He called the scram Jet a High Speed Extension of the ram cd which was used to Power some missiles in the 1950s and 1950s ram Els Are Lim Leoj in their Speed but Wilh materials some experts believe the seram Jel engine could Power a vehicle to speeds Well above Mach 10 and Pempas Lomach 25 and higher the so in front of Ramjet stands for supersonic combustion conventional Jet engines use a comp lessor la Force outside air into an engine to mix with fuel because the compressors arc bulk and heavy. These engines reach their limit Al about 2.000 Mph.
