Ballast Ballast is removable or permanently installed weight in an aircraft used to bring the center of gravity into the allowable range. Center-of-Gravity Limits Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during ...
The company states the design goal of the AC-6 as a glider for the competition and training roles, even though it does not have provisions for water ballast. [ 2 ] The AC-6 is a 15 m (49.2 ft) wing span development of the 12.6 m (41.3 ft) span AC-5M , with longer, higher aspect ratio wings terminating in winglets .
In aviation, manufacturer's empty weight (MEW) (also known as manufacturer's weight empty (MWE)) is the weight of the aircraft "as built" and includes the weight of the structure, power plant, furnishings, installations, systems, and other equipment that are considered an integral part of an aircraft before additional operator items are added for operation.
The 1-26A is a "standard" that was completed by the builder from a kit and licensed as a certified aircraft, instead of an amateur-built. There were 114 completed. [9] Like the "standard", the "A" also has a gross weight of 575 lbs. [6] 1-26B The "B" model was introduced in 1956 as a factory built aircraft. [6]
An aerostat (from Ancient Greek ἀήρ (aḗr) 'air' and στατός (statós) 'standing', via French) or lighter-than-air aircraft is an aircraft that relies on buoyancy to maintain flight. Aerostats include the unpowered balloons (free-flying or tethered ) and the powered airships .
Changes in weight of fuel on board, due to fuel consumption. This was a challenge especially in the large historic airships like the Zeppelins . For example, on a flight from Friedrichshafen to Lakehurst, the rigid airship LZ 126 , built in 1923-24, used 23,000 kg gasoline and 1300 kg of oil (an average consumption of 290 kg/100 km).
The aircraft is made from wood and klegcell foam. Its 7.10 m (23.3 ft) span wing employs a 15.80% thickness airfoil , has an area of 5.66 m 2 (60.9 sq ft) and mounts flaps , as well as winglets .
Ballast weight is also added to a race car to alter its performance. In most racing series, cars have a minimum allowable weight. Often, the actual weight of the car is lower, so ballast is used to bring it up to the minimum. The advantage is that the ballast can be positioned to affect the car's handling by changing its load distribution.
