Roll prevention control for aircraft - has individually driven spoilers on outboard wings to compensate for failure of one engine

摘要

The control operates to prevent the rolling of an aircraft having an even number of propulsion units, when one of the propulsion units stops operating due to a breakdown. Spoilers are mounted on the outboard wings. Each spoiler has an individual drive connected to a power circuit via a control valve which, in turn, is functionally associated with a failure detector of the propulsion unit disposed on the outboard wing opposite to that on which the respective spoiler is mounted. The apparatus is brought into action automatically, to counteract the rolling tendency of an aircraft when one of its propulsion units fails. A manual control can correct the glide path during landing, dissipating the lift and applying the aerodynamic braking during the landing roll.
