    [0003] CONTEXT
    [0004] Dynamic air turbines are typically used in an aircraft to provide supplemental and / or emergency power to the aircraft by using air flow to spin a turbine. Dynamic air turbines can provide electrical or hydraulic power. Electric dynamic air turbines produce electrical power by transferring rotational energy from the turbine to a generator. Dynamic air turbines can be located in a forward section of the aircraft such as the nose, for example. Dynamic air turbines can also be located in a rear section of the aircraft such as a tail, for example. Dynamic air turbines can be retracted when not in use and deployed when power is desired. In this regard, dynamic air turbines may include an actuator to deploy and retract the turbine. Actuators can have integrated hydraulic circuits that are designed to specific sizes. Current deployment actuators can be difficult and / or expensive to make to specified dimensions.
    [0005] ABSTRACT

The first dowel interface and the first threaded hole can be configured to interface with a solenoid housing. A second side of the body can be orthogonal to the first side. The second side may comprise a circular geometry with a cylindrical member disposed centrally in the circular geometry. A button assembly interface can be recessed in the second side and disposed within the cylindrical member.
    [0007] In various embodiments, the first peg interface may have a peg hole and a peg protruding from the peg hole. The dowel can be configured to rest in the dowel hole.

    [0028] Returning to Figures 3A and 3B, the peg interface 219 and the peg interface 218 may have similar configurations or may vary as described above. Threaded holes 216 can be formed by making a cylindrical opening in the body 206 and inserting a helical coil 217 into the cylindrical opening. The threaded holes 216 can receive threaded fasteners to couple a solenoid housing to the actuator housing 200. The interface hole 220 can be defined in the surface 222 of the body 206 and can be formed to interface with a solenoid housing. . Interface hole 220 has a solenoid housing location 221 upon which a coupled solenoid housing sits. The relative positions of the threaded holes 216, the dowel interface 218, the dowel interface 219, and the interface hole 220 are fixed with respect to each other to ensure an accurate interface with the interface of the machine. solenoid housing 208 at the solenoid housing location 221. In this regard, the threaded holes 216, the pin interface 218, the pin interface 219, and the interface hole 220 may have a position consistent with each other but may be placed in a different location from other parts of the actuator housing 200 such as the switch interface 210.
