Pelican Air
Pelican Air Services was a trading name of Federal Air, an airline based in Johannesburg, South Africa. It now trades under the name Federal Air, and no longer uses the Pelican Air branding. It operated scheduled services. Its main base was O.R. Tambo International Airport, Johannesburg, with hubs at Vilankulo Airport, Mozambique and at Kruger Mpumalanga International Airport. History The airline was established by PWD Farquhar in the late 1990s in association with TTA Mozambique. In 2001 JF Pienaar joined the company (PWD Farquhar (67%) and JF Pienaar (33%)) and had 19 employees (at March 2007). Destinations Pelican Air Services operated services from Johannesburg to Vilanculos, and onto the Bazaruto Archipelago in association with Mozambique airline, ASAS de Moçambique. Fleet As of 29 November 2009 the Pelican Air Services fleet included:Flight International, 3–9 October 2006 *1 ATR 42-320 (which was operated by Solenta Aviation) References Defunct airl ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference ( voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \text\Omeg ...

Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in ...

Leyland P76
The Leyland P76 is a large car that was produced by Leyland Australia, the Australian subsidiary of British Leyland. Featuring what was described at the time as the "standard Australian wheelbase of 111 inches", it was intended to provide the company with a genuine rival to large local models like the Ford Falcon, the Holden Kingswood, and the Chrysler Valiant. But, due to the first real fuel crisis and demand far exceeding the supply, Leyland rushed the assembly process with the first of the P76s to come off the assembly line, resulting in poor build quality and some reliability problems. The combination of the rushed assembly, fuel crisis and strikes at the component manufacturers' factories, resulted in the Leyland P76 being labelled a lemon, despite being named ''Wheels'' Car of the Year in 1973. By 1974, sales of the P76 had slumped and BMC decided to end the production of the P76. Although the P76 has been labelled a lemon in Australian motoring history, it is viewed by some ...

RPG-7
The RPG-7, is a portable, reusable, unguided, shoulder-launched, anti-tank, rocket launcher. The RPG-7 and its predecessor, the RPG-2, were designed by the Soviet Union, and are now manufactured by the Russian company Bazalt. The weapon has the GRAU index (Russian armed forces index) 6G3. The ruggedness, simplicity, low cost, and effectiveness of the RPG-7 has made it the most widely used anti-armor weapon in the world. Currently around 40 countries use the weapon; it is manufactured in several variants by nine countries. It is popular with irregular and guerrilla forces. Widely produced, the most commonly seen major variations are the RPG-7D (десантник – ''desantnik'' – paratrooper) model, which can be broken into two parts for easier carrying; and the lighter Chinese Type 69 RPG. DIO of Iran manufactures RPG-7s with olive green handguards, H&K style pistol grips, and a commando variant. The RPG-7 was first delivered to the Soviet Army in 1961 and deployed ...

Yakovlev Yak-7
The Yakovlev Yak-7 (; NATO reporting name: Mark)Jane's All the World's Aircraft 1955-56 p. 188 was developed from the earlier Yak-1 fighter, initially as a trainer but converted into a fighter. As both a fighter and later reverting to its original training role, the Yak-7 proved to be a capable aircraft and was well liked by air crews. The Yak-7 was simpler, tougher and generally better than the Yak-1.Taylor 1985, p. 122. Design and development In 1939, Alexander Yakovlev designed a tandem-seat advanced trainer, originally designated "I-27" and then "UTI-26", offered along with the original I-26 proposal that became the Yak-1. The "UTI" (''Uchebno Trenirovochnyi Istrebitel'', translated as: Training Fighter) was intended to give pilots-in-training experience on a high-performance aircraft before transitioning to a fighter. With development work started in 1940, the UTI-26 differed from its predecessor in its larger span wing being placed farther back for balance as well as havi ...

Rocket-propelled Grenade
A rocket-propelled grenade (RPG) is a shoulder-fired missile weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front. RPGs with high-explosive anti-tank (HEAT) warheads are very effective against lightly armored vehicles such as armored personnel carriers (APCs) and armored cars. However, modern, heavily-armored vehicles, such as upgraded APCs and main battle tanks, are generally too well-protected (with thick composite or reactive armor) to be penetrated by an RPG, unless less armored sections of the vehicle are exploited. Various warheads are also capable of causing secondary damage to vulnerable sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
