Jongblood Primary
The Jongblood Primary is an American single-seat, high-wing, strut-braced primary glider designed by Mike Jongblood of southern California and first flown in 1967. The aircraft is unusual in that primary gliders went out of fashion in the 1930s and few have been built since.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 44 Soaring Society of America November 1983. USPS 499-920 Design and development Jongblood designed and built this primary glider in 1966, with assistance from Hugh Knoop. The design was original and includes an original airfoil design as well, designated as a ''Jongblood II'' section. The aircraft is built from wood and covered in doped aircraft fabric covering. The glider has a detachable pod to cover the pilot or can be flown open cockpit. It has a constant chord wing with a chord and a span. The wing features dual parallel struts and jury struts, but has no spoilers or other glidepath control devices. The tailplane is also strut-braced. ...

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] |
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 ...

1960s United States Sailplanes
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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.

Slingsby Grasshopper
The Slingsby T.38 Grasshopper is a British primary training glider built by Slingsby Sailplanes for the Royal Air Force.Hardy 1982, p. 115. Development The design is based on the pre-World War II German SG 38 Schulgleiter, modified to use the wing design of the Slingsby T.7 Kirby Cadet glider. The design was cheap to manufacture and was designed to be stored dismantled. The type was used by Air Training Corps Squadrons between 1952 and the late 1980s. The RAF designated the glider the Grasshopper TX.1, and the first order was for 65 aircraft, which were delivered in 1952 and 1953. It was later followed by two further orders for an additional 50 aircraft; the final delivery was made in 1963. Launch is achieved through the use of a V-shaped bungee or elastic rope pulled by a team of helpers. The glider can also be mounted on a pivoting tripod pointed into wind for the demonstration of controls. The Grasshopper is virtually identical to the EoN Eton. Operators ; *Royal ...

Schweizer SGP 1-1
The Schweizer SGP 1-1 is an American, amateur-built, single-seat, high-wing primary glider that was designed by Ernest Schweizer and constructed by the Mercury Glider Club between 1929 and 1930.Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', pages 14-22. Smithsonian Institution Press, 1988. The 1-1 became the first in a line of 38 glider designs that the Schweizers created and the first of over 5700 aircraft built by them. A replica of the original 1-1 was constructed by a group of volunteers led by Ernst Schweizer in 1989 to celebrate 50 years of Schweizer sailplane construction. The SGP 1-1 has also been referred to as the SGU 1-1. Design and development In 1928 J.C. Penney III, son of founder of the J. C. Penney department store chain, provided financial backing for a glider pilot training school run by the American Motorless Aviation Corporation. In order to gain publicity AMAC sponsored some soaring flights at Corn Hill, Truro, Massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
