Abstract: Techniques are disclosed for providing retractable control fins on an underwater vehicle. The retractable control fins can be extended away from a main hull portion of the underwater vehicle and retracted inwards to a stowage region within the hull portion to protect the fins from damage and reduce an overall outer diameter (e.g., in the case of a cylindrical body) of the underwater vehicle. In some embodiments, the control fins are folded inwards to reduce the vehicle diameter. In other embodiments, the control fins are pulled inwards using a rotating structure designed to slide the control fins through an opening and into an inner portion of the hull to reduce the vehicle diameter. The retraction of the fins through the various retraction mechanisms reduces the envelope diameter of the underwater vehicle.

Abstract: A V-band clamp includes first and second clamp sections each having an arcuate shape with a first end, a second end, and inside surface defining a recessed channel. A hinge pivotably connects the second end of the first clamp section to the first end of the second clamp section. At least one fastener is configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position. When the V-band clamp is in the closed position, each fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section.
