Boeing Model 42
open-in-new
<h2 id="development-and-design">Development and design</h2> <p>The Model 42 was essentially an Airco DH-4M-1 fitted with new Boeing tailplanes, tapered wings, and tripod landing gear. The first aircraft built, designated XCO-7, was used as a static test bed, and did not fly. The second aircraft, XCO-7A, used a standard DH-4M-1 fuselage and Liberty engine, with the Boeing modifications. The final aircraft, XCO-7B, added balanced elevators and inverted the Liberty engine. Both flyable aircraft were shipped to <a href="/facts/McCook_Field/9SnhgfCN">McCook Field</a>, where the first flight occurred on 6 February 1925.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> </p><p>The performance of the new aircraft did not justify the cost of the conversion, and Boeing abandoned the project.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> <h2 id="specifications-xco-7a">Specifications (XCO-7A)</h2> <p><i>Data from</i> Bowers, 1966. pg. 60.</p><p>General characteristics </p><ul><li>Crew: 2</li> <li>Length: 29 ft 2 in (8.89 m)</li> <li>Wingspan: 45 ft 0 in (13.7 m)</li> <li>Height: 10 ft 8 in (3.25 m)</li> <li>Wing area: 440 sq ft (40.9 m2)</li> <li>Empty weight: 3,107 lb (1,409 kg)</li> <li>Gross weight: 4,665 lb (2,116 kg)</li> <li>Powerplant: 1 × <a href="/facts/Liberty_L-12A/G4wCoc6P">Liberty L-12A</a> , 420 hp (310 kW)</li></ul> <p>Performance </p> <ul><li>Maximum speed: 112 mph (180 km/h, 97 kn)</li> <li>Cruise speed: 110 mph (177 km/h, 96 kn)</li> <li>Range: 420 mi (676 km, 360 nmi)</li> <li>Service ceiling: 13,050 ft (3,977 m)</li></ul> <p>Armament </p> <ul><li>4x 0.30 cal machine guns</li></ul> <ul><li>Bowers, Peter M. <i>Boeing aircraft since 1916</i>.
