These two simple turbocharger derived turbojets were the first two successful turbine engines that I designee and built. At the time, the idea to making a turbojet from a turbocharger core was new and unique, and both engines ran relatively well. Both engines were small and produced only about 10-15 lbs of thrust.
Both engines used centrifugal compressors, single external can combustion chambers, annular inflow turbines, and compressed air impingement starting. The first engine used low pressure fuel vaporizer tubes (40 psi diesel) and a total loss lubrication system. The second engine incorporated high pressure fuel injection (kerosene) and a semi-recirculating oil system.
