To reduce vibration, all helicopters have rotor adjustments for height and weight. A maladjusted helicopter can easily vibrate so much that it will shake itself apart. Blade height is adjusted by changing the pitch of the blade. Weight is adjusted by adding or removing weights on the rotor head and/or at the blade end caps.
The investigation determined that the helicopter lost yaw control due to failure of flight control computer. On 29 May 2001, a Republic of Korea Army (ROK Army) CH-47D installing a sculpture onto Olympic Bridge in Seoul, South Korea failed to unlatch the sculpture. The helicopter's rotors struck the monument; then the fuselage hit and broke ...
The helicopter was designated "CH-53A Sea Stallion" and delivery of production helicopters began in 1966. [5] The first CH-53As were powered by two General Electric T64-GE-6 turboshaft engines with 2,850 shp (2,125 kW) and had a maximum gross weight of 46,000 lb (20,865 kg), including 20,000 lb (9,072 kg) in the payload.
The first Made-in-India helicopter with EASA-certified quality assurance will be delivered in 2026. [13] Ten helicopters will be manufactured each year at final assembly, with the number of units produced gradually increasing to 20, 30, or 50 in the future. As of now, 500 units is expected to be produced in 20 years.
The new design was required to have an empty weight less than half its maximum takeoff weight. [3] The helicopter was designed by Marat Tishchenko, protégé of Mikhail Mil, founder of the OKB-329 design bureau. [4] Cockpit of a Mil Mi-26
In December 2020, the H135 helicopter family EASA has certified a new Alternate Gross Weight (AGW). With the new AGW, the maximum takeoff weight has been increased up to 265 lb (120 kg) and payload. This modification can be used to increase range by up to 75 nm or endurance by up to 40 minutes under standard conditions.
The center of gravity is even more critical for helicopters than it is for fixed-wing aircraft (weight issues remain the same). As with fixed-wing aircraft, a helicopter may be properly loaded for takeoff, but near the end of a long flight when the fuel tanks are almost empty, the CG may have shifted enough for the helicopter to be out of ...
