The Swallow New Swallow is a biplane that was built by the American Swallow Airplane Manufacturing Company in the 1920s .
development
The Swallow Airplane Manufacturing Company was formed in 1923 through a reorganization of the EM Laird Company in Wichita (Kansas) after the founder EM Laird left the company. The main shareholder was still "Jake" Moellendick , Walter Beech was appointed to be responsible for all field services, while Lloyd Stearman was promoted to chief designer. Stearman's first assignment was the construction of the New Swallow to replace the Laird Swallow .
The New Swallow, presented in 1924, was overall slightly smaller than the Laird Swallow and differed mainly in the wing structure, which was now only single-handled instead of two-handled as before. This mainly served to simplify maintenance and operation. The three-seater double-decker also differed from the earlier Swallow in that it had a fully encased engine and a single-axle chassis.
About fifty units were made before the design was improved in 1926. The introductory price was 3,500 dollars and was the end of 1926 reduced to 2485 US dollars.
In 1927, the Swallow OX-5 designed by Waverly Stearman was introduced. Their wings had a USA-27 profile and N-shaped struts. The New Swallow's Curtiss OX-5 engine was retained. Many Swallows were later upgraded with more powerful engines such as the Wright J-5 with 225 PS (165 kW) or the Continental R-670 .

use
The three-seater Swallow was used by both small businesses and newly established regional airlines such as Varney Air Lines . The airlines used the planes to transport mail on the recently introduced airmail routes . Few of the machines that have been upgraded with more powerful engines still exist. One of them is stationed at Wittman Regional Airport in Oshkosh , Wisconsin , and is used there for commercial sightseeing flights.
