OMRE Bene
The MSRz Bene was a Hungarian two seat primary glider, first flown in 1952. By this time its competitor had been awarded a serial production order, so only one working Bene was ever completed. Design and development In 1948 the Hungarian National Flying Association (OMRE), which in 1951 became the Hungarian Aeronautical Association (MRSz), invited tenders for a two seat primary glider; the runner-up was a design from Hugó Nagy and Tibor Bánsági. In 1950 they submitted a revised version, named Bene after Lajos Benicky the designer of the MSrE M-30 Fergeteg. The Bene had an all-wood, two part high wing, ball-jointed together on a short pedestal above the fuselage. In plan there was a rectangular inner section, occupying about a third of the span, and trapezoidal, round-tipped outer panels with most of the taper on the trailing edge. Each half-wing were built around a straight main spar at about 33% chord and an auxiliary spar at 70% chord. All wing surfaces were plywood co ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Spoiler (aeronautics)
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which intentionally reduces the lift (force), lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to ''spoil'' the streamline flow. By so doing, the spoiler creates a controlled Stall (flight), stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from air brake (aeronautics), airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag. Spoilers fall into two categories: those that are deployed at controlled angles during flight to increase descent rate or control roll, and those that are fully deployed immediately on landing to greatly reduce lift ("lift dumpers") and increase drag. In modern fly-by- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1952
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

MRSz Z-03 Ifjúság
The MRSz Z-03A Ifjúság () was a Hungarian advanced training glider built in the 1950s, capable of both aerobatics, aerobatic and, with the revised Z-03B, blind flying instruction. They were removed from service in 1960 after metal fatigue, fatigue analysis revealed that the fuselage structure at the wing attachment point had only a short life. Design and development In 1948 Hungarian National Flying Association (OMRE), which in 1951 became the Hungarian Aeronautical Association (MRSz), invited tenders for a two seat primary glider. The Z-03 Ifjúság won the contract for 100 aircraft, with a design by Ferenc Zsebő capable of exploiting thermals and performing basic aerobatics. Its first flight was in February 1953. There were two production variants, the Z-03A and the Z-03B. The Z-03 had a wooden, single spar (aeronautics), spar mid-wing, mid-mounted wing which was trapezoidal in plan, with plywood covering ahead of the spar forming a torsion resistant D-box, and with fabric ...
