AiResearch GTC 43/44

The Airesearch GTC43/44 is a significant piece of Garrett's history. It was the first successful gas turbine produced by Garrett and was also the first small gas turbine to pass the 200 Hours  endurance test. The twin can combustor unit is very similar to its more commonly known derivative GTP70 which produced shaft power rather than compressed air. The first 43's were contracted to come in two variations , a self contained universal ground based support unit and a compact APU for aircraft (Both variations seen below).
