Teddy bear parachuting, sometimes referred to as parafauna, is a game in which teddy bears equipped with parachutes are dropped from a height. It is increasing in popularity as a charity fundraiser, and competitions based on the descent time are also common.
A typical teddy bear parachute may be made from an old umbrella canopy or other lightweight material. A simple hemispherical pattern of multiple tapered gores may be sewn from ripstop nylon kite or sail fabric. [1] Many bears are dressed and fully equipped with parachute packs, helmets and goggles.
While jumps are commonly from high buildings such as church towers [3] [4] and castles, some are more ambitious, with at least one regular event including parachuting from a light aircraft. [5]
The first bears to do a jump from a light aircraft are still around, and go under the name of the "Ted Devils". A unique item that takes place at airshows (including those at fetes and private functions) devised and run by a well known UK display pilot and aircraft. [6] Additionally, these bears are fund raisers that support the local community, by letting the local community take part in the event before the day. [7]
Parachuting bears are also lifted by kite and released with a dropper mechanism. This method is cheap and highly portable. [8] Kites such as parafoils or large deltas are particularly suitable for this. [1] As many kite fliers also make their own kites, the parachutes are usually self-manufactured too. Most bears must be lifted aloft along with the kite. Some small bears may be transported along the line of an already flying kite by a messenger, a small carriage with sails. [9] When the messenger reaches the top of the kite line, the bear is released automatically. [1] This is a much simpler method for repeated drops or charity events.
The parachuting of teddy bears was used as a political statement when several hundred of the stuffed toys bearing protest slogans were dropped over the Belarus city of Minsk on 4 July 2012. [10]
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs do not need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from the kite, the hovering bird of prey.
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised, heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame.
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
A fixed-wing aircraft is a heavier-than-air flying machine, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft, and ornithopters. The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft, and airplanes that use wing morphing are all classified as fixed-wing aircraft.
The Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogallo Wing" and flexible wing. NASA considered Rogallo's flexible wing as an alternative recovery system for the Mercury and Gemini space capsules, and for possible use in other spacecraft landings, but the idea was dropped from Gemini in 1964 in favor of conventional parachutes.
A power kite or traction kite is a large kite designed to provide significant pull to the user.
For fixed-wing aircraft, autorotation is the tendency of an aircraft in or near a stall to roll spontaneously to the right or left, leading to a spin.
Kite types, kite mooring, and kite applications result in a variety of kite control systems. Contemporary manufacturers, kite athletes, kite pilots, scientists, and engineers are expanding the possibilities.
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the harvested and/or generated power back to earth, and interference with aviation.
Airborne wind energy (AWE) is the direct use or generation of wind energy by the use of aerodynamic or aerostatic lift devices. AWE technology is able to harvest high altitude winds, in contrast to wind turbines, which use a rotor mounted on a tower.
A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to an observer's basket.
British Parachute Schools also known as Langar DZ or Skydive Langar is a BPA affiliated parachuting centre and skydiving drop zone at Langar, Nottinghamshire in the area known as the Vale of Belvoir.
Richard Steiff was a German designer, known for creating one of the first teddy bears. In 1897, he joined Steiff, a stuffed toy company founded in his hometown Giengen by his aunt Margarete Steiff, and became integral to its growth as a global toy company.
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude with some being powerful enough to take off by self-launch.
Different types of flying kites have niche applications. In nature, some animals, such as spiders, also make use of kiting.
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind for generation of airflow over the lifting surfaces.
A rotor kite or gyrokite is an unpowered, rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly. Unlike a helicopter, gyrokites and rotor kites do not have an engine powering their rotors, but while an autogyro has an engine providing forward thrust that keeps the rotor turning, a rotor kite has no engine at all, and relies on either being carried aloft and dropped from another aircraft, or by being towed into the air behind a car or boat or by use of ambient winds for the kiting. As of 2009, no country in the world requires a license to pilot such a craft.
The A-1 lifeboat was a powered lifeboat that was made to be dropped by fixed-wing aircraft into water to aid in air-sea rescue operations. The sturdy airborne lifeboat was to be carried by a heavy bomber specially modified to handle the external load of the lifeboat. The A-1 lifeboat was intended to be dropped by parachute during Dumbo missions to land within reach of the survivors of an accident on the ocean, specifically airmen survivors of an emergency water landing.
Aerial advertising is a form of advertising that incorporates the use of flogos, manned aircraft, or drones to create, transport, or display, advertising media. The media can be static, such as a banner, logo, lighted sign or sponsorship branding. It can also be dynamic, such as animated lighted signage, skywriting, or audio.
Teddybear Airdrop Minsk 2012 was an aerial event that took place over Belarus on July 4, 2012. An airplane, chartered by the Swedish advertising agency Studio Total, illegally entered the Belarusian airspace on July 4 and parachuted several hundred teddy bears with notes carrying pro-democracy messages. After denying for three weeks that the incident ever took place and calling the footage of the airdrop released by Studio Total a hoax, the Belarus government finally acknowledged on July 26, 2012, that the teddy bear airdrop did happen.
