Aviation History – Chapter 2.5 – Lockheed C-5 Landing Gear

I’ve been doing research for the next post on air refueling, which should be up in a couple of days. In the process I found these two videos which  show the operation of the Lockheed C-5 landing gear.  I tried to describe the operation in words in my last post covering some of the unique features of the C-5 but I don’t think the words  described the contortions very well. This is another instance where a picture (video) provides a much clearer description.

The first video is actually an animation developed using a flight simulator program. It is titled “30-knot crosswind”, but it starts out showing the aircraft on the ground with the aircraft kneeled, the forward and aft cargo doors open and the ramps extended. The animation closes the ramps and doors and un-kneels the aircraft, then moves the aircraft to the runway for a takeoff. The landing gear retraction sequence is shown clearly. The video goes on to make a landing or two, ending with one it says it is with the strong crosswind. I had hoped to see the crosswind gear in operation, put it is not evident.

The second video runs a little bit longer and was taken at an open house airshow at the Dover, Deleware C-5 base. The aircraft takes off and makes several fly-bys, with and without landing gear operation and then makes a short-field landing, stopping in front of the crowd. If you listen closely you can hear the airshow announcer describing the aircraft. The video provides a good view of the aircraft in flight and allows you to hear the unique sound associated with the C-5 engines.

Globe Swift Landing Gear Rebuild – Actuator

In the last post we talked about replacing the seals in the Globe Swift landing gear downlock. This post will cover some of the steps in replacing the seals in the landing gear actuator. As mentioned in the last post, actuator seal kit S-147 was purchased from the Swift Association to complete this actuator rebuild.

Globe Swift Landing Gear Rebuild – Downlock

The Manual

Globe Swift Hydraulic Manual The main landing gear downlock is the simplest of the hydraulic mechanisms on the Swift to rebuild, but it still is best accomplished with a copy of the Swift Hydraulic Manual. It may be purchased from the International Swift Association, Athens, TN.  In it are parts breakdowns and step-by-step instructions for the overhaul of all of the Globe Swift hydraulic components. The Swift Association also has a Parts Store which sells pre-packaged seal kits for the various hydraulic components.  I have listed for your reference the kits that I purchased when I began my hydraulic rebuild project, but check with the Parts Store representative when you make your order.

 

Downlock seal kit:                           S-148

Actuator seal kit:                             S-147

Adel Gear Strut seal kit:                   S-145

Adel Gear Strut bolt & bushing kit:  S-144

Flap Cylinder seal kit:                      S-150

Tailwheel Strut seal kit:                   S-149

Brake Master Cylinder seal kit:        S-151
