A high-lift device called a flap transmission is used to lower an aircraft wing’s stall speed at a specific weight. In a fixed-wing aircraft, flaps are typically positioned on the trailing edges of the wings.
Flaps are used to shorten the distances required for takeoff and landing. They increase the camber, chord, and, in most instances, surface area of the wing when extended, which increases lift and drag while decreasing stall speed.
The global aircraft flap transmission market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For Boeing’s proposed New Mid-market Airplane, UTC Aerospace Technologies is creating new “fully-distributed” electric flap transmission and slat control systems (NMA).
The project is a part of UTAS’ larger “more electric” initiative to create electric aircraft systems in favor of outmoded hydraulic, pneumatic, and mechanical systems.
According technical lead for UTAS’s actuation and propeller systems, the UTAS flap and slat systems would employ several electric motors dispersed throughout the inside of the wing to extend or retract individual flaps and slats.T
he technology would replace the mostly mechanical systems currently found on big commercial aircraft, pioneered by UTAS’ actuation systems division in the UK city of Wolverhampton.
The electric flap transmission in the SubSonex! The motorized flap system is lightweight and portable. The throttle quadrant for the PBS TJ-100 engine is also moved to a more comfortable location in the cockpit thanks to the removal of the manual flap lever on the left-hand cockpit wall.
The potentiometer found in the 24 Volt electric flap actuator enables your EFIS avionics system to indicate the flap position.
