP. Huh, the second option sounds like a good idea! So what if you took a tiny rocket engine and aimed it right at a turbine to spin it up really fast?
Welcome to turbopumps and the staged combustion cycle! This is probably one of the most common types of liquid fueled rocket engines used on orbital rockets.The Saturn V Story (Space Race Documentary) - Spark
The gas-generator cycle works by pumping the fuel and oxidizer into the combustion chamber using a turbopump. The turbopump has a few main parts, a mini rocket engine called the preburner, a turbine connected to a shaft and then a pump or two that push propellant into the combustion chamber. You might hear the turbopump assembly called the powerpack because it really is what powers the engine.
In the open cycle system, the spent propellant from the preburner is simply dumped overboard and does not contribute any significant thrust. This makes it less efficient since the fuel and oxidizer used to spin the pumps is basically wasted. This makes starting a gas generator tricky. So back to the turbopumps, remember, pressure always flows from high to low, so the turbopumps need to be a higher pressure than the chamber pressure.
This means the inlets leading into the preburner is actually the highest pressure point in the entire rocket engine, everything downstream is lower pressure.
But notice something here. Notice how black the smoke is coming out of the preburner exhaust…. Why would it be so sooty compared to the main combustion chamber which leaves almost no visible exhaust? Like thousands and thousands of degrees Celsius. Running at the perfect fuel and oxygen ratio is the most efficient and releases the most energy, but it also produces a crazy amount of heat.
In order to keep the temperatures low, you can run the preburner at a less than optimal ratio, so either too much fuel known as fuel rich or too much oxidizer or oxygen rich. The highly pressurized unburnt carbon molecules bond and form polymers which is a process known as coking.
This soot starts to stick to everything it touches and can block injectors or even do damage to the turbine itself! What if you could just pipe that hot exhaust gas and put it into the combustion chamber? Welcome to the closed cycle! The closed cycle or staged combustion cycle increases engine efficiency by using what would normally be lost exhaust and connects it to the combustion chamber to help increase pressure and therefore increase efficiency.
