Parrish Aircraft Xperimental Inc
Parrish Aircraft Xperimental, Inc. was an American aircraft design firm based in Plantation, Florida and founded by Jimmy R. Parrish. The company specialized in the design of light aircraft, providing plans for amateur construction.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition'', page 354. BAI Communications, 15 July 1998. The company was founded to sell plans for the Parrish Dart design. The Dart design underwent a number of changes between its conception in 1983 as a delta-winged aircraft and its final 1995 canard configuration, greatly resembling the Rutan Long-EZ. The company was incorporated on 5 April 1996 and in April 2015 its corporate filing status was listed as "inactive". By 1998 the company reported that one aircraft had been completed and was flying. In April 2015 only one example, the prototype, was registered in the United States with the Federal Aviation Administration The Federal Aviation Administration (FAA) is the la ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantation, Florida
Plantation is a city in Broward County, Florida, United States. As of the 2020 U.S. census, the population was 91,750. It is a principal city of the Miami metropolitan area. The city's name comes from the previous part-owner of the land, the Everglades Plantation Company, and their unsuccessful attempts to establish a rice plantation in the area. History Land acquisition and drainage (1855–1930) Before the start of the twentieth century, the area that became Plantation was part of the Everglades wetlands, regularly covered by 2–3 feet of water. In 1855, Florida state passed the Internal Improvement Act and established the Internal Improvement Trust Fund, the trustees of which act as a government agency to oversee management, sale, and development of state land. In 1897, the Interior Department submitted 2.9 million acres to the Florida Land Office; however, the submission was revoked the following year, due to fears it would "impinge upon the rights and interests of the Sem ...

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Aircraft Design Process
The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Similar to, but more exacting than, the usual engineering design process, the technique is highly iterative, involving high level configuration tradeoffs, a mixture of analysis and testing and the detailed examination of the adequacy of every part of the structure. For some types of aircraft, the design process is regulated by civil airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs. Design constraints Purpose The design process starts with the aircraft's intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency where as fighter jets are designed to perform ...

Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parrish Dart
The Parrish Dart is an American canard-configuration homebuilt aircraft that was designed by Jimmy R. Parrish and produced by Parrish Aircraft Xperimental, Inc. of Plantation, Florida. It first flew in the Autumn of 1995. When it was available the aircraft was supplied in the form of plans for amateur construction.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition'', page 354. BAI Communications, 15 July 1998. Design and development The Parrish Dart started in 1983 as a delta-winged design, but was developed into a canard configuration resembling a Rutan Long-EZ. It features a cantilever mid-wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, fixed tricycle landing gear main gear with a retractable nosewheel and a single engine in pusher configuration. The aircraft is made from fiberglass, with the fuselage a fibreglass sandwich and the wings and canard built from fibreglass spars and solid-core fibreglass airfoil shapes cut with a ho ...

Delta-wing
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic flight. At the other end of the speed scale, the Rogallo flexible wing proved a practical design for the hang glider and other ultralight aircraft. The delta wing form has unique aerodynamic characteristics and structural advantages. Many design variations have evolved over the years, with and without additional stabilising surfaces. General characteristics Structure The long root chord of the delta wing and minimal structure outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent lifting capability. Because of this it is easy and relatively inexpensive to build – a substantial factor in the success of the MiG- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canard (aeronautics)
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better ...

Rutan Long-EZ
The Rutan Model 61 Long-EZ is a tandem 2-seater homebuilt aircraft designed by Burt Rutan's Rutan Aircraft Factory. The Long-EZ has a canard layout, a swept wing with wingtip rudders, and a pusher engine and propeller. The tricycle landing gear has fixed main wheels with streamlined spats and a retractable nosewheel. Its predecessor was the VariEze, plans for which were first available to homebuilders in 1976. The prototype Long-EZ, N79RA, first flew on June 12, 1979. Design The Long-EZ was a scaled-up redesign of the VariEze predecessor, allowing for the use of readily available Lycoming aircraft engines instead of the Volkswagen-derived engines or hard-to-find small Continentals for which the VariEze was designed. Changes from the VariEze included a larger main wing with modified Eppler 1230 airfoil and less sweep, larger strakes containing more fuel and baggage storage, and a slightly wider cabin. The canard uses the same GU25-5(11)8 airfoil as the VariEze. Plans were o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
