Abstract

An actuator housing is provided. The actuator housing may comprise a body. A first side of the body may include 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 the body may be disposed adjacent the first side. The second side may include a toggle assembly interface configured to receive a toggle assembly. A third side of the body may be disposed adjacent the first side and the second side. The third side may include an adapter interface configured to receive an adapter for the toggle assembly.

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, the body having;
a first side of the body comprising an interface hole, a first pin interface, and a first threaded hole with the interface hole and the 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, wherein the interface hole has an asymmetric geometry;
a second side of the body orthogonal to the first side and comprising a toggle assembly interface configured to receive a toggle assembly, wherein the second side of the body comprises a plurality of second threaded holes, an interface hole between the second threaded holes, and a second pin interface, wherein the second threaded holes and the second pin interface are clocked relative to the interface hole;
a third side of the body orthogonal to the first side and the second side, wherein the third side comprises an adapter interface configured to receive an adapter for the toggle assembly; and
a mounting appendage extending from the body and configured to retain a bearing.

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 adapter interface comprises:
a plurality of second threaded holes;
a plurality of second pin interfaces; and
an interface hole central to the second threaded holes.

7. 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 adjacent the first side and comprising a toggle assembly interface configured to receive a toggle assembly, and
a third side of the body adjacent the first side and the second side, wherein the third side comprises an adapter interface configured to receive an adapter for the toggle assembly.

8. The RAT of claim 7 , wherein the first pin interface comprises:
a pin hole; and
a pin protruding from the pin hole.

9. The RAT of claim 8 , wherein the pin comprises diamond dowel configured to bottom in the pin hole.

10. The RAT of claim 7 , wherein the first threaded hole comprises a helical insert.

11. The RAT of claim 7 , wherein the toggle assembly comprises:
a plurality of second threaded holes;
an interface hole between the second threaded holes; and
a second pin interface.

12. The RAT of claim 7 , wherein the adapter interface comprises:
a plurality of second threaded holes;
a plurality of pin interfaces; and
an interface hole between the second threaded holes.

13. The RAT of claim 7 , further comprising a mounting appendage extending away from the body opposite the second side, wherein the mounting appendage is coupled to the housing.
