Jurca MJ-51 Sperocco
The Jurca MJ-51 Sperocco (Special Sirocco) is a plans-built two-seat tandem aerobatic aircraft derived from the Jurca MJ-5 Sirocco. Design and development Encouraged by friends and previous customers, Marcel Jurca developed the MJ-51 in 1969 as an improved, higher power Sirocco. It has a longer, more rounded, stronger fuselage capable of engines up to and the wings of the MJ-7 Gnatsum without dihedral. Other changes include a raised rear seat, a longer canopy and a smaller tail. Jurca said that it was his favourite two-seat design. There are two variants - the MJ-51B for engines of , and the MJ-51C for engines from up to . Three examples have been started, each varying from the basic design in collaboration with Jurca himself. Construction of the first prototype started in France in around 1981. It was to be powered by a Lycoming AEIO-360. The builder died in 2004 and the project remains incomplete. The second example was started in the USA in 1991. It has a Lycoming IO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marcel Jurca
Marcel Jurca, (1921 – 19 October 2001) was a prolific designer of homebuilt aircraft in France. He is most well known for his Tempête and Sirocco designs. Early life Born in Romania, Jurca was impressed by the PZL fighters which often flew over him. He learned to fly in a Grunau 9 primary glider while studying engineering. Having joined the Royal Romanian Air Force in 1940, he flew the Henschel Hs 129 in 1943-1944. He moved to France in 1948. After a period as a volunteer flying instructor on the Stampe et Vertongen SV.4, he worked in industry, including 15 years as a commercial director, and retired in 1983. He was naturalised French in 1965. Aircraft design On moving to France, he missed having an aircraft to fly, so he created his own. His first attempt at aircraft design was the MJ-1, which he considered unsatisfactory. He then built a Jodel D-112 with the help of the Aéro-Club de Courbevoie at Saint-Cyr-l'École. It flew in 1954. Then, inspired by the Piel CP-40 Donal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurca Sirocco
The Jurca MJ-5 Sirocco (named for the Sirocco wind) is a two-seat sport aircraft designed in France in the early 1960s and marketed for homebuilding. It is one of many wooden homebuilt designs from Romanian born designer Marcel Jurca. Jurca, a Henschel Hs 129 pilot in World War II marketed the plans in Canada and America through Falconar Aviation. It is a low-wing cantilever monoplane of conventional configuration and wooden construction throughout. The tandem seats are enclosed by a bubble canopy, and the tailwheel undercarriage can be built as either fixed or with retractable main units. Marcel Jurca died on 19 October 2001, at which time plans were still available from the designer's web site. Plans are supplied by Avions Marcel Jurca and Manna Aviation of Australia.

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurca Gnatsum
The Jurca Gnatsum is a French homebuilt near scale replica aircraft based on the North American P-51 Mustang. Design & Development The Gnatsum (Mustang spelled backwards) is one of many wooden homebuilt designs from Romanian designer Marcel Jurca. Jurca, a Henschel Hs 129 pilot in World War II, expanded his warbird replica designs to include the Allied North American P-51 Mustang fighter. The Gnatsum is a low-wing, cantilever monoplane with an enclosed single-seat cockpit and manually retractable tailwheel landing gear based on that of the Jurca Sirocco. Suitable for a number of engines around , plans for the Gnatsum are available as the 2/3 scale MJ-7 and the 3/4 scale MJ-77, as well as the MJ-70 full-size representation. All versions are constructed from wood with fabric covering, and manufacturing rights to the kit aircraft were acquired by Falconar Avia. Plans for the MJ-77 are available from Avions Marcel Jurca. Some of the engines suitable for the MJ-7 Gnatsum series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihedral (aeronautics)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
