Type Turboshaft
National origin United States
Manufacturer Boeing
Major applications QH-50 DASH
Developed into Boeing T60

The Boeing T50 (company designation Model 502) was a small turboshaft engine produced by Boeing. It was the first turboshaft engine to ever power a helicopter: a modified Kaman K-225 in 1951. [1] Based on Boeing's earlier Model 500 gas generator, the T50's main application was in the QH-50 DASH helicopter drone of the 1950s. An up-rated version designated Model 550 was developed to power the QH-50D and was given the military designation T50-BO-12.

Two T50 were tested on a HTK-1 (Kaman HH-43 Huskie) in the 1950s, which was the first test of twin turbine engine on a helicopter. [2]
