Titan trivia

One of the first designs penned by the original Solar Company, way back in the late 1950's or early 1960's(?) The Titan has been produced in may different configurations and intended uses. Electrical power generator, Mechanical drive, Starting unit for bigger turbines, Home built aircraft, (Fixed wing and rotary.) ect. Today they are popular amongst hobbists, as they are readliy available, inexpensive and easy to run. The Titan was made from 60 Horsepower, all the way up to 165. Basically a big turbocharger, with a combustor can tacked on the side, the compressor is a single centrifugal flow unit, and the turbine a single radial inflow type. (Yes, just a big turbo.)
The main caveat with these units is they were originally designed to be single speed engines, operating at 100%. If run off-design speed, the turbine wheel, which is a one-piece casting, may excite in it's first design flexural frequency, and fail rather spectactularily. If this is in a homebuilt aircraft, the results have been deadly. So, a word of advice, if you are contemplating using a Solar Titan in a homebuilt aircraft, make sure you have provisions in place to run the unit steady-state at 100% speed, via a variable pitch prop, constant speed drive, CVT, or other.

The most popular homebuilt engine is a bit of a hybrid. Using the T62-32 core engine, (The highest rated horsepower unit @165.) mated to the low output engine gearbox assembly, for reduced weight. (The -32 gearbox is a bit of a pig, weight wise.)

Seen one of these in a jet-ski once.
