I could do the math on this but I am presenting it as it was developed.

These MECHANISMS for deploying the canopy are drawn as they were originally conceived. The size of the canopy was not considered at that time past a general estimate which said it must be very large and therefore very light. Roughly 1000 times maximum area to of the plane to achieve drag to weight ratio much greater what started Skylab into it's fast descent at about 75 miles up. The method of deploying such a large canopy was the most important factor that interested in working on the design. The first part that will be explained is the parts of this design. The next will be the method for opening and deploying the canopy or parachute. This canopy was to be as light as possible and another factor to consider was the thinness of the air pushing against the canopy as it was opening The answers were that the canopy must be opened up slowly and in organized arrangement that could be altered to fit slower movement and spreading of the canopy in the thinner thin. This design was to be a part of a near 100% loss of computer and electrical power and no engine power landing the plane. The canopy is then to be larger then needed for a ship just orbiting at a altitude of 100 miles. Solar wind and solar sail would require a much larger canopy but that was not looked into at that time. But one can never make something bigger but one can just use less of something. There are other uses I worked at using deployment MECHANISM for one was a hydrogen gather in space that uses a different shaped canopy to trap (not loss free trapping) the hydrogen.
Viewing from the front of the plane the drawing above is of the contents of the right top vertical stabilizer. This is the canopy / parachute MECHANISM setting where it would inside the vertical stabilizer. The bracing that keeps the MECHANISM from tipping either what would be as seen toward or away from two sources. The 18 inch wide back wall of the vertical stabilizer and the mounting bracket motors that control it. Missing in these drawing of the vertical stabilizer and MECHANISM is the brace that runs down at a 45 degree angle from the top FRAME to where it is attached to the frame of the plane. The part of the canopy itself that can be seen is the blue that is behind the two ASSEMBLIES that release the lines to the canopy. Again viewing from the front the drawing below is of the contents of the left vertical stabilizer. These are views of the two MECHANISMS are as they face each other. In the picture blow the large gray part with the dark gray band across at the top of the picture is the tray & boot that will receive the rack and the first ASSEMBLY from the other side. When the MECHANISM is ready to deploy the canopy there will be one assembly on the top of each MECHANISM in both vertical stabilizers. There is one small 1/8 steel cable tucked into what would have been just a seams etc to allow for the arrangement to work. YOU CAN TRY TO FIGURE OUT WHAT ALL THE PARTS DO HERE NOW IF YOU LIKE.
The RED line on the picture above shows the single cables position on the fuselage of the plane. The cable goes down the inside of the vertical stabilizer, then is tucked into what would have been just a seam and then into the area just ahead of the flaps then back to what would have just been a seam to the clam shell seam and across to the other side and so on. A faile flips out from inside the vertical stabilizer to pull the line free. Pulling from this position it will pull the line free to about the middle of the flaps. The GREEN line's is the final position of the line and in the middle of the plane it is very close to where the line is tucked in at.

Fix picture screw should be in front!

The first view here is of the other side of the main mechanism with canopy or parachutes and the ASSEMBLIES removed. The two motors with screwdrives motors outlined in purple open the vertical stabilizer for deployment of the canopy or parachute. In flight they serve to trim the airplane and in emergency engines are shutoff and all for are opened to true the planes flight. Not allot of use but I would not consider a flight without them. Outlined in orange is the screwdrive motor assembly which raises the mask up out of the vertical stabilizer. The pistons have a dark blue rectangle on them; they are C shaped opened on the side toward the assembly as is the sleeve they slide in. THE GUIDES FOR THE PISTONS AND THE ASSEMBLIES ARE SHOWED WITH BOTH SIDES OPEN, SO THE POSITION OF THE INSIDE PARTS CAN BE SEEN. The cable that goes down the inside of the vertical stabilizer is moved out from behind the vertical surface and pulled free from the seams to about the far side of the flaps by a faile. The release for the faile is outlined in light green. Any other type of MECHANISM for this job would be heavier and more complicated. The rack which is red in this picture is then drawn across. The rack was just a line of spools to which held a series of heavier lines that bear most of the load on the first stage of the canopy release. The ASSEMBLIES are layers of grids of spools. Attached to the other side of the rack in two sets of cables. The lines connected near the ends of the rack are connected to the two motors and spools that are outlined in red and yellow. The motors are needed to draw the tension on the cable so that cables catch on their respective catches outlined in light yellow. This preloading of the MECHANISM means that the load that the cables will bear, will only be on the cable between the catches. (Note: This is was to be done only by what could be seen from cabin. Back off on the cable on the spool a little with the motor if cable goes slack the cable didnot catch. Pull tight again.) That why there is a motor and spool for each cable. The motor not outlined by the light blue or brown is connected to the screwdrive that brings the second ASSEMBLY over. So that it can be moved up into position. The motors outlined in light blue and the brown are covered in the next section.

Once in space the canopy or parachute MECHANISM could be advanced to this point.
The motors used up to this point could be removed.(except the last)


It is easier to show these two parts separately then to try and point them out in the picture. The first is the elevator that raises the two ASSEMBLIES into position. The second is the elevator that brings the canopy out. The vertical screwdrive raise the nose first and the other screwdrive pushes canopy out. This is all done at zero G so it is just a matter of putting something canopy in motion. The motor outlined in brown above is the motor powering the paddle that moves it across.

This picture of the other side of the MECHANISM that faces the other mechanism. The other line goes to pulley on the rack and back to the FIRST ASSEMBLY that it will pull over. This motor and spool are outlined in blue. The four black latch/rail guides pictured here are a part of the two large ASSEMBLIES that are not pictured here. The ASSEMBLIES lock to the black & gray latch catches on the shelf pictured in light gray. The black squares contain a row of pins that are pushed out by spring. The area in gray is on of two sets of little T beams the other set is on the ASSEMBLIES facing the other way. The pins come out and lock the ASSEMBLY to the shelf. This method allows the stress to be spread out over a wider area.

Above is the view of the off MECHANISM facing the main MECHANISM and below is the back of the off MECHANISM. The purple outlined motors again to open the vertical stabilizer. The light green outlined release for the faile to pull the cable free from the seam. This is pulling almost right straight up the seam not across the edge roughing the edge up. The spool and motor outlined in blue in the picture below are what draws the first cable over to the boot. Following the cable up one can see it passes right through the center line of the boot on the end with the wide opening. The tray will be cover in it's own set of pictures.
Outlined in orange is the screwdrive motor which raises the mask up out of the vertical stabilizer. The pistons have a dark blue rectangle on them; they are tube shape as are the sleeves they slide in. THEY ARE PICTURED HERE OPEN ON BOTH SIDES SO THE PARTS INSIDE AND ON THE OTHER SIDE CAN BE SEEN.

These three pictures are of the tray what I refer to as its boot. The boot is the wide end closest to where the first or feed cable comes in. That means that end will be closer to where it should be than the other over end, pull from center where will the ends be etc. The first two pictures show the back and an overhead of the tray and boot area. The motor can be seen best in the overhead second picture behind the boot on the left side. This motor drives the four gears that can be seen in the first two pictures. These hold the screw the four bolts that hold the rack in place. What started as just something to hold the first stronger set of lines while during the first part of deployment, now is a part of the system to hold the assembly in place. The last picture shows the openings for the feed cable and the four bolts.

The first of these two pictures is with the shelf on. The second is with the shelf off so that you can see the two triangles of sheet steel that are colored two different shades of gray. These triangles are spring loaded, as are the legs which bring the shelf up into position. There are pins in the sheet steel triangular braces to lock into the shelf when it is extended out. This bracing system was designed to be used on the off MECHANISM to help in guiding the rack into the boot. It was so good as far a strength and bearing the load I went ahead and used it on the other side.

The drawings above and below are with the Structure extended. The shelf is not up but the legs to them have extended. Not picture yet is the extended locks. The locks bear the load when the structure is extended and release at end of use. This is what was so handy about the shelf arrangement, at the bottom of the shelf bracing is the prefect place for the locks to be. The bracing is across the joint in the in the structure of the ASSEMBLY. The length of travel is open around the outside of the vertical member. But when extended everything is locked back through to the legs of the head. (All the vertical tracks is closed on the side toward the other MECHANISM it only appears open so the position of the track guides is visitable and kept in mind.)

Major factors effecting the center of gravity of the plane are engine for space and it's assembly, the back wheel assemblies and the MECHANISMS to deploy the canopy for reentry the earths atmosphere. The center of gravity after dumping most of the fuel is about 15-20 feet forward of the anchor point and the height of the mask over the center line of the plane is 11 feet, incase would like to figure the initial angles involved.

The power for the motors and the firing off of the spools in the racks and ASSEMBLIES is all handled by relays and transistors, the power delivered by large cables.(All not pictured here) All the wires for the relays and transistors for the canopy system are redundant. The main power cables that supply the power though tout the plane are in a overhead conduit that runs the length of the fuselage. The redundant cable is along the rightside of the plane. The feeder cables run out into wings crawlway out to the engine one on each side. The cables then goes back along the engine and to the top of the engine to this assembly. The cables does go down the other side to the outside control surface. The inside control surface is powered by the almost direct connection to the main power cables in the fuselage. The amount of trunk lines for the electricity needed for this plane is large but in constructing a sphere most large cables can be reused or operation of the electrical system later.
