|
| Built in the early 1970's the Budworth Puffin was a product of Budworth gas turbines LTD a British company based in Harwich england. Unlike the stationary engine this unit is clearly designed as a small propulsion unit. This design of engine proved troublesome and was redesigned when Noel Penny took over the company which then became Noel Penny Turbines. An extremely rare engine which may not have been produced in any significant numbers.
This engine was also used as a turbo shaft unit. The Puffin engine served as a gas generator which drove a power turbine. One application for this unit was as a blower for a hover craft. The shaft output was used to drive a small axial compressor which inflated a hover craft skirt. |
