China Jet Fuel? What Is RP1 or RP 2, ANY IDEAS

[4x4]

Anyone out there can give explanation to quality/ additive contents of Jet fuel in China, and the relative differences between RP1 and RP2

[doubleu-anker]

RP1 and RP2

The only thing I can think of is that the RP would mean Rough-cut Propellant. One rougher than the other!!:}

There are five types of jet fuel are covered by current Chinese specifications. Previously, each grade was numbered with a prefix RP, they are now renamed No 1 Jet Fuel, No 2 Jet Fuel etc. RP-I and RP-2 are kerosines which are similar to Soviet TS-1. They both have low flash point (min 28 degrees C).

RP-1 freeze point is M60 degrees C and RP-2 is M50 degrees C.

RP-3 is basically as Jet A-1, produced as an export grade.

RP-4 is a wide-cut type fuel similar to Jet B and Soviet T-2.

RP-5 is a high flash point kerosine similar to that used in the by naval aircrafl operating on aircraft carriers.

Virtually all jet fuel produced in China is now RP-3 (renamed No 3 Jet Fuel).
