Parnall Prawn
The Parnall Prawn was an experimental flying boat built in the United Kingdom in 1930. Its single engine was fitted on a tilting mounting in the nose, so that the propeller could be kept clear of the water on takeoff and landing. Only one was built and it is not known whether it was ever flown. Design and development The Prawn was a small single-engined flying boat built by Parnall as a one-off to an Air Ministry contract. Single-engined flying boats are common, but the very unusual feature of the Prawn was that its engine was in the nose. There are obvious aerodynamic efficiencies, chiefly low drag, in putting the engine of a propeller driven landplane or floatplane in its nose, but flying boats sit low on the water and propeller clearance is a problem even when the aircraft is stationary. Once moving, spray also becomes a problem. The Prawn was built to see if these issues could be overcome. It combined two approaches, using a small propeller hinging the engine mounting ...

Empennage
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb ''empenner'' which means " to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally use ...

Parnall Aircraft
Parnall was a British aircraft manufacturer that evolved from a wood-working company before the First World War to a significant designer of military and civil aircraft into the 1940s. It was based in the west of England and was originally known as George Parnall & Co. Ltd. History In 1916, the Bristol based Parnall & Sons shopfitters started to manufacture aircraft at the Colliseum Works at Park Row in Bristol. During the First World War, the skilled staff were moved to sites around the city and in neighbouring South Gloucestershire producing planes to their own designs and, under contract, those of other companies. In 1919, the aircraft business was split from the parent company Parnall & Sons as George Parnall and Company. In the 1920s, aircraft manufacture was centralised at a factory in Yate close to an airfield used by the Royal Flying Corps. In the 1930s, gun turrets for bomber aircraft were produced. The site was a strategic target for Luftwaffe bombing and during 1941 ...

1930s British Experimental Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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 * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace. The Empire is auctioned off ...

Felixstowe
Felixstowe ( ) is a port town in Suffolk, England. The estimated population in 2017 was 24,521. The Port of Felixstowe is the largest container port in the United Kingdom. Felixstowe is approximately 116km (72 miles) northeast of London. History The town is named after Felix of Burgundy, a saint and the first bishop of the East Angles in the seventh century. The old Felixstowe hamlet was centred on a pub and church, having stood on the site since long before the Norman conquest of England. The early history of Felixstowe, including its Roman, Anglo-Saxon, Norman and medieval defences, is told under the name of Walton, because the name Felixstowe was given retrospectively, during the 13th century, to a place which had expanded to a form beyond the boundaries of Walton alone. In the Doomsday book, for instance, only Walton is shown, and not Felixstowe, which at the time held little more than a few houses scattered over the cliff tops. Walton was a settlement on the River Orwell ...

Marine Aircraft Experimental Establishment
The Marine Aircraft Experimental Establishment (MAEE) was a British military research and test organisation. It was originally formed as the Marine Aircraft Experimental Station in October 1918 at RAF Isle of Grain, a former Royal Naval Air Service seaplane base, to design, test and evaluate seaplanes, flying boats and other aircraft with a naval connection. It was renamed as the Marine and Armament Experimental Establishment on 16 March 1920 to recognise that weapons and other equipment were evaluated as well as complete aircraft. It was renamed again on 1 March 1924 as the Marine Aircraft Experimental Establishment. Relocations On 16 June 1924 the Establishment moved to the site of the former Seaplane Experimental Station seaplane base at Felixstowe. It carried out research and development work on water-based aircraft for service needs and also on their equipment and on air-sea rescue apparatus. The Establishment's work grew during its early years and by 1930 it was carrying o ...

Yate
Yate is a town and civil parish in South Gloucestershire, England. It lies just to the southwest of the Cotswolds, Cotswold Hills and is northeast of Bristol city centre and from the centre of Bath, Somerset, Bath, with regular rail services to Bristol and Gloucester. Developing from a small village into a town from the 1950s onwards, the 2011 UK census, census listed Yate's parish population as 21,789. The market town of Chipping Sodbury (population 5,045) is contiguous with Yate to the east. In addition, a large southern section of the built-up area spills over into the parish of Dodington, Gloucestershire, Dodington (population 8,206), and as a result, the total population of Yate's urban area is estimated at 35,000. Location Yate is located in South Gloucestershire in the South West of England. The town is northeast of Bristol city centre, which is about away by road. Apart from Chipping Sodbury to the east, Yate is surrounded by countryside and is situated to the south ...

Cabane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more impo ...

Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an airc ...

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 191 ...
