Motorer som var i populär användning under spannet av dessa verk var oerhört många och varierade. Precis som med flygplansbyggare var det en tid som var helt gratis och krävde experiment, omvandling av vad som var användbart och ren uppfinning. Några som föddes tidigt i denna tid är fortfarande kvar, men de flesta är historia. Med undantag för utländska motorer betjänade dessa poster de flesta fallen. AeroFiles täckning av jetmotorer är för närvarande under utveckling, och preliminärt arbete kan ses här. Särskild kredit och tack går till Clyde Bishop, som nyligen släpptes med en underbar gammal bok, 1921 Airplane Engine Encyclopedia av Glenn Angle, fylld med information om tidiga powerplants151 som vi aldrig någonsin hört talas om De flesta av de gamla grafikmotorerna sett här är från den treasuryen.

Motorerna, varav flera av de större delarna var vanliga för standardmotorer, byggdes i direktdrivna och versioner. IVD hade ett inlopp och kröp runt cylindrarna för att hjälpa luftkylning. IVG hade dessutom en växeldriven fyrbladig fläkt i en cirkulär öppning vid det reviderade inloppet till den här kabinen för ytterligare kylningskapacitet. IVG var tydligen den modell som installerades i Crouch-Bolas Dragonfly. Övergripande, enligt min mening, var Dragon-motorerna, tillsammans med Dragonfly-flygplanet, ett viktigt, välutvecklat tidigt steg i utvecklingen av STOL-kapacitet. De verkar ha kommit fram till motorairframe-kombinationen på ett sätt som idag skulle kallas ett systemtekniskt tillvägagångssätt.

To demonstrate its capability to military and civil aviation officials in 1940, a 1500-mile flight from Dallas to Washington DC took 10h:35m flying time at an average 142mph. Cruising at 3000 altitude at 1800rpm on Caterpillar tractor fuel (6 cents a gallon) consumed at the rate of 11.5 gph, cost was only 6.90. Three gallons of lubricating oil added 4.20151a total of 11.10 for fuel and oil for the flight. Its fuel cost of less than 12 cents a mile was an unheard-of figure for flight operations at the time C - c.1942 - This 6HOA was built for a military contract during the war as a drone engine. It was a C-series 6-cylinder with A-series cylinders and pistons and was used, as I remember, on the twin-engine Interstate Target Drone.

Two main shafts emerged for coaxial propellers, and there was a two-speed gear-change box between the crankshaft and the propeller shafts. XR-7755 was born in the summer of 1943, but with the end of World War II in 1945, the military no longer had use for an engine this size, and development ended.

While not the first radial aircraft engine151that was an operating six-cylinder with two banks of three cylinders and a double-throw crankshaft built in 1913 by J W Smith in Cicero IL151the Pratt Whitney was certainly the most successful. When Frederick B Rentschler and a group of Wright engineers left that company and formed their own group in 1925 to produce the nine-cylinder R-1340 Wasp, they had neither official organization nor name when the prototype was submitted to USN for evaluation. The very un-aviation Pratt Whitney Machine Tool Division of Niles-Bement-Pond Corp (Hartford CT) had made castings for the prototype and cast its name in the metal housing. Navy evaluators dutifully transcribed this name into their records and a company was born, even though there was no actual connection with the original tool manufacturer. The first Wasp (410hp), designed by George Mead and Andy Willgoos, was completed on Christmas Eve 1925, passed USN tests in March 1926, and a Boeing F2B-1 was selected as the first operational plane to use the new motor.

R-2180 Twin Hornet A c.1950 experimental 1150hp twin-row 14RA for prototype DC-4 only one built. The original R-2180 had a bore of 5.75 and a stroke of 6.0, and so a displacement of 155.8ci per cylinder, with 14 cylinders in two rows of seven each. R-2180 received the US Engine Type Certificate 196 on 51538. Besides the DC-4E prototype, it powered two Army prototypes, North American XB-21 and Stearman XA-21. Continued development of the engine was halted so that PW could concentrate on the R-2800 (18-cyl in two rows) and R-4360 (28-cyl in four rows), which both used cylinders of the same dimensions as R-2180, but were capable of much higher performance for use in WW2. After the war PW re-introduced the R-2180 and called it the Twin Wasp E1 as the largest member of their well-known Twin Wasp family, besides R-1830 and -2000. The R-2180, in its postwar form, received TC257 c.1948. It powered the Swedish SAAB-90 A2 Scandia twin-engined transport, apparently its only civilian use. A military version of R-2180 powered the prototype Piasecki H-16 heavy-lift helicopter. In a certain sense then the R-2180 Twin Hornet A led to both the R-2800 and the R-4360, but in its second life R-2180 was truly 12 of the R-4360. In the 10 years between certification of the Twin Hornet A and the Twin Wasp E1, there had been major developments in all aspects of piston-engine technology. Therefore, the Twin Wasp E1 must have been quite different in all details from the Twin Hornet A and probably bore little resemblance other than for the same bore and stroke.
