Ross-Johnson RJ-5
The Ross-Johnson RJ-5 is a single seat competition glider that was designed by Harland Ross and constructed partially by Ross and finished by Dick Johnson. The RJ-5 became one of the most famous gliders ever built when Johnson flew it in 1951, setting a new world distance record that endured for 13 years.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 60. Soaring Society of America, November 1983. USPS 499-920 Design and development The RJ-5 was conceived by Johnson, who contracted Ross to design and built a glider with record-setting performance. The aircraft utilizes a NACA 63 (2)-615 laminar flow airfoil and was one of the first gliders to achieve a 40:1 glide ratio. Johnson asked Ross to build the RJ-5 in 1948. Ross completed the design work and much of the construction, with help from Stan Hall, but by 1950 the glider was still incomplete. Johnson took delivery of it, finishing work on it at Mississippi State University, and incorporated some design chan ... [...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".

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] |
1950s United States Sailplanes
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support. Severus marches to Mesopotamia to battle the Parthians. * The Roman province of Syria is divided and the role of Antioch is diminished. The Romans annexed the Syrian cities of Edessa and Nisibis.

Oldershaw O-2
The Oldershaw O-2, officially registered as the ''Oldershaw Jana-Linn O-2'', is an American high-wing, single seat, V-tailed glider that was designed and built by Vernon Oldershaw.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 51. Soaring Society of America November 1983. USPS 499-920 Design and development The O-2 was designed by Oldershaw to compete with Dick Johnson's Ross-Johnson RJ-5. The O-2 is constructed of wood. Its span wing employs a NACA 63 (3)-618 airfoil at the wing root, with a NACA 63 (2)-615 at the wing tip. The wing is equipped with dive brakes. The landing gear is a retractable monowheel. Only one O-2 was built. Operational history The O-2 first flew in 1961 and was flown by Oldershaw in the 1962 and 1962 US Nationals. The aircraft has made a number of flights in excess of , including one of . Oldershaw later sold the aircraft to Don Gaede of Torrance, California and it was reportedly still being actively flown in the 1980s. Gaede remod ...

Slingsby Skylark 4
The Slingsby T.50 Skylark 4 was a British single seat competition glider built by Slingsby Sailplanes in the early 1960s. It sold in numbers and had success at national, though not world level competition. Development The Slingsby Skylark 4 is the final development of the Skylark series of gliders and was first manufactured in 1961 using an 18.2m span wing similar to that of the Skylark 3. About 30 Skylark 4s are still flying today (2010). Slingsby had introduced double curvature fuselage panels made of glass reinforced plastic (GRP) into their previous design, the T.49 Capstan and they remodelled the front of the wooden fuselage of the Skylark 3 in this material for the Skylark 4, introducing a reclining pilot's position and smoother canopy line. Though the previous wing planform, span and area was retained, its ailerons were extended to increase the rate of roll and the outer panels used a different airfoil section, the more cambered NACA 6415, to give a better lift dis ...

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 ...

Dive Brake
Dive brakes or dive flaps are deployed to slow down an aircraft when in a dive. They often consist of a metal flap that is lowered against the air flow, thus creating drag and reducing dive speed.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 168. Aviation Supplies & Academics, 1997. In the past, dive brakes were mostly used on dive bombers, which needed to dive very steeply, but without exceeding their red line speed, in order to drop their bombs accurately. The airbrakes or spoilers fitted to gliders often function both as landing aids, to adjust the approach angle, and to keep the aircraft's speed below its maximum permissible indicated air speed in a vertical dive. Most modern combat aircraft are equipped with air brakes, which perform the same function as dive brakes. Applications * Aichi D3A * Dornier Do 217 (attachable dorsal/ventral "petal" design at extreme rear of fuselage) * Douglas SBD Dauntless * Junkers Ju 87 * Nelson Hummingbird PG-185B ...

Schweizer 1-34
The Schweizer SGS 1-34 is a United States Standard Class, single-seat, high-wing glider built by Schweizer Aircraft of Elmira, New York.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 32. Soaring Society of America, November 1983. USPS 499-920 The 1-34 was designed over a number of years in the mid-1960s and first flew in 1969. By the time the 1-34 was introduced it was no longer competitive in the Standard Class, but has proven very successful as a club aircraft, being a great "step-up" sailplane for post-solo students and accomplished pilots.Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', page 241. Smithsonian Institution Press, 1988. Design and development The 1-34 was designed over several years to spread out the development costs. At the time the design work on the aircraft was started the Standard Class was new and described a very simple aircraft with terminal velocity dive brakes, fixed landing gear and no w ...
