Can coking be avoided by pumping fuel after shutdown?

As I understand it, coking in kerolox engines occurs when the engine shuts down and fuel flow stops, causing fuel still in the coolant channels to overheat and decompose. Can this avoided ...

Has combustion chamber water injection been used in RP1 rocket engine design?

Goddard’s rocket, the V2 rocket and Redstone all used water in their Alcohol fuel for combustion temperature control. To the best of my knowledge, water has not been used in RP1 fueled rockets for ...

Propellant Density Calculation for LOX/Kero

I am trying to make sense of the equation for propellant density calculation, rho=(rw-1)/(rw/bo+1/bf). Sutton, 7th edition, gives this equation (7-2) as: $ \ \ \ \rho_{av} = \frac {\rho_o\rho_f(1+r)} {...

Falcon-9's subcooled LOX is continuously refrigerated in-situ, what about its subcooled RP-1?

@Uwe's answer to Why would sub-cooled LOX tanks need to “topped-off” until the last minute or so? explains how subcooled LOX is kept cold and dense by "in situ refrigeration"; helium is bubbled ...

What's the viscosity of chilled RP-1?

I would like to compare the viscosity of "chilled" RP-1 as it is used for Falcon 9 launches to that of some everyday fluids. However, I am unable to find this information elsewhere. Would you please ...

Kerosene engine film cooling

So it is clear that kerosene fueled engines use two fluids for film cooling via injection in the combustion chamber, throat, or nozzle. (That is "true film cooling" and not just a fuel rich outer ring ...

Why did the Americans abandon kerosene after F-1 while the Soviets continued to develop it to very high sophistication?

What is the reason behind America's switch to LH2/LOX, and (USSR's) Russia's decision to stay with it and develop it to spectacular technical sophistication such as the Oxygen-rich staged combustion ...

How would the Saturn V have differed if the first stage was using liquid methane and LOX?

We have seen here the excellent answer to the question: How would the Saturn V have differed if the first stage was also LH2/LOX? What if liquid methane would be used instead of kerosene? Would the ...

Why is TEA-TEB chemical ignition used instead of spark ignition?

Both the Saturn V and the Falcon 9 use TEA-TEB to ignite their kerosene-fueled engines. TEA-TEB is pyrophoric, igniting spontaneously on contact with air. This poses handling issues; it must be stored ...
