A
brake stack comprises a
stator having an annular, inner periphery section disposed substantially along a first
radial plane extending normal to an axis of a wheel, and a
stator side wall having a first
stator contact surface, the first stator contact surface including a sloped portion which deviates away from the
radial plane defined by the annular, inner periphery section. The
brake stack further comprises a rotor having an annular, outer periphery section disposed substantially along a second
radial plane extending normal to the axis of the wheel, and a rotor side wall having a first rotor contact surface shaped complementary to the first stator contact surface, wherein the stator and the rotor are interleaved.A
brake disk may comprise a first
radius of a friction surface at a first axial position and a second
radius of the friction surface at a second axial position, where the first
radius is different than the second radius. The brake disk may further comprise an axis of rotation orthogonal to a plane of rotation, wherein the brake disk rotates substantially in the plane of rotation, and wherein the friction surface is at an
acute angle to the plane of rotation.An aircraft brake
system comprises an aircraft rotor oriented orthogonally with respect to an axis of rotation and an aircraft stator configured to
nest with the aircraft rotor, where a stator friction surface is non-orthogonal to the axis of rotation. The aircraft brake
system may further comprise a pressure plate and an end plate configured to
nest with the aircraft rotor and / or aircraft stator, and an
actuator may be utilized to effectuate braking of the aircraft
braking system.
