Did the Saturn V F-1 rocket engines correspond to NASA’s published data? – and were there fundamental design flaws in the F-1 engine?
This article focuses on the the F-1 engine used in first stage of the Saturn V. According to the investigation conducted by the Gennady Ivchenkov, PhD, this engine had fundamental design flaws.
This research indicates that these engines could only lift off the pad a modified version of the Saturn V – just 2000 tons instead of the stated 2,800 tons.
For example, the F-1 tubular combustion chamber and nozzle were unable to provide the specified pressure and engine thrust. Furthermore, calculation of heat transfer and the stress applied to tube wall material reveals that:
Consequently, the pressure in the F-1 combustion chamber is likely to have been significantly lower than stated, due to fundamental shortcomings in the tubular cooling system of F-1 engines.
The launch weight of the Apollo Saturn V is found to be considerably lower than stated by NASA and, accordingly, could not ensure the accomplishment of the Apollo Moon program.

About the Author
Gennady Ivchenkov graduated from the faculty Power Engineering of the Bauman Moscow State Technical University (Bauman MSTU) in 1974, majoring in Aircraft engines (Rocket Engines Department) (3rd specialization – solid propellant rocket motors; 1st specialization – LRE (liquid rocket engines)).
In 1980 he defended his thesis for the degree of Candidate of Technical Sciences (Ph.D.). The topic of the thesis is a study of combustion in high-speed gas flow. He worked as a researcher at NIIGRAFIT company (research of ablation of carbon-carbon materials), and then as a senior researcher in the department of NIIRP (on the subject of missile defense), then on topics related to the development of HF chemical lasers based on fluorine-hydrogen rocket engines. At the same time he received a second degree at the Faculty of Engineering of the Moscow State Institute of Radio Engineering, Electronics and Automation (MIREA) in specialty Optical Systems. He was teaching as an Associate Professor in the Khimki branch of Moscow Aviation Institute. Since 1994 he has worked in Canada on the development of fiber-optic devices.
Gennady Ivchenkov holds seven US patents (fiber-optic sensors and switches).
