Radioplane Aircraft
The Radioplane Company was an American Aviation, aviation company that produced drone aircraft primarily for use as gunnery targets. During World War II, they produced over 9,400 of their Radioplane OQ-3 model, a propeller-powered monoplane, making it the most-used target aircraft in the US. In the post-World War II era they introduced their Radioplane BTT series, which was produced for years and eventually reached almost 60,000 examples. They also produced several radio control and self-guided missiles, the largest being the GAM-67 Crossbow, which did not enter service. The company was purchased by Northrop Corporation in 1952, and moved to one of Northrop's factories in 1962. One of the last projects carried out at the original Radioplane factory in Van Nuys, California, was the construction of the Advanced Gemini#Other proposals, Gemini Paraglider.

John Greenleaf Whittier
John Greenleaf Whittier (December 17, 1807 – September 7, 1892) was an American Quaker poet and advocate of the abolition of slavery in the United States. Frequently listed as one of the fireside poets, he was influenced by the Scottish poet Robert Burns. Whittier is remembered particularly for his anti-slavery writings, as well as his 1866 book '' Snow-Bound''. Early life and education Whittier was born to John and Abigail ( Hussey) Whittier at their rural homestead in Haverhill, Massachusetts, on December 17, 1807. His middle name is thought to mean ''feuillevert'', after his Huguenot forebears. He grew up on the farm in a household with his parents, a brother and two sisters, a maternal aunt and paternal uncle, and a constant flow of visitors and hired hands for the farm. As a boy, it was discovered that Whittier was color-blind when he was unable to see a difference between ripe and unripe strawberries. The farm was not very profitable, and there was only enough mone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioplane OQ-2
The Radioplane OQ-2 was the first mass-produced UAV or drone in the United States, manufactured by the Radioplane Company. A follow-on version, the OQ-3, became the most widely used target drone in US service, with over 9,400 being built during World War II. History The OQ-2 was originally a radio-controlled aircraft model designed by Walter Righter. The design, along with its engine design, was purchased by actor Reginald Denny, who had demonstrated another model to the US Army in 1940. Calling the new design the RP-2, he demonstrated several updated versions to the Army as the RP-2, RP-3 and RP-4 in 1939. In 1940, the Army placed an order for 53 RP-4s (some sources refer to the RP-4 as OQ-1. but that designation was never assigned). This small order led to a much bigger 1941 order for the similar RP-5, which became the US Army OQ-2, the ''OQ'' meaning a "subscale target". The US Navy also bought the drone, designating it TDD-1, for ''Target Drone, Denny, 1''. Thousands were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joystick
A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Also known as the control column, it is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It has various switches to control functions of the aircraft controlled by the Pilot and First Officer of the flight. Joysticks are often used to control video games, and usually have push-buttons whose state can be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and Zero-turn mower, zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. A ...

Muroc Dry Lake
Rogers Dry Lake is an Endorheic basin, endorheic desert salt pan (geology), salt pan in the Mojave Desert of Kern County, California. The lake derives its name from the Anglicization from the Spanish name, Rodriguez Dry Lake. It is the central part of Edwards Air Force Base as its hard surface provides a natural extension to the paved runways. It was formerly known as Muroc Dry Lake. Geology Rogers Dry Lake is located in the Antelope Valley, about drive north of Los Angeles. It covers an area of about at the low point of the valley, forming a rough figure eight. It is the bed of a lake that formed roughly 2.5 million years ago, in the Pleistocene. It is long and wide at its greatest dimensions. The bed of the lake is unusually hard, capable of withstanding as much as 250 psi without cracking. This is sufficient to allow even the heaviest aircraft to land safely. During the extremely brief rainy season, standing water may be on the lakebed, pooling near the location of the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packard
Packard (formerly the Packard Motor Car Company) was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana, in 1958. One of the "Three Ps" – alongside Peerless Motor Company and Pierce-Arrow – the company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are often found in museums and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Li ...

Aeronautical Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

Menasco Motors Company
The Menasco Manufacturing Company was an American aircraft engine and component manufacturer. History The company was organized by Albert S. Menasco in 1926 to convert World War I surplus Salmson Z-9 water-cooled nine-cylinder radials into air-cooled engines for private use. His association with John K. (Jack) Northrop and his flying wing project in the late 1920s convinced him of the need for a new configuration of aircraft engine: an inverted in-line air-cooled layout that would have the propeller shaft on top for better ground clearance and improved pilot vision. In 1929, Menasco designed his own engine, the 4-A, the first of what was to become Menasco's main product line, the inverted, in-line engine. Menasco designed and built a variety of four- and six-cylinder inverted air-cooled aircraft engines, some with supercharging. During WWII, Menasco manufactured aircraft landing gear for North American, Lockheed, Republic, General Dynamics, and others. After WWII, aircraft ...

Bridge Financing
A bridge loan is a type of short-term loan, typically taken out for a period of 2 weeks to 3 years pending the arrangement of larger or longer-term financing. It is usually called a bridging loan in the United Kingdom, also known as a "caveat loan," and also known in some applications as a swing loan. In South African usage, the term bridging finance is more common. A bridge loan is interim financing for an individual or business until permanent financing or the next stage of financing is obtained. Money from the new financing is generally used to "take out" (i.e. to pay back) the bridge loan, as well as other capitalization needs. Bridge loans are typically more expensive than conventional financing, to compensate for the additional risk. Bridge loans typically have a higher interest rate, points, costs that are amortized over a shorter period, and various other fees and "sweeteners" (such as equity participation by the lender in some loans). The lender also may require cross-col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parachute
A parachute is a device designed to slow an object's descent through an atmosphere by creating Drag (physics), drag or aerodynamic Lift (force), lift. It is primarily used to safely support people exiting aircraft at height, but also serves various purposes like slowing cargo, aiding in space capsule recovery, and stabilizing vehicles or objects. Modern parachutes are typically made from durable fabrics like nylon and come in various shapes, such as dome-shaped, rectangular, and inverted domes, depending on their specific function. The concept of the parachute dates back to ancient attempts at flight. In 852 AD, Armen Firman, in Córdoba, Spain, made the first recorded jump with a large cloak to slow his fall. Renaissance figures like Francesco di Giorgio Martini and Leonardo da Vinci later sketched designs resembling modern parachutes, but it wasn’t until the 18th century that the first successful jumps occurred. French Louis-Sébastien Lenormand made the first public jump i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
