At last, after several false starts in the last 6 months or so, (and 2 hours late today!) the Hercules Propeller, donated by Dowty Propellers, has arrived and been sited outside the south east corner of the hangar, next to the Safran undercarriage display.
Many thanks go to John Benson for supervising the siting of the purpose built stand, on the newly prepared gravel area.
This propeller was designed and manufactured by Dowty Propellers for the Lockheed Martin C-130J Hercules Aircraft.
Dowty Propellers’military heritage stretches back to 1937 and encompasses many iconic military aircraft as well as front-line airlifters of today.
The R 391 propeller first flew on the C-130J in 1996, and entered service with the RAF in 1999. Its six thin ‘scimitar’ blades are made ofcomposite materials, mainly carbon and glass fibres, with polyurethane foam filling.
It is still in production, with over 2000R 391 propeller systems made to date.
The C-130J is a major update of the C-130 Hercules. The Hercules family has the longest continuous production run of any military aircraft in history. During more than 60 years of service, it has participated in military, civilian,and humanitarian aid operations throughout the world.
As of 2018,over 400 aircraft have been delivered to 21 operators.  Along with the Rolls Royce AE2100 D3 engines, the R 391 provides the C-130J with performance increases of: 40% range, 21% speed, 21% shorter take-off distance, and lower noise levels.
