The R-985 Powered de Havilland Beaver: Arguably the Best Bush Plane Ever Built

With a big, nine-cylinder Pratt & Whitney strapped to the front, this 5,100-pound workhorse boasts a useful load of around 2,000 pounds, and it’s built to operate out of short and rough airstrips.

The Radial Engine: There’s No Beating a Classic

When it comes to airplane engines, radial engines are the true classic

radial aircraft enginesEver since Louis Bleriot crossed the English Channel in 1909, the radial engine has been an integral part of modern aviation.   Their simple yet powerful design has been improved upon throughout the 1900’s, but the basic principles behind the airplane engine have remained constant. Pratt and Whitney R-985 and R-1340 radial engines were designed starting in the 1920’s, and have withstood the test of time.  Many of these radial engines are still in use today, thanks to companies like ours who are able to perform the overhaul and maintenance required for these masterpieces.

The R-1340 radial engine was Pratt and Whitney’s first foray into airplane engines, and approximately 35,000 engines were produced.  The next engine to be mass-produced was the R-985.  This engine was manufactured from the 1930’s to the 1950’s, and over 39,000 of them were made

Radial engines played a major part in the First World War, outlasting and outperforming rotary engines over time.  The R-985 and R-1340 engines became the standard aircraft engine for World War II, powering airplanes used in basic training as well as military versions of civil aircraft.  After the war, R-985 engines were used in various smaller civil and military airplanes, including utility aircraft, small transports and agricultural aircraft.  Their simple design and reliability made them popular among airplane enthusiasts around the country.

Today, you’ll find most R-985 and R-1340 engines in bush planes and agricultural aircraft, as well as on WarBirds.  Parts for these engines are still available on the market, but repair and overhaul of R-985 and R-1340 radial engines requires a skilled technician.  As a certified FAA Repair Station, our Radial Engine Division is the largest R-985 and R-1340 overhaul facility in the world, and we pride ourselves on being true artisans when it comes to overhaul and maintenance of radial engines.

So, if you’ve got a plane with one of these engineering marvels, be sure to entrust its maintenance to a facility that specializes in the radial engine.  They can keep your engine running for years to come.

What is the Pratt & Whitney R-1340 Wasp & List of R-1340 Powered Aircraft

The Pratt & Whitney R-1340 Wasp was a 9 cylinder, single-row, air-cooled radial engine with horsepower ranging from 410 hp to 600 hp, depending on the model and configuration. It was used in a range of aircraft that included the North American AT-6, Boeing P-26, and Boeing 247. Jimmy Doolittle used the Wasp to set records in his Gee Bee Racer and Amelia Earhart made history using the Wasp in her Electra L-10.

Geico Skytypers’ North American SNJ-2 Team to Appear at 2017 Mid-Atlantic Air Museum WWII Weekend

GEICO Skytypers Airshow makes first appearance at popular World War II event.

The Mid-Atlantic Air Museum is pleased to announce that the GEICO Skytypers Airshow Team — a six-ship aerobatic team flying the North American SNJ-2 — will perform at the Museums 27th Annual World War II Weekend set for June 2-3-4, 2017.

The GEICO Skytypers Airshow Team will perform an 18-minute low-level flying demonstration each day of the show.

“This is an exciting first for World War II Weekend“, said Museum President Russ Strine, “as this is our first ever six-ship formation team”.

The GEICO Skytypers Airshow Team will also “skytype” around the local area all three days of the event.

The North American SNJ-2 is a single-engine advanced trainer aircraft. Powered by a 550hp Pratt & Whitney R-1340-56 engine, the Depression-era SNJ-2 was designed to United States Navy specifications.

The Mid-Atlantic Air Museum is located at the Reading Regional Airport in Reading, Pennsylvania. For more information about this year’s event, visit the MAAM WWII Weekend.
