Marske Aircraft Corporation is a company of the German-born American Jim Marske (* 1938) in Marion, Ohio. The company specializes in the construction of tailless gliders and sells them mainly as kits.
XM1
Marske's first design, the XM-1, was made in 1957, inspired by the designs of Al Backstrom and Charles Fauvel . The wing profile of the AV 36 was used with a span of 11.6 m. The XM1 initially had side fins on the wing tips, but was then equipped with a central fin. It was controlled by elevons and flaps on the wing tips instead of a rudder. As a landing aid, expansion flaps were also available on the underside of the wing. The last modification, the XM1d, had a glide ratio of 24 at 82 km / h.
Pioneer
Marske's second design from 1968 was named Pioneer. The roll control was carried out via spoilers. Marske later commented that this was probably not his best idea to get a powerful glider. The successor Pioneer II got normal ailerons again and proved to be very efficient thanks to the very thin wing profiles used.
The Pioneer series continues to this day and with the Pioneer IV in 2016 the most powerful flying wing glider emerged. Profile development takes place in collaboration with John Roncz, who also designed special profiles for Burt Rutan .
Variants of the Pioneer series
Pioneer I.
- Equipped with roll spoilers instead of ailerons and with a wingspan of 12.2 m.
Pioneer Ia
- enlarged wingspan
- 1. Series version with normal ailerons and spoilers, 14 m wingspan. Profilstrak NACA 33012R on NACA 33010R.
Pioneer IIc / d
- Modified vertical tail unit with swept back, canopy embedded in the fuselage contour and partly new wing tips (15 m span) glide ratio> 35 at 95 km / h
- New model in fabric-covered all-plastic construction. Span 15 m, profile M35a with 12.7% thickness, glide ratio> 41 at 104 km / h
Pioneer IV
- Fuselage of the Pioneer III with wings in plastic shell construction and modified profile M 451 with 12% thickness. Glide ratio ≈48 at 115 km / h and 24 at 210 km / h
monarch
With the Marske Monarch, the company has also been offering an open, ultra-light glider in board-only wing design since 1974. As with the Pioneer II, the grand piano was originally made of wood. In the meantime, the GRP construction has been used. The fuselage is also made of GfK-AfK, the wings are covered with fabric. Wingspan 12.8 m, glide ratio 19 at 64 km / h. Empty weight in the Kevlar version 70 kg.
Group Genesis-Genesis 2
Marske is already working with aerodynamicist John Roncz, who also worked with Burt Rutan . This is how the Genesis 2 was born in 1995 , of which a total of 27 were manufactured by the LAK aircraft manufacturer in Lithuania.
