SZD-50 Puchacz
The PZL Bielsko SZD-50 ''Puchacz'' (Polish: "eagle owl") is a Polish two-place training and aerobatic sailplane. Development The Puchacz was designed by Dipl-Ing Adam Meus based on the prototype SZD-50-1 Dromader. It was intended to serve as the successor to the popular Bocian for training. Its first flight was April 13, 1979. Being a moderately-priced, versatile, modern two-seater with good handling qualities on the ground and in the air, the Puchacz has become a very popular two-seater sailplane in many countries both for ''ab-initio'' and aerobatic instruction. A large number of fatal accidents involving spins have occurred with the Puchacz. Investigations have failed to uncover a common design flaw, but the type's reputation has nevertheless been tainted. Its supporters point out that it was designed to obey faithfully all control inputs - including foolish ones. Partial failures at the rudder bar and control sticks have been known to occur, but Airworthiness Directives hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Aircraft First Flown In 1979
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 ...

Cruciform Tail Aircraft
Cruciform is a term for physical manifestations resembling a common cross or Christian cross. The label can be extended to architectural shapes, biology, art, and design. Cruciform architectural plan Christian churches are commonly described as having a cruciform architecture. In Early Christian, Byzantine and other Eastern Orthodox forms of church architecture this is likely to mean a tetraconch plan, a Greek cross, with arms of equal length or, later, a cross-in-square plan. In the Western churches, a cruciform architecture usually, though not exclusively, means a church built with the layout developed in Gothic architecture. This layout comprises the following: *An east end, containing an altar and often with an elaborate, decorated window, through which light will shine in the early part of the day. *A west end, which sometimes contains a baptismal font, being a large decorated bowl, in which water can be firstly, blessed (dedicated to the use and purposes of God) and th ...

PZL Aircraft
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, these ma ...

1970s Polish Sailplanes
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Schleicher ASK 21
The ASK 21 is a glass-reinforced plastic (GRP) two-seat glider aircraft with a T-tail. The ASK 21 is designed primarily for beginner instruction, but is also suitable for cross-country flying and aerobatic instruction. Design and development The ASK 21 was designed by Rudolf Kaiser to replace the popular ASK 13, providing a modern two-seat aircraft bridging the gap between initial training and single-seat performance flying. The ASK 21 is the first full-GRP two-seater produced by Schleicher, flying for the first time in February 1979 (6.2.1979). Production also began in 1979, remaining in production to this day (May 2018), over 900 units completed. In December 2004 the ASK 21 Mi, a self-launching version, made its first flight. In 2003 the operating time was extended to 18,000 hours A revised and improved version, the ASK 21B was introduced in 2018. Construction The two seats are in a tandem arrangement with dual controls, adjustable rudder pedals and seatbacks. The fuselage c ...

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] |
