The folks at Advanced Aerodynamic Vessels splashed their experimental prototype A2V
A2V is a new generation of transportation vessels using aerodynamics to improve energy efficiency.
During the last two years, the A2V team of naval architects and CFD specialists developed
a revolutionary shape able to safely transfer ships weight from water to air.
The required propulsive power depends mostly on the weight carried by the water. Reducing this weight is the key to greater efficiency.
A2V coordinates sea trials on a fully instrumented prototype to validate the numerical simulations carried out for the last two years.
Speed, fuel efficiency, manoeuvrability, seakeeping and many other variables will be accurately monitored to optimize our prediction tools.
Le Marin's Article loosely translated:
The company Advanced Aerodynamic Vessels (A2V) presented this Wednesday, March 25th the prototype of a fast ship energy efficient. This prototype measuring 10.50 meters. Built in Hervé site in La Rochelle, this machine is a catamaran equipped with two outboard motors with 200 hp which should allow it to reach and exceed 40 knots.
Designers expect a version of 25 meters, for example in a version that can carry 60 passengers ferryboat, it can reach 60 knots.
The interest of prototype, through the measurement campaign will be carried out during sea trials, will "validate the expected energy performance and calibrate numerical models developed by the company to develop this new generation of ships ".
"We are preparing the prototype for two years, says Lionel Huetz, Research and Development at A2V. This boat polyester PVC foam sandwich has been designed to generate aerodynamic lift by its speed. It is able to go very fast by spending little fuel. "

"We are preparing the prototype for two years, says Lionel Huetz, Research and Development at A2V. This boat polyester PVC foam sandwich has been designed to generate aerodynamic lift by its speed. It is able to go very fast by spending little fuel. "
The company's project is to build work boats 10 to 30 meters with these characteristics: boat transportation, surveillance, crewboat, boat taxi passenger. The prototype, packed with sensors, will start sea trials in a month to validate weeks calculation and computer simulation which have led to this futuristic catamaran forms.
The engineers and naval architects of Advanced Aerodynamic Vessels "devised a form that is based on the air when the boat picks up speed. In other words, it is no longer fight against the air to move forward, but to use it to lighten and significantly reduce resistance to the advancement of the ship. The idea is simple, but its development has required thousands of hours of computer calculation. "
The Central School of Nantes and the naval architects, including Marc Lombard in La Rochelle, participated in the development of this unit. This is the result of a very thorough research work on stability, aerodynamics and hydrodynamics. The tests will tell if the theory pass the test of practice.
The company states that "the construction in record time was a challenge all the more daring as the boat has complex shapes. A small team, versatile and very creative construction techniques allowed the project to return to the limited budget allocated to the prototype. "
