The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions.
Romney Marsh is a sparsely populated wetland area in the counties of Kent and East Sussex in the south-east of England. It covers about 100 square miles (260 km2). The Marsh has been in use for centuries, though its inhabitants commonly suffered from malaria until the 18th century. Due to its location, geography and isolation, it was important for smugglers between the 17th and 19th centuries. The area has long been used for sheep pasture: Romney Marsh sheep are considered one of the most successful and important sheep breeds. Featuring numerous waterways, and with some areas lying below sea level, the Marsh has over time sustained a gradual level of reclamation, both through natural causes and by human intervention.
Dungeness is a headland on the coast of Kent, England, formed largely of a shingle beach in the form of a cuspate foreland. It shelters a large area of low-lying land, Romney Marsh. Dungeness spans Dungeness Nuclear Power Station, the hamlet of Dungeness, and an ecological site at the same location. It lies within the civil parish of Lydd.
The Thornborough Henges are an ancient monument complex that includes the three aligned henges that give the site its name. They are located on a raised plateau above the River Ure near the village of Thornborough in North Yorkshire, England. The site includes many large ancient structures including a cursus, henges, burial grounds and settlements.
Royal Air Force Manston or more simply RAF Manston is a former Royal Air Force station located in the north-east of Kent, at grid reference TR334663 on the Isle of Thanet from 1916 until 1996. The site was split between a commercial airport Kent International Airport (KIA), since closed, and a continuing military use by the Defence Fire Training and Development Centre (DFTDC), following on from a long-standing training facility for RAF firefighters at the RAF Manston base.
ROTOR was an elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet bombers. To get it operational as quickly as possible, it was initially made up primarily of WWII-era systems, notably the original Chain Home radars for the early warning role, and the AMES Type 7 for plotting and interception control. Data from these stations was sent to a network of control stations, mostly built underground, using an extensive telephone and telex network.
An acoustic mirror is a passive device used to reflect and focus (concentrate) sound waves. Parabolic acoustic mirrors are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor sporting events. Pairs of large parabolic acoustic mirrors which function as "whisper galleries" are displayed in science museums to demonstrate sound focusing.
A sonobuoy is a small expendable sonar buoy dropped from aircraft or ships for anti-submarine warfare or underwater acoustic research. Sonobuoys are typically around 13 cm (5 in) in diameter and 91 cm (3 ft) long. When floating on the water, sonobuoys have both a radio transmitter above the surface and hydrophone sensors underwater.
RAE Bedford was a research site of the Royal Aircraft Establishment between 1946 and 1994. It was located near the village of Thurleigh, north of the town of Bedford in England and was the site of aircraft experimental development work.
Lise Autogena is a Danish artist living in the United Kingdom. At the age of 17, she left home to live in Denmark's experimental community Christiania, an experience which she has said was very important in her development.
Acoustic location is a method of determining the position of an object or sound source by using sound waves. Location can take place in gases, liquids, and in solids.
Romney Sands Railway Station is a station on the Romney, Hythe and Dymchurch Railway in Kent, England. It is located on the bleakest part of the Romney Marsh, a shingle peninsula.
Royal Air Force Westonzoyland, or more simply RAF Westonzoyland, is one of the United Kingdom's oldest airfields, being established in the early 1920s. The airfield is located approximately 4 miles (6.4 km) east-southeast of Bridgwater, Somerset; about 125 miles (201 km) west-southwest of London.
Royal Air Force Ventnor or more simply RAF Ventnor is a former Royal Air Force radar station located 0.7 miles (1.1 km) north east of Ventnor on the Isle of Wight, England. It was initially constructed in 1937 as part of a World War II coastal defence programme codenamed Chain Home. The site played an important role during the Second World War, providing early warnings of incoming bomber attacks carried out by the Luftwaffe.
Major William Sansome Tucker was an English pioneer in acoustical research and inventor of the acoustic mirror
Royal Air Force Holmpton or more simply RAF Holmpton is a former Royal Air Force Cold War era nuclear bunker that was built in the 1950s as an early warning radar station as part of the ROTOR Radar Defence Programme. Located just south of the village of Holmpton, in the East Riding of Yorkshire, England, RAF Holmpton remained a part of the Defence Estate right up to 8 December 2014 when it was sold into private ownership after 62 years of military service.
Denge Marsh, also spelled Dengemarsh and occasionally called the Denge, is a part of Romney Marsh in Kent. Its north-west boundary is the town of Lydd; to the south-east is Denge Beach and Dungeness.
RSPB Dungeness is a nature reserve owned and managed by the Royal Society for the Protection of Birds (RSPB)
Bent Rigg Radar Station,, was a radar site located at Bent Rigg, 0.6 miles (1 km) south of Ravenscar, North Yorkshire, England. Several radar stations had been located in the Ravenscar area from 1938, but a more permanent site was built at Bent Rigg in 1941, which was crewed by technicians and other staff from the Royal Air Force. Bent Rigg, and the wider location around Ravenscar, was deemed "attractive" for the siting of long-range finding equipment. It was originally part of the Coastal Defence/Chain Home Low (CD/CHL) system, designed to detect shipping. Later, it was upgraded with more powerful equipment as part of the Chain Home Extra Low (CHEL). The last recorded use of the station was in September 1944, and it is believed that the site closed soon afterwards.
Il-Widna is a large acoustic mirror located in Magħtab, Malta.' The colloquial name of the acoustic mirror refers to Ear in Maltese. The mirror is 200 feet (61 m) long, approximately the same design as the sound Mirror in RAF Denge. The mirror was used during the Axis bombardment of Malta during the Second World war to detect incoming Luftwaffe (1941-1942) and Regia Aeronautica (1940-1941) bombers seeking to airstrike Malta. Il-Widna faces towards the island of Sicily, in Italy at a bearing of around 20 degrees. The mirror is also the only acoustic not built in the UK. Il-Widna was built between the autumn of 1934 and the summer of 1935. The required electrical equipment was installed in the first weeks of September 1935. The total cost of the development of the mirror on Malta was put at £4500. Tests making use of a flying boat found that the range of the mirror was around 25 miles (40 km). It was estimated that the mirror would provide a six minute warning of an enemy aircraft approaching Malta at 250 miles per hour (220 kn).
