Miss Shilling's orifice Miss Shilling's orifice was a very simple technical device made to counter engine cut-out in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain. While it was officially called the R.A.E. restrictor, it was normally referred to under various names, such as Miss Tilly's diaphragm or the Tilly orifice in reference to its inventor, Beatrice "Tilly" Shilling.

Beatrice Shilling Beatrice (Tilly) Shilling OBE PhD MSc CEng (8 March 1909 – 18 November 1990) was a British aeronautical engineer and motor racer. During the Second World War, she invented "Miss Shilling's orifice", a small metal disc similar to a metal washer that restricted fuel flow to the carburetor helping prevent engine stall in the Rolls-Royce Merlin engines of the Hawker Hurricane and Supermarine Spitfire fighters, which could lose power or even completely cut out during certain manoeuvres; a significant disadvantage in active service.

Davis wing The Davis wing is an aircraft wing design that was used for some time on a variety of World War II aircraft, most notably a number of designs from Consolidated Aircraft, the most notable being the Consolidated B-24 Liberator. Thicker and with lower drag than most contemporary designs, it allowed high speeds and lift even at high angles of attack. Its use ended almost immediately following World War Two.

Short Type 184 The Short Admiralty Type 184, often called the Short 225 after the power rating of the engine first fitted, was a British two-seat reconnaissance, bombing and torpedo carrying folding-wing seaplane designed by Horace Short of Short Brothers. It was first flown in 1915 and remained in service until after the armistice in 1918. A Short 184 was the first aircraft to sink a ship using a torpedo, and another was the only British aircraft to take part in the Battle of Jutland.

Nose gunner A nose gunner or front gunner is a crewman on a military aircraft who operates a machine gun or autocannon turret in the front, or "nose", of the airplane. This position could be manned by someone who was a dedicated gunner, however, it was more common for him to have a dual role, the gunnery being a secondary position (i.e. his primary task is navigator, bombardier, most commonly). This is different from fixed guns mounted in the nose and fired by the pilot or co-pilot, since those do not require a nose gunner. Manned nose guns were most common during WWI and World War II, employed by both Allied and Axis forces. Early in WWI, nose-gunners enjoyed a period of popularity on pusher-engined fighters; a gunner would be stationed in the nose, covering the arc ahead of the aircraft. Once the synchronizer was invented, allowing a fixed machine gun to fire through the propellor, the pusher-engined fighter fell into disuse, although nose guns were still commonly seen on multi-engine bomber aircraft.

Messerschmitt Me 262 The Messerschmitt Me 262, nicknamed Schwalbe (German: "Swallow") in fighter versions, or Sturmvogel (German: "Storm Bird") in fighter-bomber versions, was the world's first operational jet-powered fighter aircraft. Design work started before World War II began, but problems with engines, metallurgy and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944. The Me 262 was faster and more heavily armed than any Allied fighter, including the British jet-powered Gloster Meteor. One of the most advanced aviation designs in operational use during World War II, the Me 262's roles included light bomber, reconnaissance and experimental night fighter versions.

Hawker Tempest The Hawker Tempest is a British fighter aircraft primarily used by the Royal Air Force (RAF) in the Second World War. The Tempest, originally known as the "Typhoon II", was an improved derivative of the Hawker Typhoon, intended to address the Typhoon's unexpected fall-off of performance at high altitude by replacing its wing with a thinner laminar flow design. Having diverged considerably from the Typhoon, it was chosen to rename the aircraft "Tempest". The Tempest emerged as one of the most powerful fighters of World War II and was the fastest single-engine propeller-driven aircraft of the war at low altitude. The propeller-driven Dornier 335 was even faster, but it had two engines.

High-lift device In aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing. The device may be a fixed component, or a movable mechanism which is deployed when required. Common movable high-lift devices include wing flaps and slats. Fixed devices include leading edge root extensions and boundary layer control systems, which are less commonly used.

Littlejohn adaptor The Littlejohn adaptor was a device that could be added to the British QF 2 pounder (40 mm) anti-tank gun. It was used to extend the service life of the 2-pounder during the Second World War by converting it to squeeze bore operation. "Littlejohn" came from the literal anglicization of the name of František Janeček, the Czech designer and factory owner who had been working on the squeeze-bore principle in the 1930s and his son František Karel Janeček, who had brought his know-how to Britain after fleeing from German-occupied Czechoslovakia.

V-2 sounding rocket German V-2 rockets captured by the United States Army at the end of World War II were used as sounding rockets to carry scientific instruments into the earth's upper atmosphere at White Sands Missile Range (WSMR) for a program of atmospheric and solar investigation through the late 1940s. Rocket trajectory was intended to carry the rocket about 100 mi high and 30 mi horizontally from WSMR Launch Complex 33. Impact velocity of returning rockets was reduced by inducing structural failure of the rocket airframe upon atmospheric re-entry. More durable recordings and instruments might be recovered from the rockets after ground impact, but telemetry was developed to transmit and record instrument readings during flight.

Reflex receiver A reflex radio receiver, occasionally called a reflectional receiver, is a radio receiver design in which the same amplifier is used to amplify the high-frequency radio signal (RF) and low-frequency audio (sound) signal (AF). It was first invented in 1914 by German scientists Wilhelm Schloemilch and Otto von Bronk, and rediscovered and extended to multiple tubes in 1917 by Marius Latour and William H. Priess. The radio signal from the antenna and tuned circuit passes through an amplifier, is demodulated in a detector which extracts the audio signal from the radio carrier, and the resulting audio signal passes "again" through the same amplifier for audio amplification before being applied to the earphone or loudspeaker. The reason for using the amplifier for "double duty" was to reduce the number of active devices, vacuum tubes or transistors, required in the circuit, to reduce the cost. The economical reflex circuit was used in inexpensive vacuum tube radios in the 1920s, and was revived again in simple portable tube radios in the 1930s.

H2S (radar) H2S was the first airborne, ground scanning radar system. It was developed for the Royal Air Force's Bomber Command during World War II to identify targets on the ground for night and all-weather bombing, allowing attacks outside the range of the various radio navigation aids like Gee or Oboe, which were limited to about 500 km . It was also widely used as a general navigation system, allowing landmarks to be identified at long range.

Zeppelin A Zeppelin was a type of rigid airship named after the German Count Ferdinand von Zeppelin (] ) who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word "zeppelin" came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I the German military made extensive use of Zeppelins as bombers and scouts, killing over 500 people in bombing raids in Britain.

Barrage balloon A barrage balloon, sometimes called a blimp, is a large balloon tethered with metal cables, used to defend against aircraft attack by damaging the aircraft on collision with the cables, or at least making the attacker's approach more difficult. Commonly the designs were kite balloons, having a shape and cable bridling which stabilise the balloon in windy conditions, allowing more effective operation in higher winds than a spherical balloon. Some examples carried small explosive charges that would be pulled up against the aircraft to ensure its destruction. Barrage balloons are not practical against very high-flying aircraft, due to the weight of a very long cable.

Fog Investigation and Dispersal Operation Fog Investigation and Dispersal Operation (FIDO) (which was sometimes referred to as "Fog Intense Dispersal Operation" or "Fog, Intense Dispersal Of") was a system used for dispersing fog and pea soup fog (dense smog) from an airfield so that aircraft could land safely. The device was developed by Arthur Hartley for British RAF bomber stations, allowing the landing of aircraft returning from raids over Germany in poor visibility by burning fuel in rows on either side of the runway.
