Systems and methods are provided for an ice detector with a movable airfoil. The movable airfoil may be airfoil shaped and the ice detector may include an ice detection sensor. The movable airfoil may be adjusted in angle of attack and/or configuration to simulate the pressure gradient experienced by one or more of the wing, fuselage, engine, horizontal/vertical stabilizer, or other component of the aircraft. Sensors may be used to detect the configuration of the aircraft or the components of the aircraft and the configuration of the movable airfoil may then be adjusted to approximate the pressure distribution around the aircraft component. Ice accretion on the movable airfoil may be determined via the data from the ice detector.

Aircraft ice detection systems and methods

A wheel assembly for use with a vehicle is provided. The wheel assembly includes a first inner wheel portion, a second inner wheel portion positioned adjacent to the first inner wheel portion, a first wheel bladder coupled to the first inner wheel portion, and a second wheel bladder coupled to the second inner wheel portion.

Wheel system for a vehicle

Systems and methods for separating contaminants in a contaminated airstream are described. In one embodiment, a contaminated airstream is received and a vortex is created that separates the contaminated airstream into a clean airstream used in the system and contaminants (e.g., debris and particles).
