Elliots of Newbury (EoN)

Elliots of Newbury grew out of an old-established joinery works that had existed oa a part of the Albert Works, Newbury, Berkshire site since the mid-nineteenth century. After the 1914-18 wat a change to furniture manufacture was made. During the Second World War Elliots became involved with glider manufacture, one of a number of furniture manufacturers that co-operated in the building of the large transport gliders. Elliots built about one third of the total Horsa production including the development of the hinged nose for the Mark 2 version, and it was also responsible for powered version of the Hamilcar glider. However, Elliots prime interest was the making of furniture. At the end of the war, when the contracts for transport gliders were coming to an end, the firm was hoping to resume furniture manufacture but, for technical reasons, was not “designated” by the Board of Trade for the manufacture of “Utility” furniture.

Early in 1945 the company was approached by Chilton Aircraft Ltd to make one pair of wings for the Chilton Olympia. Elliots had, by then, already planned to manufacture the Newbury Eon four-seat light aircraft but they agreed to make one pair of wings only for the Chilton prototype. Elliots refused to sell Chilton’s the wing jigs and maintained legal rights and ownership of their own manufactured jigs. Chilton’s later gave up all aircraft work and an agreement was subsequently reached whereby Elliots purchased from Chilton the production rights, fuselage jigs, and work in hand on all Olympia sailplanes.

Quantity production of the Eon Olympia commenced in 1946, and was followed in 1948 by the production of two further ex-German designs, the Grunau Baby sailplane and the SG.38 primary glider. Elliots, and their design consultants Aviation & Engineering Products Ltd, introduced improvements in each of the designs before commencing production.

Meanwhile, the Newbury Eon aircraft had its first flight in August 1947, and, in conjunction with their consultants, they produced a Design Study and tendered to the Air Ministry specification T.16/48 for a two-seat training aircraft in competition with Percival, Handley Page, and Auster. No further aircraft were produced by Elliots but aircraft parts were made, under sub-contract.

In 1954 a new version of the Olympia was produced as the original design was nearly fifteen years old. The Olympia 4, later known as the 401, was the first in a series of gradual stages of improvement and led to the 402 in 1956, the 403 in 1957, and finally, in 1958, to the Open Class 419 with its companion the 415 for the fifteen-metre Standard Class. Limited production of these latter types was then initiated. A completely new Standard Class sailplane was introduced in 1961 known as the Type 460. This was put into production and became very popular in Britain, resulting in a special version, the Type 465, being developed for the 1965 World Championships.

In the summer of 1965 the Managing Director of Elliots, M H.C.G. Buckingham died. He had been a keen supporter of the gliding movement for many years. After his death Elliots carried out a review of the firm’s activities and decided that it was time to end glider production due to its increasing unprofitability. A joint advertisement in the April 1966 “Sailplane & Gliding” announced that Slingsby Sailplanes Ltd had taken over the production of Eon Sailplanes. However, no Elliots designed gliders were ever built at Kirkbymoorside although spares were supplied and repairs undertaken.

Ellehammer, J.C.H.

Jacob Christian Ellehammer was first apprenticed as a watchmaker, he then qualified as an electrical engineer; he made one of the earliest motor-cycles built in Denmark, and also designed his own internal combustion engines. His 3-cylinder piston engine of 1903 was perhaps the world’s first radial engine, and his experiments in aviation, started two years later, embraced monoplanes, biplanes, triplanes, flying boats and helicopters.

After the 1912 helicopter, Ellehammer then put aside his helicopter experiments until about 1930, when he began to evolve some new projects. One of these was, in effect, a parasol monoplane in whose wings was a huge circular cut-out with two contra-rotating rotors turning inside it. Even more novel was a proposal in the mid-1930s for a helicopter driven by compressed air. As with the previous project, only a working model was built, powered by a vacuum cleaner motor. In the full-sized aircraft Ellehammer proposed to have a radial engine driving a powerful air compressor. A substantial pylon over the fuselage was topped by a metal disc, made to rotate by the reaction from expelling compressed air through slots in its underside. The centrifugal force of the rotating disc was sufficient to unsheath four spring-loaded rotor blades; when take-off had been accomplished, these were retracted back into the disc and the compressed air stream diverted to an efflux at the rear of the aircraft to give it forward movement.

Elicotteri Meridionale

Italy
Formed by Agusta in 1963 as part of industrialization program in south Italy, operating Frosinone factory, which opened in October 1967, overhauling helicopters for Italian services. In April 1968 concluded agreement for license production of Boeing-Vertol CH-47C Chinook for Italian Army and for Iran. Also developed Agusta-designed EMA124 three-seat helicopter based on Agusta-Bell 47. Now known simply as Sesto Calende (VA) facility of Agusta.

Elias, G. & Brothers Inc

USA
Formed in 1881 but made aircraft only after First World War, at Buffalo, NY. By 1929 had made nine experimental types for U.S. air services and Post Office, as well as armament types for the Air Corps. In 1922 made first of seven EM/EO “Marine Expeditionary” two-seat biplanes (wheels or floats). XNBS-3, tested August 1924, was large twin-engined bomber with steel-tube fuselage and wooden wings. Elias-Stupar was twin-engined cantilever civil biplane. EC-1 of 1927-1928 was “convertible” light parasol monoplane; the cockpit could be open or closed.

ELA Aviacion

ELA Aviacion, Spain, has been dedicated to aircraft manufacturing and maintenance since 1996. ELA Aviacion is the only Spanish company to make autogyros. Both models are made according to their own designs and awarded certificates by the Spanish Civil Aviation Board.
Developing this machine represented six years of research and experimentation in the mechanical and aerodynamic design required for the project.

Eklund Engineering, Inc. is an aero-mechanical consulting firm which holds the rights to the Thorp T-18 and John Thorp’s engineering legacy. The Thorp T-18 was designed by John Willard Thorp as the first good all metal homebuilt design. The two place side by side design was first envisioned as an open cockpit, uncowled, simple to build sport plane to use the converted Lycoming O-290G ground power engine. It soon grew into a high performance design which incorporated pressure cowl, canopy and slotted flaps. The T-18 can use any of the Lycoming O-290, 320, 340, 360 engines.
