Gehrlein Precursor
The Gehrlein Precursor is an American, high-wing, single seat glider designed by Larry Gehrlein in 1965 and assembled from Schweizer Aircraft parts.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 28 and 43. Soaring Society of America November 1983. USPS 499-920 Design and development There was just one Schweizer 1-23C built and it was owned and modified by Gehrlein. The aircraft was crashed and rebuilt with new 1-23D wings. The 1-23C's damaged wings were rebuilt and formed the basis for the Precursor. The fuselage for the Precursor started life as a 1963 model Schweizer 1-26A. The two components were reworked by Gehrlein and his two sons, Rod and Jay, in 1965. They took the 1-26A fuselage and mounted the wings from the Schweizer 1-23C, modifying the fuselage, which had mounted the original 1-26 wings in the mid position to accept the 1-23C wings in the high position. The resulting aircraft is registered with the Federal Aviation Administration in the ''Expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schweizer 1-23C
The Schweizer SGS 1-23 is a United States Open and Standard Class, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. The original "standard" 1-23 was introduced in 1948. The aircraft quickly became the most numerous competition and performance sailplane in the USA. A total of 93 of all sub-models were built by the time production was completed in 1967. Design and development Schweizer Aircraft started construction of the 1-23 prototype in May 1948. The aircraft was completed and first flew on 5 July 1948, only nine weeks after construction had begun. The prototype had been ordered by Bill Frutchy of Elmira, New York and the aircraft was available for him to fly it in the second half of the US Nationals. The first production 1-23 was ordered by E.J Reeves. The success of this aircraft led to more orders and series production was commenced. The 1-23 was initially sold on a "factory direct" basis, which allowed them to be sold at a lower price than thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Gehrlein GP-1
The Gehrlein GP-1 is an American mid-wing, single seat FAI Standard Class glider that was designed by Jay and Rod Gehrlein and first flown in July 1968.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 43. Soaring Society of America November 1983. USPS 499-920 Design and development When their father, glider pilot Larry Gehrlein was on an extended vacation, his two sons, Rod and Jay decided to design and build a new glider as a surprise for his return. The resulting GP-1 was designed and built in under a year, between the summer of 1968 and the summer of 1969. Unlike Larry Gehrlein's earlier Gehrlein Precursor, the GP-1 is an original design and uses no Schweizer Aircraft parts in its construction. The GP-1 is an all-metal aircraft, with a wingspan. The wing is of a constant chord and employs a Wortmann FX-61-184 airfoil. Glide path control is via a set of scissor-type spoilers and air brakes. The design was intended to be simple to construct. Kits were a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NACA
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA is an initialism, i.e., pronounced as individual letters, rather than as a whole word (as was NASA during the early years after being established). Among other advancements, NACA research and development produced the NACA duct, a type of air intake used in modern automotive applications, the NACA cowling, and several series of NACA airfoils, which are still used in aircraft manufacturing. During World War II, NACA was described as "The Force Behind Our Air Supremacy" due to its key role in producing working superchargers for high altitude bombers, and for producing the laminar wing profiles for the North American P-51 Mustang.

Mid-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Schweizer 1-26A
The Schweizer SGS 1-26 is a United States One-Design, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York.Schweizer Aircraft Corp: The 1-26 Sailplane Flight - Erection - Maintenance Manual, Models A thru E'' page 1. Schweizer Aircraft Corp, undated. The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. The 1-26 was replaced in production by the Schweizer SGS 1-36 Sprite. The 1-26 is the most numerous sailplane found in the US. In October 1963 a special issue of ''Soaring'' magazine was dedicated to the 1-26. Harner Selvidge wrote: "Much of the glamour of soaring lies in the realm of high performance, high aspect ratio open class sailplanes, but the backbone of the soaring movement in this country, and any other, lies in the local club operations. These are the weekend fliers who have fun around the airport, make some cross-country flights and enter local contests. For this sort of flying, t ...

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] |
