De Havilland Tiger Moth
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland, de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer (aircraft), trainer aircraft. In addition to the type's principal use for ''ab initio'' training, the World War II, Second World War had RAF Tiger Moths operating in other capacities, including Maritime patrol aircraft, maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers. The Tiger Moth remained in service with the RAF until it was replaced by the de Havilland Canada DHC-1 Chipmunk, de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is s ...

Radio-controlled Aircraft
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver (radio), receiver within the craft that sends signals to servomechanisms (servos) which move the Flight control surfaces, control surfaces based on the position of joysticks on the transmitter. The control surfaces, in turn, directly affect the orientation of the plane. Flying RC aircraft as a hobby grew substantially from the 2000s with improvements in the cost, weight, performance, and capabilities of motors, battery (electricity), batteries and electronics. Scientific, government, and military organizations are also using RC aircraft for experiments, gathering weather readings, aerodynamics, aerodynamic modeling, and testing. A wide variety of models, parts, and styles is available for the DIY market. Nowadays, distinct from recreational c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loitering Munition
A loitering munition, also known as a suicide drone, kamikaze drone, or exploding drone, is a weapon with a warhead that is typically designed to Loiter (aeronautics), loiter until a target is designated, then crash into it.Watch This Drone Turn Into A Missile ''Popular Science'', August 2015 They enable attacks against hidden targets that emerge for short periods without placing high-value weapons platform, platforms near the target area. Unlike many other types of munitions, their attacks can be changed mid-mission or aborted. Loitering munitions are typically aerial platforms, but include some autonomous undersea vehicles with similar characteristics. Loitering weapons emerged in the 1980s for the Suppression of Enemy Air Defenses role, and were deployed for SEAD by some military forces ...

Missile
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic Force
In fluid mechanics, an aerodynamic force is a force exerted on a body by the air (or other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. Force There are two causes of aerodynamic force: *the normal force due to the pressure on the surface of the body *the shear force due to the viscosity of the gas, also known as skin friction. Pressure acts normal to the surface, and shear force acts parallel to the surface. Both forces act locally. The net aerodynamic force on the body is equal to the pressure and shear forces integrated over the body's total exposed area. When an airfoil moves relative to the air, it generates an aerodynamic force determined by the velocity of relative motion, and the angle of attack. This aerodynamic force is commonly resolved into two components, both acting through the center of pressure: *'' drag'' is the force component parallel to the direction of relative motion, *'' lift'' is the force com ...

Queen Bee
A queen bee is typically an adult, mated female ( gyne) that lives in a colony or hive of honey bees. With fully developed reproductive organs, the queen is usually the mother of most, if not all, of the bees in the beehive. Queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature. There is normally only one adult, mated queen in a hive, in which case the bees will usually follow and fiercely protect her. The term "queen bee" can be more generally applied to any dominant reproductive female in a colony of a eusocial bee species other than honey bees. However, as in the Brazilian stingless bee ('' Schwarziana quadripunctata''), a single nest may have multiple queens or even dwarf queens, ready to replace a dominant queen in case of a sudden death. Development During the warm parts of the year, female "worker" bees leave the hive every day to collect nectar and pollen. While male bees serve no architectural or pollinating ...

Drone (bee)
A drone is a male bee. Unlike the female worker bee, a drone has no stinger. He does not gather nectar or pollen and cannot feed without assistance from worker bees. His only role is to mate with a maiden queen in nuptial flight. Genetics Drones carry only one type of allele at each chromosomal position, because they are haploid (containing only one set of chromosomes from the mother). During the development of eggs within a queen, a diploid cell with 32 chromosomes divides to generate haploid cells called gametes with 16 chromosomes. The result is a haploid egg, with chromosomes having a new combination of alleles at the various loci. This process is called arrhenotokous parthenogenesis or simply arrhenotoky. Because the male bee technically has only a mother, and no father, their genealogical tree is unusual. The first generation has one member (the male). One generation back also has one member (the mother). Two generations back are two members (the mother and father of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
