Has anybody gone into the technical side of the launching procedure of Sky One? To make the submarine tilt upwards at 45 degrees would be simply a matter of blowing the forward ballast tanks, but what happens when Sky One detaches from the main body? With the aircraft free, one would expect the rest of the vessel to go to a vertical position, (with the crew holding on for dear life) but the launch sequence shows it remaining stationary. One way to keep the equilibrium would be for the aircraft section to carry,then jettison it's own ballast,but this would be contrary to the design of any craft,as I have heard that what applies for air also applies to water,such as drag.Any sort of ballast would certainly have an effect on the aircraft both in the water or out of it. Any thoughts? Regards,Kevin |
Hi All :)

Good point, how about...(bear in mind I am not an engineer!) 1) maneuvering thrusters kick in as Sky 1 detaches to keep Diver in the same position until the ballast is adjusted. 2)a counterweight can be moved quickly from aft to bow by hydraulics or somesuch method. 3)Sky 1's rockets are first exhausting into Diver perhaps these gases can be used to adjust aft trim tanks? What do you think? Barry |

Thankyou very much for the wish to all of as but know that not all of us will have that wealth and happiness but will have sruggles looking for school fee like am.

It looks an easy task to launch Sky One, but the more I think of it the more complicated it gets. Kevin |

If so,I assume these would come in handy for aligning and reattaching the plane to the submarine section. Unfortunately, we never get to see this task carried out during the series.It may have been a big job. Kevin. |

I first used to think that it would be done by ditching the plane and then winching it back against the surfaced sub. But on anything less than a calm day, wave action would make that terribly hazardous, so it seems best to re-link them well below the surface of the water, where wave action is no longer felt. Small water jet maneuvering thrusters would allow the pilot to back the plane up against the submarine and re-dock.....but at a terrible weight penalty on an already impossible airplane. An alternative would be to let the plane settle to a prescribed depth, then dispatch scubadivers to cable and winch the plane back against the docking ports of the sub. The weight cost of a simple air ballast tank filling already available air voids within the plane's fuselage would be minimal. The plane could be always maintained as neutrally bouyant on the submarine, therefore, no need to have all these fancy counterballancing thrusters and moving counterweights. Dave H. |

...possibly SkyDiver had a reinforced back bumper and heavy-duty wheelie bars. croprobz <[hidden email]> wrote: --- In [hidden email], "davrecon" wrote: > > How about.... just trimming the boat and plane to be neutrally bouyant in > both configurations.
