Mechanical architecture for distributed flap actuation system

A distributed flap actuation system to control translation and rotation of a flap of an aircraft wing, the distributed flap actuation system comprising:

• a mechanical architecture comprising:
• a shaft;
• a first actuation unit comprising a dual channel motor receptive of electricity from first and second electrical system of the aircraft, a first actuator for translating and rotating the flap and being connected to a first side of the flap, a first gearbox to transfer and increase torque from the motor to the first actuator and a first brake for holding the flap in place, and
• a second actuation unit comprising a second actuator that receives the torque from the first gearbox via the shaft for translating and rotating the flap and being connected to a second side of the flap, a second gearbox that receives the torque from the first gearbox via the shaft and reduces the torque and a second brake receptive of the torque from the second gearbox for holding the flap in place through the second actuator.

An aircraft, comprising:

• wings extending outwardly from either side of a fuselage;
• a flap disposed on each of the wings;
• and
• a distributed flap actuation system to control translation and rotation of the flap disposed on each of the wings,
• the distributed flap actuation system for the flap disposed on each of the wings comprising a mechanical architecture comprising common mechanical blocks (CMBs), said CMBs further comprising:
• a shaft;
• a first actuation unit comprising a motor, a first actuator for translating and rotating the flap and being connected to a first side of the flap, a first gearbox to transfer and increase torque from the motor to the first actuator and a first brake for holding the flap in place, and
• a second actuation unit comprising a second actuator that receives the torque from the first gearbox via the shaft for translating and rotating the flap and being connected to a second side of the flap, a second gearbox that receives the torque from the first gearbox via the shaft and reduces the torque and a second brake receptive of the torque from the second gearbox and configured to hold the flap in place through the second actuator.
