The Taylor Chummy was a light utility aircraft made by the Taylor Aircraft Company in the late 1920s. It was the fore-runner of the highly successful Piper Cub series.[1]
Design and development
The Chummy was designed by brothers Clarence Gilbert Taylor and Gordon Taylor in 1928.[1] It is a braced, parasol-wing monoplane with two seats side-by-side in an open cockpit.[1] Power was supplied by a tractor-mounted radial engine.[2] Fixed, tailskid undercarriage was fitted, initially with a through-axle, but later with divided main units.[3] The name "Chummy" was chosen because of the side-by-side seating.[2]
Operational history
The first B-2 prototype was rebuilt with a seven-degree variable-incidence wing for entry into the Guggenheim Safe Airplane Competition under the designation C-2.[4][5]
The Chummy was expensive and did not sell well, leading to the bankruptcy of the Taylor Brothers company in 1930 after only eight aircraft were built.[4][5]
Variants
- A-2 Chummy
- Two prototypes through-axle main undercarriage.[3][6] The first, construction number (c/n) 3, was designated Arrowing A-2 Chummy and was powered by a 90 hp (67 kW) Anzani radial engine.[2][3] The second, c/n 4, was designated Taylor A-2 Chummy and was powered by a 96 hp (72 kW) Ryan-Siemens engine.[6]
- B-2 Chummy
- Refined version based on the A-2 with divided main undercarriage.[3] Originally offered with a 90 hp (67 kW) Kinner K-5 or 96 hp (72 kW) Ryan-Siemens Yankee 7 engine, though the latter option was later replaced with a 90 hp (67 kW) Brownbach Tiger engine following the completion of the first production aircraft.[2][3][7] Two built; two prototypes (c/n 7 and 8) and four production aircraft (c/n 9, 12, 13, and 14), all powered by Kinner engines.[7] Several aircraft had their construction numbers changed after completion; the unflown second prototype (c/n 8) became c/n 10 while the third production aircraft (c/n 13) became c/n 15.[8]
- C-2 Chummy
- The first prototype B-2 (c/n 7) rebuilt with a variable-incidence wing and assigned a new construction number, c/n 10.[5]
Accidents and incidents
On April 24, 1928, Gordon Taylor crashed A-2 Chummy prototype c/n 4, registered X4901, at an exhibition at Ford Airport in Dearborn, Michigan.[9][10] His passenger, Aaron Rosenbleet, was killed instantly, and Taylor died of his injuries shortly after reaching hospital.[9] Clarence Taylor witnessed the crash.[9]
Replica
A Taylor Chummy replica is on display at Greater Rochester International Airport.[11]
