It employs distributed propulsion using twelve turboshaft engines,” reads the DARPA release. “The General Atomics team has selected a twin-hull, mid-wing design to optimize on-water stability and seakeeping. Airplanes experiencing ground effect use less energy to move through the air at high speeds and in turn take less energy to fly.īoth companies have taken different approaches to their designs. Fixed-wing aircraft flying close to the behave like they’re riding on a cushion of air between the ground. In the first phase of the contract, the two teams will develop an aircraft that will carry two Marine Corps Amphibious Combat Vehicles or six 20-foot-long cargo containers at just above the wave tops using the physics of the ground effect. 27, with options that could grow the contract to $27 million. Aurora, a Boeing subsidiary, was awarded $5.7 million on Jan. 27, was for $5.7 million and could grow to more than $25 million if all options are exercised. Aurora’s contract, which DARPA awarded Jan. The contract could include options brining the value to $29 million. General Atomics was awarded $8 million cost-plus-fixed-fee contract award in support of DARPA’s Liberty Lifter program in November for the work, the company announced Wednesday. “Liberty Lifter will use low-cost manufacturing akin to ship fabrication in building a highly innovative seaplane capable of meeting DoD heavy lift requirements that operates with runway and port independence.” Goals include takeoff and land in Sea State 4, sustained on-water operation up to Sea State 5, and extended flight close to the water in ground effect with the capability to fly out of ground effect at altitudes up to 10,000 feet above sea level,” reads a statement from DARPA.Īrtist’s concept of Aurora Flight Sciences bid for DARPA’s Liberty Lifter Program “The planned Liberty Lifter demonstrator will be a large flying boat similar in size and capacity to the C-17 Globemaster III transport aircraft. General Atomics, working with Maritime Applied Physics Corporation, and Aurora Flight Sciences, working with Gibbs & Cox and ReconCraft, each won contracts to start design and development work for a prototype Liberty Lifter cargo aircraft, according to the DARPA announcement. The Pentagon’s emerging technologies research arm awarded two aviation companies contracts to develop seaplanes that would fly less than 100 feet off the ground and carry 90 tons of cargo more than 6,500 nautical miles, the Department of Defense announced Wednesday. This post has been updated with additional contract information. Implementing some of the material knowledge in building the hovercraft construction.Artist concept of General Atomics bid for DARPA’s Liberty Lifter Program.Implementing some method of manufacturing in building the hovercraft construction.Apply knowledge and engineering principles gained during our study.increase awareness of alternative method of transportation.Design and build a hovercraft that can float in different land types and can withstand the Kingdom harsh landscape.The significant of the hovercraft comes in situations like flooded areas like what happened in al-Khobar city a few weeks ago. For commercial operation also hovercraft can play a distinct role in guiding the ships to the shore safely and efficiently rather than using small boats which can cost a lot in maintenance. The project is helpful and necessary many cases such as military and security in which hovercraft are excellent for off beach protection and rescue. The mechanical part of our project is the engine and control system which help in maneuvering and monitoring the direction of the hovercraft. Underneath the wood, the skirt or cushion takes place, and it functions to create a change in pressure bycatch the air in one area to create the required difference in pressure between inside and outside of the skirt. The concept of the hovercraft is simple, starts with a particular kind of wood that has the property in carrying loads and has some gaps to help wood floats above any land. In this project, we intended to build and design our hovercraft which could work in many circumstances as much as the car regarding any land. Hovercraft sometimes called Air Cushion Vehicle due to its ability to move by cushion or skirt filled with air and cause the board to hover above the ground, and by the thrust engine it runs forward and fills up the cushion. A Hovercraft is a vehicle that floats above any lands such as ice, sand, grass, and water.
