Abstract

An actuator housing is provided. The actuator housing may comprise a body, and a first side of the body including a first pin interface and a first threaded hole clocked relative to the first pin interface. The first pin interface and the first threaded hole may be configured to interface with a solenoid housing. A second side of the body may be orthogonal to the first side. The second side may include a circular geometry with a cylindrical member disposed central to the circular geometry. A toggle assembly interface may be recessed in the second side and disposed within the cylindrical member.

First claim

What is claimed is:

1. A ram air turbine (RAT) having an actuator to deploy and stow the RAT, the actuator having an actuator housing, comprising:
a body;
a first side of the body comprising a first pin interface and a first threaded hole clocked relative to the first pin interface, wherein the first pin interface and the first threaded hole are configured to interface with a solenoid housing;
a second side of the body orthogonal to the first side and comprising a perimeter having a circular geometry and a cylindrical member recessed in the second side and central relative to the perimeter, wherein a plurality of threaded holes are disposed in the second side and about the cylindrical member; and
a toggle assembly interface disposed within and extending from a bottom of the cylindrical member, wherein the toggle assembly interface comprises a second threaded hole and is configured to receive a toggle assembly.

2. The actuator housing of claim 1 , wherein the first pin interface comprises:
a pin hole; and
a pin protruding from the pin hole.

3. The actuator housing of claim 2 , wherein the pin is configured to bottom in the pin hole.

4. The actuator housing of claim 3 , wherein the pin comprises diamond dowel.

5. The actuator housing of claim 1 , wherein the first threaded hole comprises a helical insert.

6. The actuator housing of claim 1 , wherein the toggle assembly interface further comprises:
an interface hole aligned with the second threaded hole; and
a second pin interface.

7. The actuator housing of claim 1 , wherein the second side comprises a plurality of third threaded holes disposed about the cylindrical member.

8. The actuator housing of claim 1 , further comprising a pin interface disposed on the second side radially outward from the cylindrical member.

9. A ram air turbine (RAT), comprising:
a housing;
a strut coupled to the housing;
a turbine at a distal end of the strut; and
a deployment actuator secured to the strut and the housing, the deployment actuator comprising:
an actuator housing comprising a body,
a first side of the body comprising a first pin interface and a first threaded hole clocked relative to the first pin interface, wherein the first pin interface and the first threaded hole are configured to interface with a solenoid housing,

a second side of the body orthogonal to the first side and comprising a perimeter having a circular geometry and a cylindrical member recessed in the second side and central relative to the perimeter, wherein a plurality of threaded holes are disposed in the second side and about the cylindrical member; and
a toggle assembly interface disposed within and extending from a bottom of the cylindrical member, wherein the toggle assembly interface comprises a second threaded hole and is configured to receive a toggle assembly.

10. The RAT of claim 9 , wherein the first pin interface comprises:
a pin hole; and
a pin protruding from the pin hole.

11. The RAT of claim 10 , wherein the pin is configured to bottom in the pin hole.

12. The RAT of claim 10 , wherein the pin comprises a pin head having a polygonal geometry.

13. The RAT of claim 9 , wherein the first threaded hole comprises a helical insert.

14. The RAT of claim 9 , wherein the toggle assembly interface further comprises:
an interface hole aligned with the second threaded hole; and
a second pin interface.

15. The RAT of claim 9 , further comprising a pin interface disposed on the second side of the body and radially outward from the cylindrical member.
