Small Attack Submarines, Which Turn Into Hydrofoils and Fly

We propose single man underwater vehicles (attack submarines), which have inflatable Airbags using CO2 cartridges for rapid ascent. The design of these vehicles will encompass bended material, which makes rings underneath resembling typical designs of small hydrofoils. These rings will be attached at the body and extend down ward and be attached in the center to themselves. The vehicle will be propelled by an onboard that will distribute the energy to two propellers on above the vehicle and one below. The bottom propeller will be at the lower level of the connected rings. The motor will be at the feet of the laying down facing forward operator. The underwater vehicle will be shaped similar to a short winged manta ray. Once the mini submarine surfaces it will accelerate up onto the step. Like a single hulled floatplane as the speed increases it will raise up on the rings. The rings will have strakes as part of their structure throughout.

When the mini sub is ready to rise it will deploy the CO2 lever, which will expand the leading edge of the front of the manta ray mini wings, thus thrusting it up to the surface. Once the sub is above water and up on the rings it will fly and use the ground cushion to accelerate and pick up speed. The rings will release the attachment at the bottom and become thin airfoils, the front will become a canard which will be facing slightly forward ahead of where the wings become one with the fuselage allowing airflow to meet the wing, think of what we had learned with NASA and the X-29. The rear ring will become a horizontal stabilizer and use laminar flow to guide the air to the propellers, which will be automatically spun from vertical alignment to a horizontal alignment.
