Pacific Aerospace 750XL
The PAC P-750 XSTOL, (formerly known as the PAC 750XL) is a utility aircraft of conventional all-metal low-wing monoplane design, with fixed tricycle undercarriage. Combining the engine and wings of the PAC Cresco with a new large fuselage and modified tail, all versions to date have been powered by a 750 hp (560 kW) Pratt & Whitney Canada PT6 turboprop. It is designed and manufactured in Hamilton, New Zealand by Pacific Aerospace Limited. Development The design made its maiden flight in 2001. As with the Cresco, horizontal tail surfaces presented difficulties, and these were redesigned before the type entered production. The PAC 750 received full US FAA certification in 2004. In 2008 the manufacturer stated production was increasing from 12 to 24 per year. In 2008 there was some New Zealand media criticism of government assistance for the manufacturer following cancellation of a large order. By February 2016, 100 aircraft had been produced, over 120 by Jan 2019. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Papua New Guinea Defence Force
The Papua New Guinea Defence Force (PNGDF) is the military organisation responsible for the defence of Papua New Guinea. It originated from the Australian Army land forces of the territory of Papua New Guinea before independence, coming into being in January 1973 and having its antecedents in the Pacific Islands Regiment. The PNGDF is a small force, numbering around 2,500 personnel, and consists of a Land Element, an Air Element and a Maritime Element. It is a joint force tasked with defending Papua New Guinea and its territories against external attack, as well as having secondary functions including national-building and internal security tasks. Defence accounts for less than 2% of GDP, while also receiving significant assistance and training support from Australia, New Zealand, the United States, and other nations. The Defence White Paper 2013 has ambitious plans to increase the force to 5,000 personnel and double defence spending to 3% by 2017 and by 2030 have 10,000 personne ...

Geophysical Survey
Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure. Hence, detection and analysis of the electric and Magnetic fields is very crucial. As the Electromagnetic and gravitational waves are multi-dimensional signals, all the 1-D transformation techniques can be extended for the analysis of these signals as well. Hence this article also discusses multi-dimensional signal processing techniques. Geophysical surveys may use a great variety of sensing instruments, and data may be collected from above or below the Earth's surface or from aerial, orbital, or marine platforms. Geophysical surveys have many applications in geology, archaeology, mineral and energy exploration, oceanography, and engineeri ...

Aerial Photography
Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures, it is also known as aerial videography. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloons, blimps and dirigibles, rockets, pigeons, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remotely operated or triggered automatically. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Elevated photography can also produce bird's-eye images closely resembling aerial photography (despite not actually being aerial shots) when ...

Aerial Application
Aerial application, or what is informally referred to as crop dusting, involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as ''aerial topdressing ''in some countries. Many countries have severely limited aerial application of pesticides and other products because of environmental and public health hazards like spray drift; most notably, the European Union banned it outright with a few highly restricted exceptions in 2009, effectively ending the practice in all member states. Agricultural aircraft are highly specialized, purpose-built aircraft. Today's agricultural aircraft are often powered by turbine engines of up to and can carry as much as of crop protection product. Helicopters are sometimes used, and some aircraft serve double duty as water bombers in areas prone to wildfires. These aircraft are referred to as SEAT ...

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachuting
Parachuting, including also skydiving, is a method of transiting from a high point in the atmosphere to the surface of Earth with the aid of gravity, involving the control of speed during the descent using a parachute or parachutes. For human skydiving, it may involve a phase of more or less free-falling (the skydiving segment) which is a period when the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. For cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the lower atmosphere of Earth, or be significantly delayed, such as in a planetary atmosphere where an object is descending "under parachute" following atmospheric entry from space, and may begin only after the hypersonic entry phase and initial deceleration that occurs due to friction with the thin upper atmosphere. History Common uses Parachuting is performed as a recreational activity and a competitive sport, and is widel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PZL-Mielec M-18 Dromader
The PZL-Mielec M-18 ''Dromader'' (Polish: "Dromedary") is a single engine agricultural aircraft that is manufactured by PZL-Mielec in Poland. The aircraft is used mainly as a cropduster or firefighting machine. Development PZL-Mielec, then known as WSK-Mielec, began to design the Dromader in the mid 1970s, with help of United States aircraft manufacturer Rockwell International. PZL-Mielec asked for Rockwell's help because of the political situation at the time: operating in an Eastern Bloc country, PZL wanted the aircraft to sell well worldwide, and the company realized that certification by the United States Federal Aviation Administration would be important in reaching that goal. Rockwell on the other hand wanted to fit Polish high-power radial engines into its agricultural planes. As a result of this cooperation the Rockwell Thrush Commander aircraft was fitted with the PZL-3 engine, and the Polish designers created the higher payload M-18 Dromader by introducing the more power ...
