Russia is also working to switch the Soyuz-2 from RP-1 to "naftil" [10] or "naphthyl". [11] [12] After the RP-1 standard, RP-2 was developed. The primary difference is an even lower sulfur content. However, as most users accept RP-1, there was little incentive to produce and stock a second, even rarer and more expensive formulation.
A highly refined form of jet fuel, RP-1 burned much more cleanly than conventional petroleum fuels and also posed less of a danger to ground personnel from explosive vapours. It became the propellant for most of the early American rockets and ballistic missiles such as the Atlas, Titan I, and Thor.
The Aerojet Rocketdyne AR1 is a 2,200-kilonewton-class (500,000 lbf) thrust RP-1/LOX oxidizer-rich staged combustion cycle rocket engine project. [1]The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. [2]

One of the most efficient mixtures, oxygen and hydrogen, suffers from the extremely low temperatures required for storing liquid hydrogen (around 20 K or −253.2 °C or −423.7 °F) and very low fuel density (70 kg/m 3 or 4.4 lb/cu ft, compared to RP-1 at 820 kg/m 3 or 51 lb/cu ft), necessitating large tanks that must also be lightweight and ...
RP 1, RP-1, RP.1, RP1, or similar terms may refer to: DZRB-AM, a Philippine radio station known as Radyo Pilipinas 1 or RP1 News; RP-1, Rocket Propellant 1;
It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle. The rocket uses a similar engine arrangement to the Falcon 9 ; a two-stage rocket using a cluster of nine identical engines on the first stage, and one vacuum-optimized version with a longer nozzle ...
Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...
