Summary, etc. Gas turbine engines have been used in power houses, ships and aircrafts in general for propulsion.<br/>They are extremely powerful for their size and have very high thermal efficiency. Large airliners<br/>and military aircrafts use turbofans while small scale aircrafts such as mini UAVs and ultralight<br/>jet still use turbojets which are not as fuel efficient as turbofans. The purpose of this research is to<br/>investigate whether a mini turbofan should be developed for UAVs or not. Would it be more fuel<br/>efficient than the similar sized-turbojet as is the case in large scale turbofans?<br/>For this purpose, a mini turbofan was developed by taking off-the-shelf turbojet, installed a fan on<br/>the turbojet via a secondary turbine and a gearbox. A K60-TP engine manufactured by KingTech<br/>was used. A fan was attached to the engine inside a shroud and mounted on a test stand. The engine<br/>was run at different throttle positions where the fan’s RPM, fuel consumption, and thrust were<br/>recorded. With the available data, the Thrust Specific Fuel Consumption (TSFC) was calculated<br/>and was compared to a turbojet of the comparable size and thrust.<br/>It was observed that the turbofan came out to be 38% more fuel efficient than the turbojet. The<br/>results indicate that a mini turbofan would be more economical to operate than a turbojet of its<br/>comparable size, hence development of mini turbofan engines for commercial purpose is desirous.<br/>Mini turbofans, if commercially produced, would eventually phase out mini turbojets currently in<br/>use.
