Beartrap (helicopter Device)
A helicopter hauldown and rapid securing device (HHRSD) or beartrap enables the landing and handling of helicopters and unmanned aerial vehicles (UAVs) aboard small ships in poor weather. The beartrap was developed by the Royal Canadian Navy (RCN) in the 1950s and 1960s, and entered service in 1967. It was quickly adopted by other navies and remains in use. History By the mid-1950s, many navies were introducing ship-based helicopters to perform a variety of functions, from logistical support to anti-submarine warfare. However, a common difficulty was landing and handling the aircraft, particularly larger ones, on a flight deck in motion. These conditions were particularly acute in poor weather and on smaller ships. Fitting ships with roll-dampening fins provided insufficient mitigation. At the time, aircraft carriers were considered to be the only practical platforms for operating helicopters at sea. The RCN began investigating the problem in the 1950s. Early trials used the fr ...

Sikorsky CH-124 Sea King
The Sikorsky CH-124 Sea King (formerly CHSS-2) is a twin-engined anti-submarine warfare (ASW) helicopter designed for shipboard use by Canadian naval forces, based on the US Navy's SH-3 Sea King. Most CH-124s were assembled in Quebec by United Aircraft of Canada. The CH-124 served with the Royal Canadian Navy (RCN) and Canadian Armed Forces from 1963 to 2018. Design and development The advent of nuclear-powered submarines in the late 1950s let to the RCN assessing this new threat. While noisier than older submarines and thus detectable at longer ranges, nuclear submarines could also reach while submerged, faster than the RCN's new destroyer escort's top speed of . There were doubts that destroyers could effectively pursue and destroy such fast vessels, even when operating in pairs. During a 25 February 1959 Naval Board meeting, it was decided to counter the threat by operating helicopters from destroyers.Soward 1995, pp.169–171. The RCN examined the feasibility of operatin ...

Aircraft Ship Integrated Secure And Traverse
The Aircraft Ship Integrated Secure and Traverse (ASIST) system is a shipboard helicopter landing system developed by Canadian company Indal Technologies (now part of US conglomerate Curtiss-Wright). ASIST completed sea trials by July 31, 1992, and production units are in operation with the Chilean Navy, Republic of Singapore Navy, Turkish Navy and United States Navy The United States Navy (USN) is the naval warfare, maritime military branch, service branch of the United States Department of Defense. It is the world's most powerful navy with the largest Displacement (ship), displacement, at 4.5 millio .... Mode of Operation The ASIST system employs a sophisticated electro-optic tracking system which detects a laser beacon-equipped helicopter. The system tracks the helicopter and provide real time helicopter position simultaneously via visual cues to the pilot. A computer-controlled rapid securing device will also be driven by the position data to track the helicopte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulics
Hydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of Power (physics), power by the use of pressure, pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and they cover concepts such as pipe Volumetric flow rate, flow, dam design, fluidics, and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. ''Free surface hydraulics'' is the branch of hydraulics dealing with free surface flow, such as occurring in rivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter Deck
A helicopter deck (or helo deck) is a helicopter pad on the deck of a ship, usually located on the stern and always clear of obstacles that would prove hazardous to a helicopter landing. In the United States Navy, it is commonly and properly referred to as the flight deck. In the UK's Fleet Air Arm, ''landing on'' is usually achieved by first lining up on the port quarter parallel to the ship's heading, then once the deck motion is deemed to be acceptable the pilot sidesteps the aircraft laterally using a white painted line (the bum line) as a reference. Shipboard landing for some helicopters is assisted though use of a haul-down device that involves attachment of a cable to a probe on the bottom of the aircraft prior to landing. Tension is maintained on the cable as the helicopter descends, assisting the pilot with accurate positioning of the aircraft on the deck; once on deck locking beams close on the probe, locking the aircraft to the flight deck. This device was pioneered b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Maritime Self-Defense Force
The , abbreviated , also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel. History Origin Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as the battleship , were taken by the Allied Powers as reparations. The remaining ships were used for repatriation of the Japanese soldiers from abroad and also for minesweeping in the area around Japan, initially under the control of the ''Second Bureau of the Demobilization Ministry''. The minesweeping fleet was eventually transferred to the newly formed Maritime Safety Agency, which helped maintain the resources and expertise of the navy. Japan's 1947 Const ...

Sikorsky CH-148 Cyclone
The Sikorsky CH-148 Cyclone is a twin-engine, multi-role shipborne helicopter developed by the Sikorsky Aircraft Corporation for the Canadian Armed Forces. A military variant of the Sikorsky S-92, the CH-148 is designed for shipboard operations and replaced the CH-124 Sea King, which was in Canadian Armed Forces operation from 1963 to 2018. The Cyclone entered operational service with the Royal Canadian Air Force (RCAF) in 2018 and now conducts anti-submarine warfare (ASW), surveillance, and search and rescue missions from Royal Canadian Navy frigates. The helicopter also performs utility and transport roles in support of national and international security efforts. In 2004, Canada awarded Sikorsky Aircraft a contract for 28 CH-148s with deliveries originally planned to start in 2009.
