Powerplant

The Ju 52/3mg5e was powered by a trio of closely cowled 830 hp (619 kW) BMW 132T-2 9-cylinder air-cooled radial engines. The two outboard engines were 'toed-out', or in other words, were set at an angle to the main thrust line. This reduced the considerable yaw if one of the wing engines was lost, by pulling the aircraft away from the dead engine.

The nacelles housed the engine oil tanks above the wing leading edge. Filler caps above them served the oil (forward) and fuel (rear) tanks. The fuel was held in wing tanks, positioned inboard of the engines. Exhaust gas from the engines was collected by annular ducts and ejected below and to the sides of each engine. These caused characteristic stains on the fuselage and wings, but kept the filler caps and cockpit area clean. The 3mg5e introduced exhaust de-icing. (19a)

Junker JU 52 Versions

Junkers Ju 52/3m ge

The initial Ju 52 was a single-engine aircraft. Since it lacked performance, and the state of technology couldn't deliver higher performance engines yet, Junkers decided to add 2 additional engines, both mounted on the wing. The designation then received the '/3m'.

The seventh Ju 52 airframe was used for the first 3-engine prototype, powered by three Pratt & Whitney Hornet radials, rated at 550 hp (410 kW) each. A number of subversions were built for various (export) customers:

• Ju 52/3m ce: Version for A.B. Aerotransport of Sweden, Aero O/Y of Finland, and Deutsche Lufthansa. It had cowled engines and spatted mainwheels.

By 1932, the German airline, Lufthansa, had sufficiently recovered from the economic woes of the 1920’s to put in service a three-engine civil transport plane, the Junkers Ju 52/3m.Based on a short-lived single engine model, the Ju 52 first flew in April 1931 and quickly became the workhorse of both the airline and the reviving Luftwaffe, with a standard passenger-carrying load of 17. During the Spanish Civil War, the Ju 52 ferried more than 10,000 Moorish troops from Morocco to Spain, as well as dropping 6000 tons of bombs.
