Mississippi State University XV-11 Marvel

TerryLeave a comment

Students and researchers at Mississippi State University in Jackson built and flew the XV-11 Marvel in 1965 to test boundary layer and STOL technology. The name M.A.R.V.E.L. stood for “Mississippi Aerophysics Research Vehicle with Extended Latitude”.

The first all-composite aircraft, it carried out its initial program of research on behalf of the US Army in the late 1960s, and was rebuilt in the 1980s as a proof-of-concept for a utility aircraft.

The Marvel is now on permanent display at the Southern Museum of Flight at the Birmingham International Airport in Alabama.

Mission Aircraft Morrison 6 / Barr 6

TerryLeave a comment

The airframe is designed around the efficiency of the 8 cyl Lycoming engine the engine prop combination produces a balance of objectives that allows speed, service and the freedom of no flight restrictions.

All skins of the Morrison 6 kit are made with 7781 e-glass prepreg and epoxy resin content of 36 to 38 %, vacuumed bagged and cooked at 250 degrees, plus the fibers in the prepreg stay in a straight line making for a stronger skin. Nomex core wrapped in adhesive. Designed for ease of assembly. Pre-cured graphlite carbon rod packs are built into the structure to carry the designed loads. The advantage of the rods is that the fibers in the rods are straight and will test out to the tinsel strength designed.

Canada
Formed in Montreal by Bernard C. Maranda to develop and manufacture ultralight aircraft, acquiring worldwide license for Adam RA-14 and RA-17 high-wing monoplanes from French designer Roger Adam in 1957. These marketed as RA14BM1 and BM3. Also developed Hawk BM4, based on Beam Minicab, and Lark BM6 single-seat aerobatic biplane.

Mirage Aircraft Marathon

TerryLeave a comment

The Marathon is a high performance, 2-place side-by-side plans built airplane with fixed tricyle landing gear. Constructed primarily of wood and fiberglass covering, the Marathon cruises at about 185 mph range on 150hp and has a range of over 900 miles. Engines range from 150 to 180hp.

The builder has the choice of carrying all the fuel in the wing, or sleek tip tanks can be installed.

Complete landing gear assemblies and other finished components were available from Mirage Aircraft. Six construction videos are also available.

The complete set of plans, videos, and construction manual guide you through the project, teaching you the skills as you go.

The Marathon is patterned after the Celerity, which was designed by Larry Burton.

Engine: Lycoming O-320, 150 hp
Cruise: 185 mph

Mirage Aircraft Celerity

TerryLeave a comment

The Celerity was designed by Larry Burton, who flew the prototype in 1985 and won an Oshkosh workmanship award that same year. The prototype has accumulated over 900 hours. It is designed to be built by the average person, with average skills, at low cost, yet perform as well as the most expensive kit airplanes in it’s class.

The Celerity is a high performance, 2-place side-by-side plans built airplane with fully retractable landing gear, including the tail wheel. It can also be built as the “Marathon” with fixed tricycle gear. Designed for builders with average skills, both aircraft are constructed from wood with fiberglass covering. Six construction videos were available. Celerity cruises in the 200 mph range on 150 to 180 hp and has an operating range of more than 750 miles with fuel reserve. The builder has the choice of carrying all the fuel in the wing, or sleek tip tanks can be installed.

Mills Special (N520ET c/n JM-12)

This original design high wing light plane was designed by Jerry Mills, who started the construction in 1978. After the death of designer the construction was continued by Edward J. Thomason and James Smith of Calhoun, Georgia, USA. Registered N520ET on May 9, 1994, the aircraft was first flown a year later, May 20, 1995. The one-of-a-kind single-seat aircraft, nicknamed Puddle Jumper, has a 150 hp Lycoming O-320-E2D engine, and features a mixed steel/aluminium (fuselage) and wood/fabric (wings) construction. On July 28, 2005, the aircraft was registered to Jack Hurdle of Senoia, Gerogia.
