Specifications

Performance

Other

The paper Wing, so called because it used paper webbed ribs, first flew in 1929. Wingspan was later increased to 14.33 m. / 47.0 ft. principally by extending the ailerons. It was first U.S. built sailplane to fly for more than 1 hour. A replica of the Paper Wing belongs to the San Diego (CA) Museum of Flight. AS a footnote, a Bowlus design (or a copy), the Nighthawk, flown by William A. Cocke gained the world endurance record of 21 hr. 34 min in 1931. This glider is in the museum of flying, Santa Monica, CA

Specifications

Performance

Other

A development of the Bowlus Super Sailplane built by the Curtiss Wright Technical Institute in Glendale, CA in 1932, the senior Albatross had a slightly extended spar and gull wing. No two were completely alike, with flaps on at least one version. The design dominated the U.S. Nationals and held many U.S. records through the 1930ís. Senior Albatrosses were owned and/or flown by notables such as Warren Eaton, Richard du Pont and Chet Decker. Examples belong to the Smithsonian Air & Space Museum and the National Soaring Museum.


Bowlus BA-100 Baby Albatross

Specifications

Performance

Other

The Baby Albatross, which flew in 1937, was a production design for both kits and complete sailplanes. Bowlus produced kits until the oubreak of World War II in 1942, and in 1944 Laister-Kauffmann bought the rights but produced no aircraft before going out of business. The wing is reminiscent of the German Grunau Baby design, and the pod is a molded plywood unit. No spoilers are provided, but some have been modified by owners to provide them. Many other modifications were carried out, including one Baby with a steel tube pod built by Schweizer. Many soaring notables had a Baby Bowlus as their first ship, including Dick Johnson, Dick Schreder and Joe Lincoln, and flights of more than 402 km / 250 miles have been made. One example belongs to the National Soaring Museum. The Vintage Sailplane Association has plans. ATC.

The two-place Baby-Albatross was created by adding approximately two feet to the pod of the BA-100 Baby Albatross and providing for a second seat beneath the wing, with porthole windows on each side. The first built had the usual Bowlus control yokes while the second had conventional sticks. Those built up from BT-100 parts were known sometimes as the BTS-100. There are no approach control devices. One belongs to the National Soaring Museum. The Vintage Sailplane Association has plans.


Bowlus / Nelson Dragonfly

Specifications

Performance

Other

The Dragonfly was an early self-launching sailplan whose marketing was sponsored by the Nelson Engine Company as a vehicle for their two-cycle four cylinder engine. The result was an under-powered sailplane. The Dragonfly features a fully retractable tricycle landing gear with stearable nosewheel, dual control and a ratchet-wire pull starter in the cockpit for engine starts in flight or on the ground. Two examples belong to the National Soaring Museum.
