Dive planes, also known as hydroplanes, are control surfaces on a submarine that allow the vessel to tilt the bow and stern up or down to aid in the diving or surface setting process, as well as control depth when submerged.

Submarine Sail Planes

Dive planes are usually placed in two pairs, the bow at the front of the submarine and the bow at the back. The tailplanes function in the same way as an airplane elevator. Because the planes are farther forward and aft of the fuselage's center of lift, they are brought into the pitch pole. Ballast tanks inside the submarine adjust the wheels to be neutral, which keeps the ship under control. The position of the planes controls the heel of the ship and, as the ship moves forward, it controls the depth. If not carefully controlled, this can lead to an "unreachable" motion where the aviator is constantly searching for a stable combination of depth and height.

For easier docking, submarines used folding bow planes that retracted along the hull. Earlier submarines (before World War II) used vertical folding planes perpendicular to their surface. American submariners called this warehouse "stow" for aircraft and "slant" for their control movement.

Was the first to develop an aircraft capable of depth control without the introduction of a stick. The transoms and rudder were similar to those of a normal ship under the stern. The depth control planes were mounted on the beam, so that they operated vertically, without a lever, to enter the usual pitch.

Fairwater planes do not tilt the boat up or down; Cause the ship to rise or sink while driving on a level plane.

A submarine under the polar ice must use sailplanes to break through the ice on its way to the surface. From the Sturgeon class, they are designed to point vertically upwards rather than being clipped or folded.

The new boats, starting with the third-flight Los Angeles-class submarines (or 688is), have done away with gliders and are instead powered by bow craft.

Maintaining depth in a submarine is a delicate task. The hiker was given a visible depth gauge, usually a circular Bourdon gauge. An additional pressure gauge for shallow depths, a transparent vertical tube, will also be provided for accurate maintenance of periscopic depth. With the development of active sonars, depth control has become even more difficult. Instead of maintaining a simple depth, the pilot must now keep the bottom of the ship in the thermocline to hide from the sonar. For this purpose, the position of the rudder can also be indicated by external water thermometers and salinometers.

The first submarines had separate controls for each pair of planes, bow and stern. With the helmsman, this required three ratings in an already crowded control room. By the 1960s, combined control was introduced. They included all aircraft on a single aircraft-style control wheel.

In automotive terms, dive planes (which physically resemble underwater diving planes) are aerodynamic devices mounted on vehicles directly in front of the front wheels. Most commonly found on racing cars such as the Le Mans Prototype Series, they are used to create additional downforce and airflow to help balance the car. The 2012 Mercedes-Bz C63 AMG Black Series is one of the first road-going vehicles to feature these devices. A flying submarine, underwater vehicle or air submarine is a combination of a seaplane and a submarine. He must be able to fly and travel underwater. It is also planned to take off from the water surface.

Since the design requirements of a submarine are practically the opposite of those of an aircraft, the performance expected from such a design is usually quite moderate.

As early as 1920, the British trade magazine Flying reported discussions between the First Sea Lord and other military leaders and a major aircraft manufacturer about a flying submarine (or underwater seaplane). The all-metal ship, the hypothetical design of which is illustrated in the article, was to be a twin-propeller aircraft with retractable wings and a hermetically sealed fuselage. However, it seems that no further development of the project took place.

In 1934, Soviet engineer Boris Ushakov proposed a design for a submarine that would scout ships and dive into the water to ambush them. The design had three engines, a conning tower, a periscope and could fire torpedoes (of which it carried two). It would sink by flooding its hull and use electricity to propel itself underwater. The craft took off and landed like a normal seaplane. However, the Soviets found the craft too heavy to use.

In 1961, Donald Reed designed and built the Reid Flying Submarine 1 (RFS-1), a single-seat (32.83 ft or 10 m long) aircraft capable of flying and moving underwater.

). A 65 hp (48 kW) pylon-mounted engine provided flight propulsion; A 1 HP electric motor in the tail is involved in underwater propulsion. The pilot was using scuba gear to breathe underwater. The first full-cycle flight [underwater at a depth of 6.5 feet (2 m), in the air at a height of 33 feet (10 m)] was demonstrated on June 9, 1964.

Reid, his plane and his son (a test pilot) appeared on the US show "I've Got A Secret" on March 15, 1965.

In the mid-1960s, the Navy awarded Convair a contract to design a submarine. The project - called the Convair Submarine Seaplane - reached the detailed design and model stage, but was canceled by Congress.

In 2008, the US Defense Advanced Research Projects Agency announced that it was preparing to award contracts for the submarine.

The “x Factor” In Columbia Class Submarine Design

To propel DARPA's spacecraft underwater, it is believed that high-energy batteries could be used to power underwater engines. However, one problem identified with this proposal was that the batteries required to meet DARPA's specifications would make the vehicle too heavy to fly. A proposed solution was to use a t-metre high snorkel to feed air into a more conventional petrol turbine engine, although this limited how far the submersible could go.

Another project involved the Lockheed Martin Cormorant unmanned aerial vehicle. It would be launched from submarines, replacing the launch tubes of several cruise missiles. To reduce the risk of detection during launch, the drone would first be released from the submarine, which would take off. The aircraft would use compressed gas to propel it to the surface and use rocket engines before using a jet engine in the air. To return to the submarine, the drone would land on the surface of the ocean using a parachute and be retrieved by a swimming drone. Cormorant was canceled in 2008 due to budget cuts.

Some proposals for underwater vehicles included the use of jet engines in the dual role of both propelling the vehicle into the air using conventional combustion and providing underwater thrust by turning with an electric motor; Some researchers have suggested the use of a turboshaft engine in air and underwater conditions to achieve the best efficiency and performance. To prevent premature burying of saltwater engines when the ship is not submerged, the engines can be mounted on the back surface and stern of the ship. One problem, however, is that jet engines operate at several hundreds of degrees Wh in the air, they cannot immediately go underwater, because exposure to seawater would expose them to extreme temperature changes that would damage them and force the aircraft to wait several hours on the surface. cooling their engines prior to submersion, so any such configuration would require a new cooling system for a faster transition.
