P-51 Mustang Takes Flight With Modern Prop Technology

A P-51 Mustang has been flown with a new, 4-bladed composite prop. On Thursday, MT Propeller distributor Flight Resource, LLC announced the successful flight testing on a newly developed 4-bladed composite propeller to be utilized on the Allison powered P-82 Twin Mustang. This propeller, governor and accumulator system was designed and built including a control system for use on the only two remaining Twin Mustangs  that are being restored to flying condition. 

MT-4B Prop On A P-51 Mustang

The 11 foot diameter, 4-blade propellers include full feathering capability and still maintain the period look of the original steel propellers, using MT's patented natural composite structure. The hub is CNC milled from a single billet of aluminum. The governors were designed from scratch and the spinner is Kevlar. 

The prop was mounted and flown on a P-51 Mustang (Polar Bear) for five successful flights in December. Initial results indicated improved climb and cruise performance over the metal 3-blade prop that normally pulls this P-51.  The propeller and governor will now undergo the vigorous testing required to complete FAA  & EASA certification.

MT-Propeller says it is no stranger to the design and manufacture of replica propellers. Several rare aircraft continue to please airshow and air racing fans sporting MT-Propellers.
