He inducted the Trident Passenger Jet Airplane to Air Ceylon thus taking Air Ceylon from a propeller driven era to a Jet engine era.
The propeller was driven directly from the crankshaft via the gearbox using a 2:1 gear-reduction ratio which enabled the engine to operate at full power while accommodating the operational requirements of the propeller which necessitated the slower maximum rotational speed of 1800 rpm.
A new arrival is the Belgian D-Motor LF26, a compact 2.7-litre flat-four aero-engine that has direct drive to a propeller, rather than a reduction gearbox.
All were armed with six 7.92 mm (.312 in) MG 17 machine guns — four synchronised weapons, two in the forward fuselage and one in each wing root, supplemented by a free-firing MG 17 in each wing, outboard of the propeller disc.
This unremarkable and derivative design was, however, transformed into a formidable fighter when it was fitted with the newly developed synchronizer gear, the Fokker Stangensteuerung, firing a single 7.92 mm (.312 in) Parabellum LMG 14 or Spandau lMG 08 machine gun through the spinning propeller.

The company offered charter services in Pakistan under the name JS Air, using a small fleet of propeller driven Beech aircraft with a maximum capacity of about 20 passengers.
Armament consisted of two 7.7 mm (.303 in) Type 89 machine guns, synchronized to fire through the propeller.
On 25 October 1979, Vickers Viscount G-BFYZ of Alidair was damaged beyond economic repair when the aircraft departed the runway after #4 propeller struck the runway.

In the 1974/75 season during an open field takeoff on Dome C a JATO bottle on an LC-130F came loose and damaged the wing and one propeller thus causing an aborted takeoff.
The Lockheed Model 8 Sirius was a single engine, propeller-driven monoplane designed and built by Jack Northrop and Gerard Vultee while they were engineers at Lockheed in 1929, at the request of Charles Lindbergh.
In mid-1935 Lockheed's chief engineer, Hall Hibbard, began discussing with Al Menasco, the president of the Menasco Motors Company in Burbank, the merits of coupling two Menasco C6S Super Buccaneer six-cylinder in-line engines mounted side-by-side, driving a single propeller.
British"?title=Vickers machine gun">Vickers or 7.9 mm Hotchkiss) which used the deflector wedges, first demonstrated on the Morane-Saulnier Type L, in order to fire through the propeller arc.
Although the screw propeller had been added to an engine (steam engine) as early as the 18th century in Birmingham, England by James Watt, the petrol engine only came about in the later part of the 19th century, at which point Frederick William Lanchester recognized the potential of combining the two components to create the first all British powerboat; tested in Oxford, England, the powerboat was born.
Beechcraft T-34 Mentor - a propeller-driven, single-engined, military trainer aircraft derived from the Beechcraft Model 35 Bonanza.
Since the inside of the propeller is moving slower than the outside, the blade is progressively more swept toward the outside, leading to a curved shape similar to a scimitar - a practice that was first used as far back as 1909, in the Chauvière make of two-bladed wood propeller used on the Blériot XI.
