One of Many Garber Engine Storage Buildings

One aim of the new Udvar-Hazy Center is to display more of the engines that are now in storage.

Another Garber Engine Storage Facility

The National Air and Space Museum has over 500 engines in its collection, not including ones that are attached to aircraft.

Allison V-3420-23 (V-3420-B10)

Used in the Fischer XP-75, power is transferred to a contra-rotating propeller via two drive shafts that pass through the cockpit to the front mounted propeller reduction gear.

Continental XR-1740-2

This 14-cylinder single-sleeve-valve engine was one of several attempts by Continental to sell the sleeve valve concept.

Lawrance L-3

In 1914, engineer Charles L. Lawrance became interested in the development of air-cooled aircraft engines. After considerable research, the Lawrance Aero Engine Corporation of New York, New York, began to manufacture two-cylinder models on a small scale. These included the Models A-3 and N-2. The first of the three-cylinder designs was the Model B built originally in 1916. It was a three-cylinder radial engine with power ratings progressively improved from 35 to 60 hp. This led to a follow-on series of three-cylinder radials, the L-2, L-3, L-4, and L-5. Continuing the development of his air-cooled engine designs, Lawrance later developed his Model R and then the famous Model J series of engines. As a result of Wright Aeronautical's acquisition by merger of the Lawrance Company in 1923, the J series were eventually designated Wright Whirlwinds.

The U.S. Army and Navy purchased a number of Lawrance L-2 engines, which developed 60 shp. The L-3 was an improved version of the L-2.

Lycoming XR-7755-3

This 5,000 hp engine was intended to power the Convair B-36.

Napier Nomad Model E.145

A 12-cylinder two-stroke turbo-compounded Diesel, the Nomad was one of the most complex and fuel-effecient engines ever built.

Taft-Pierce-Loughead V-8

This engine was designed by Victor Lougheed, elder brother to Allan and Malcolm Loughead, founders of the Lockheed Aircraft Company. Lougheed designed and built the engine in 1911 and the Taft-Pierce Manufacturing Company of Woonsocket, Rhode Island, manufactured it. It was made almost entirely of Krupp chrome nickel steel at a cost of $15,000, the crankcase and cylinders being turned from solid billets weighing approximately 2,000 lb.

Fuel and lubrication were forced into the cylinders through bypasses in the sides of the cylinders and pistons. The multiple system of poppet valves, of which there were six in the head of each power-producing cylinder, provided for excellent and rapid scavenging of combustion gases. The eight air pumps, projecting from the lower part of the crankcase, maintained in the crankcase at all times a compression of air which was expelled through the cylinders on the exhaust stroke, and assisted in keeping the cylinders cool. 60 hp from 140 cu in and 81 lb.

Wright XR-2120

The last in a series of "Hex" engines, the XR-2120 was an unusual two-row radial with six cylinders per row.
