Shuttle's first wheels off, in space, assembly taken out for an airlock in the compartment

The whole front wheel assembly that can be removed once in space to allow for the installation of an airlock. The use of the front wheel compartment for this would mean there would be no need for a special door opening or compartment for the airlock. The doors already have to be sealed though not as well as for use as an airlock. This wheel assembly is to be of the lightest construction possible that I could come up with, this is not designed for landing and taking off anywhere near as much as even a light plane would. The plane itself is not made to function as a commercial jet might.

I will begin as the design started I withhold all rights for myself and my use but you can use it for mental exercise and stop and think if you like.

This was the first development. The length was such that it needed to be foldable and then be able to fold up and be put away The three picture in the middle at what happened lets go this way lets try this way. Back and fore it went. When I started this page I knew I had a front wheel assembly that folded up. More what are all the thing that have to happen. Ok, when it is on the ground it cannot fold back. It will take many steps to make it work right. Little facts and thing that your mind will not want to do. Like a wire laying on something.

There is on more sad fact there are more project then are seen because of what I just said, they do not seem to exist. But either way I will do this one as if it is one of the few and best things I have done. If I finish the plane here as before. When I would have taken of never to be seen again I would be happy.

It is simple, ugly and has to be studied before it can be seen any good, but it is mine.

This picture includes the cockpit with it's windows. One of the first thing I drew after the basic frame was the chair to sit in there. But now we can ignore that and just see it as a point of reference as to where we are in the plane. The line that is the top of the compartment the hold the front wheel assembly it the floor for the cockpit. That area is reachable from the cockpit houses equipment and emergency stores. The front of plane is divided into three sections for handling inflight emergencies. The Cockpit, the Front Wheel Assembly Area / Airlock Chamber and the Living Working Area. It is easier to work the closer one gets to something that is or works.

I will start as with the Parts List with the Cable Head Mount. This holds the Head End of Front Wheel Assembly up locked in place when in the not in use. There is the Hoist, the Motor for the Hoist and the Cable that will pull the landing gear landing gear up. The Cable Head Mount's load is carried by two frame members one is the end wall of the compartment and the other is on flange with in. The Cable does as it seem, it goes down between the wheels, this seems not ideal even now without seeing there is a valley between the wheels that will guide the cable to the channel in the bottom. The Hoist Spool and the Motor Hoist. The Motors that open and close the compartment doors on either side of the housing. The housing which will come out in space makes good base for a crane or wench. It is for this reason the amount of cable on the spool will be what needed hoisting of the wheels plus what ever cable maybe needed for other uses.

Sperate from the housing is the two front supports for the Front Wheel assembly. The latch for the joint pull the sections inline or kicks them back to the slightly bent position. Next is the Saddle that lifts Lower Tube Portion and Wheels out of it's place when the front support starts to straighten. The Lower Mounting for Front Supports are in the form of the mast to allow the wheels to move between. This is another part needed for Landing Gear to work that seem to be too awkward.

Starting from the bottom and going up the Wheels and Tires, next the Sliding Outer Tube and the Inner Coil Spring Housing. The dark line is the Slide Range Slot for the Spring Action Stop. On take off the springs will be compressed so much as to be on the stops on the inside and near the end of the travel allowed by the groves. This is to be a gentle roll out to a takeoff. If an abort is necessary fuel will need to be dumped.

The lower portion of the Support A-Frame. This cannot be seen from here but there are Upper and Lower set of Paw and Catches the will stop the rotation of the tubular Lower Portion in this position and a servo operated latch. The cable can be seen running up the back to bottom of the Steering Gear is Cable attachment point. When the action of folding up the Landing Gear finished this will be pulled to the Cable Head Mount this side will be up. That was difficult to figure was the offset weight of the wheels would make this balancing work when coupled with the force of the air coming at it. The At the top or Head is the Steering Gear, this can be seen as the light and dark lines appearing at the on each side of the A-Frame.

The Upper Portion Support A-Frame spreads the load to the corners of the Compartment. The Corners of the Compartment have one frame member on the end and one flange width in, so the load is distributed to two frame members. The best way to work on a project is to pile up numbers and facts that means work. The best place to start is school if you are serious. If not just take it easy and do not expect to be good. Work Check Work. Keep day job. Keep it to yourself it is a hobby most thing will not work well without lots of practice. Most will think you want to be great, I really view it as a way to keep the mind in motion. Never really Bored.

This time I will start a the bottom and work my way up. The tires are not standard tires for aircraft and the hubs of the wheels airlock together to allow for a rim that can hold against higher pressure. The axle was half shaped before I realized the shape of the axle lower surface was useful. The shape is the valley that will guide the cable to the channel in the bottom. There is still the Nut and the bottom of the bolt down there but they are below the surface. The edges are rounded and the whole are polished by stone wheel. From here up we follow the nut and bolt up the coil spring. The spring is held in place by the spring retainer. On the top of the Spring Retainer is the Lower End of Throw Bumper. Standard to all spring systems is the rubber grommets at the last of the possible travel. Together with the upper part they form a ball and socket shape as you can see by the picture. The Sliding Portion Landing Gear Tube is threaded to the Upper Portion of the Axle Assembly. The Axle Assembly is composed of Upper Portion and Lower Portion; they may look as one piece because the are matching set of metal cone shapes that mate. This is how the front wheels are turned. From this view on can how much the Sliding Portion Landing Gear Tube and the Spring Housing Tube over lap. From the Coil Spring the next part is the Upper Spring Retainer. The Spring Retainer is held in place by the nut screwed on to what is the threaded bolt end of the Steering Rod. On the attached and pointing down from the Spring Retainer is the Upper Part of End Throw Bumper. There is on more part not picture a set of splined tubes the enclose the bumpers, this transmits the power down through the springs. Springs retainers and the joint in Wheel Assembly are all greased. This start as a stiff, no spring, or steering landing gear that folded into the plane. First came the steering, then the spring in that order. The order of adding ideas or needs can change how the parts come together, incase how to design is the reason your reading this. Following the Steering Rod up through the Spring & Steering Rod Housing Tube next part is the Lower Steering Rod Bearing at the other end of the tube is the Upper Steer Rod Bearing and its Retainer.

The Lower or Straight Extension of the A-Frame Support is the holds the next parts next part I will be explaining. This is of the view with the Wheels down, Lower or Straight Extension of the A-Frame Support holds all the Catches for the Wheel Assembly in both the down and up position. The Lower Load Bearing Paw that is in the Catch at the bottom will rotate forward and up into the Gear Up Lower Paw Catch (ie the black box at the top). At the top on the left is the is the Upper Load Paw & Catch as it appears from the front, on the right shows how it looks from the back. At the Head is the Steering Gear which is driven by the Steering Motor by a shaft to a small Gear. Motor in use here and as much possible through out the plane is a motor with gear reduction head on a roughly 2 Horse Power motor. Which can function as a motor or generator for many applications by use of different parts. Ie changing off the gear reduction unit or a different brush unit on the other end. In other words very light parts kept as payload or cargo. Here it is being used with another set of gears for the slow speed and high torque that is needed for this application.

The Upper Portion Support A-Frame spreads the load to the corners of the Compartment. The Shaft is thicker at the ends The flange at the end transfers part of the load to the frame member on the end of the compartment.

This view is from the bottom looking up into the compartment for the front landing gear. The light blue line is the edge of the outside door to the compartment the single gray line to the left is the inside edge of the door way into the cabin. Here on can see the Cable Head Mount with the Steering Gear Head locked in place with the Catch for Upper Paw locked in the Cable Head Mount. On down the landing gear there are two red squares these are the catch for the Lower Portion of the Landing Gear. The motors that open and close the compartment doors on either side of the Cable Head Mount. The Paws are of course on the other side and cannot be seen.

Shuttle's first wheels off, in space, assembly taken out for an airlock in compartment. When I started of working on a design for a plane to go into space in it had no landing gear. The plane took off from a catapult and I didnot plan on coming back to land on Earth. So wheels tires springs or landing gear were something that I had not thought about. People that would get assigned the job of designing landing gear would design the best they could, I just wanted something that would work. Something that is interesting is that with no plans to ever land on Earth or any where, there was little use of the term landing gear in the first writing of this page on front wheel assembly. The term landing gear was not used.

With the tool at the address below the important word and how many times they were used were obtained they are listed in the meta tag in that order. Title is picked out by importance and high ranking. Whether or not you hire a professional or not your writing should be done with this knowledge. I would recommend professional help if your using the web for your livelihood.
