This led to several production engines including the mono-propellant De Havilland Sprite and the Screamer, dating back to 1956. Between 1953 and 1957 the British company,

It is essentially the thrust per pound of propellant consumed per second. Isp = F / ṁ, where Isp is the specific impulse in seconds. Although a rocket designer might be tempted to always use the highest Isp propellant combination available, the propellant density is also a factor. black and gold marble wall tiles
