Inverted Flight
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a par ...

Patty Wagstaff At KBJC
A patty or burger (in British English) is a flattened, usually round, serving of ground meat and/or legumes, grains, vegetables, or meat alternatives. Patties are found in multiple cuisines throughout the world. In British and American English, minced meat that is formed into a disc is called a burger, whether it is in a bread roll or not. The word “patty” is also used in American English but almost unknown in British English. The ingredients are compacted and shaped, usually cooked, and served in various ways. Some foods termed "patties" use ingredients inside a pastry crust that is then baked or fried. Some patties are breaded, then baked or fried. In London, since the late 1980s, the Jamaican patty, similar to the Cornish pastie, is a common food item. Etymology The term originated in the 17th century as an English alteration of the French word pâté. According to the OED, it is related to the word pasty, which is various ingredients encased in pastry. Termino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extra 300
The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, a German aerobatic pilot, and built by Extra Flugzeugbau. Design and development Design of the Extra 300 was based on the Extra 230, an early 1980s monoplane having a wing made of wood. The Extra 300 has a welded steel tube fuselage covered in aluminium and fabric. The midset wing has a carbon fiber composite spar and carbon composite skins.Lambert 1993, p. 100.

702 Naval Air Squadron
702 Naval Air Squadron (702 NAS) was a naval squadron of the Royal Navy's Fleet Air Arm. It was based at RNAS Yeovilton in Somerset and earlier at RNAS Portland in Dorset. As a training Squadron it trained all ground and air crew for the sister front-line maritime Lynx squadron, 815 NAS It merged with 700(W) NAS to form 825 NAS. 702 NAS disbanded on 1 August 2014. History Formation and WWII (1936 - 1945) 702 NAS was founded on 15 July 1936 to operate aircraft from the ships of the 2nd Battle Squadron. Operating Supermarine Walrus and Fairey Seal aircraft from its base at RAF Mount Batten initially, later these were replaced by the Fairey Swordfish float-plane. Granted Squadron status in 1939, and briefly disbanded in 1940, 702 Naval Air Squadron reformed as a Long Range Catapult squadron with Fairey Seafoxes for duty in Armed Merchant Cruisers for much of the Second World War.

Fleet Air Arm
The Fleet Air Arm (FAA) is one of the five fighting arms of the Royal Navy and is responsible for the delivery of naval air power both from land and at sea. The Fleet Air Arm operates the F-35 Lightning II for maritime strike, the AW159 Wildcat and AW101 Merlin for commando and anti-submarine warfare and the BAE Hawk as an aggressor. The Fleet Air Arm today is a predominantly rotary force, with helicopters undertaking roles once performed by biplanes such as the Fairey Swordfish. The Fleet Air Arm was formed in 1924 as an organisational unit of the Royal Air Force, which was then operating the aircraft embarked on RN ships—the Royal Naval Air Service having been merged with the Army's Royal Flying Corps in 1918 to form the Royal Air Force—and did not come under the direct control of the Admiralty until mid-1939. During the Second World War, the Fleet Air Arm operated aircraft on ships as well as land-based aircraft that defended the Royal Navy's shore establishments a ...

Aerosol
An aerosol is a suspension (chemistry), suspension of fine solid particles or liquid Drop (liquid), droplets in air or another gas. Aerosols can be natural or Human impact on the environment, anthropogenic. Examples of natural aerosols are fog or mist, dust, forest exudates, and geyser steam. Examples of anthropogenic aerosols include particulate air pollutants, mist from the discharge at Hydroelectric dam, hydroelectric dams, Irrigation, irrigation mist, Perfume, perfume from atomizers, smoke, steam from a kettle, Pesticide, sprayed pesticides, and medical treatments for respiratory illnesses. When a person inhales the contents of a vape pen or e-cigarette, they are inhaling an Human impact on the environment, anthropogenic aerosol. The liquid or solid particles in an aerosol have diameters typically less than micrometre, 1 μm (larger particles with a significant settling speed make the mixture a Suspension (chemistry), suspension, but the distinction is not clear-cut) ...

Smoke Screen
A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships. Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship). Whereas smoke screens were originally used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and they are also available for vehicles in a super-dense form used to block laser beams of enemy target designators or range finders. Technology Smoke grenades These are canister-type grenades used as a ground-to-ground or ground-to-air signalling device. The body consists of a steel sheet metal cylinder with a few emission holes on the top and/or bottom to allow smoke release when the smoke composition inside the grenade is ignited ...

Vaporization
Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon. Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs ''on the surface''. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure. For example, due to constantly decreasing pressures, vapor pumped out of a solution will eventually leave behind a cryogenic liquid. Boiling is also a phase transition from the liquid phase to gas phase, but boiling is the formation of vapor as bubbles of vapor ''below the surface'' of the liquid. Boiling occurs when the equilibrium vapor pressure of the substance is greater than or equa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colored Smoke
Colored smoke is a kind of smoke created by an aerosol of small particles of a suitable pigment or dye. Colored smoke can be used for smoke signals, often in a military context. It can be produced by smoke grenades, or by various other pyrotechnical devices. The mixture used for producing colored smoke is usually a cooler-burning formula based on potassium chlorate oxidizer, lactose or dextrin as a fuel, and one or more dyes, with about 40-50% content of the dye. About 2% sodium bicarbonate may be added as a coolant, to lower the burning temperature. Coloured smoke was first used in 1967 during an American burnout competition by a small contestant, as a means to wow the crowd. Smoke released from aircraft was originally based on a mixture of 10-15% dye, 60-65% trichloroethylene or tetrachloroethylene, and 25% diesel oil, injected into the exhaust gases of the aircraft engines. Most commonly, teams now use specifically prepared liquid dyes and only gas oil, light mineral oil or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Forces
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formation Flying
Formation flying is the flight of multiple objects in coordination. Introduction Formation flight in aviation originated in World War I when fighter aircraft were assigned to escort reconnaissance aircraft. It was found that pairs of aircraft were more combat effective than single aircraft, and therefore, military aircraft would always fly in formations of at least two. By World War II, pilots had discovered other strategic advantages to formation flight such as enhanced stability and optimal visibility. However, birds have been known to receive performance benefits from formation flight for over a century, through aerodynamic theory of Wieselsberger in 1914. Today, a multitude of studies have been performed on the performance benefits of aircraft flying in formation. Mechanism of drag reduction It is a common misunderstanding to relate the reduction of drag in organized flight to the reduction of drag in drafting. However, they are quite different mechanistically. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha 2000
The Alpha Aviation Alpha 2000 is a two-seat, all-metal training and general aviation aircraft, designed by Chris Heintz and built in Hamilton, New Zealand. It continues the successful French Apex Aircraft's Robin R2000 series acquired upon Apex's purchase of the Avions Robin company. History 1971–1994 The original Avions Robin HR200 was designed by Christophe Heintz, to supplement the earlier Avions Robin designs of Jean Délémontez who also designed the popular post war wooden Jodel. The HR 200 prototype first flew on 19 July 1971, and entered production in 1973. The R2000 Alpha name was applied to a new aircraft which shared the fuselage of the HR 200, but had all new wing and tail surfaces, to allow aerobatics. The prototype R2000 Alpha flew on 15 January 1976 and production followed in 1977 to 1983. The aircraft features side-by-side seating, an innovative control stick mechanism which reduces the risk of blockage and an unusually large payload for an aerobatic aircraf ...
