Denel SARA
The Denel SARA (Small African Regional Aircraft) is a projected 24-passenger turboprop regional airliner with rough field capabilities. The project was announced at the Africa Aerospace and Defence exhibition in September 2014, by the state-owned defence industrial group Denel. The project has a goal of permitting landings at fields with runways shorter than 1,000m, of which there are more than 460 in South Africa alone. Design and development The SARA project originated in 2012 when a SARA Steering Committee, co-chaired by the CEOs of Denel Aerostructures SOC Ltd and Denel Aviation, was set up. Various options were considered. A high wing configuration was selected for SARA to meet the issue of foreign object debris, for example stones thrown up by the propellers during landing, taking off and taxiing. SARA will have a degree of STOL capability, but will not be optimised for STOL operations as it affects other performance parameters negatively. It will be certified under Part 25 ...

Turboprop
A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the Fuel mixture, fuel-air mixture then Combustion, combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Regional Airliner
A regional airliner, commuter airliner or feeder liner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feeder liner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines. Examples included the De Havilland Dragon Rapide biplane and the Douglas DC-3s, in large surplus after the war, which the a ...

Africa Aerospace And Defence
The African Aerospace and Defence Expo (AAD) is an aerospace and defence exhibition held every two years at AFB Waterkloof, in Centurion, Gauteng, South Africa. The exhibition combines a trade exhibition and an air show. The AAD began in 1975 when the South African based aviation magazine World Airnews determined that a professional aerospace exhibition was appropriate, as distinguished from the traveling "barnstorming" air shows that were then prominent. The first event was held October 1975 as "Aviation Africa", at Lanseria Airport near Johannesburg, South Africa under the sponsorship of the Commercial Aviation Association of Southern Africa. The same year, Lt. General Bob Rogers of the South African Air Force instituted an open day at AFB Waterkloof, in Centurion, which eventually turned into the Defence Exhibition of South Africa (DEXSA). In 2000, Aviation Africa and DEXSA combined to become AAD. In 2006, the exhibition moved to AFB Ysterplaat in Cape Town Cape Town ...

Denel
Denel SOC Ltd is a South African state-owned aerospace and military technology conglomerate established in 1992. It was created when the manufacturing subsidiaries of Armscor were split off in order for Armscor to become the procurement agency for the South African Defence Force ( SADF), now known as the South African National Defence Force ( SANDF), and the manufacturing divisions were grouped together under Denel as divisions. It is the largest of South Africa's state owned arms companies. The company had been experiencing major financial problems since 2015 and in 2021 it was announced in Parliament that Denel was on the brink of insolvency. The company stated that its woes were due to declining local defence budgets, weakened relationships with key customers and suppliers, the inability to retain or attract skilled personnel, ongoing salary disputes and a Fitch ratings downgrade.

Foreign Object Debris
In aviation and aerospace, the term foreign object damage (FOD) refers to any damage to an aircraft attributed to foreign object debris (also referred to as "FOD"), which is any particle or substance, alien to an aircraft or system which could potentially cause damage to it. External FOD hazards include bird strikes, hail, ice, sandstorms, ash-clouds or objects left on a runway or flight deck. Internal FOD hazards include items left in the cockpit that interfere with flight safety by getting tangled in control cables, jam moving parts or short-out electrical connections. To jet engines Jet engines can suffer major damage from even small objects being sucked into the engine. In the United States, the Federal Aviation Administration (FAA) requires that all engine types pass a test which includes firing a fresh chicken (dead, but not frozen) into a running jet engine from a small cannon. The engine does not have to remain functional after the test, but it must not cause signifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
STOL
A short takeoff and landing (STOL) aircraft is a fixed-wing aircraft that can takeoff/land on short runways. Many STOL-designed aircraft can operate on airstrips with harsh conditions (such as high altitude or ice). STOL aircraft, including those used in scheduled passenger airline operations, can be operated from STOLport airfields that feature short runways. Design STOL aircraft come in configurations such as bush planes, autogyros, and Conventional landing gear, taildraggers, and those such as the de Havilland Canada Dash-7 that are designed for use on conventional airstrips. The PAC P-750 XSTOL, the Daher Kodiak, the de Havilland Canada DHC-6 Twin Otter and the Wren 460 have STOL capability, needing a short ground roll to get airborne, but are capable of a near-zero ground roll when landing. For any plane, the required runway length is a function of the square of the stall speed (minimum flying speed), and much design effort is spent on minimizing this number. For take ...

Federal Aviation Regulations
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (14 CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, human-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, unmanned aircraft systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. FAR vs. 14 CFR Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisition Regulations", and this has led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Maximum Takeoff Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. It refers to the maximum permissible aircraft weight at the start of the takeoff run. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or the length of the runway to be used for takeoff or landing. Maximum permissible takeoff weight or "regulated takeoff weight", varies according to flap setting, altitude, air temperature, length of runway and other factors. It is different from one takeof ...
