Angled decks that greatly improved the ability to safely abort a missed landing.Optical and electronic landing direction systems to replace human-to-human methods.Highly energetic catapults, first hydraulic, then steam, and now possibly linear electromagnetic motor.The major systems, many originated in Britain and refined by the United States, were: Aircraft carriers further evolved, a process that has not stopped, when they could operate even bigger and more powerful aircraft.

They had the greatest impact on the design of the ship itself, but the aircraft were affected. Several developments had to come together to make the modern military aircraft carrier. While early jet engines offered more speed and power than propeller engines, the jets of the time also were slow to accelerate for takeoff, or to abort a potentially catastrophic landing. Mission requirements, such as carrying airborne radar or heavy nuclear weapons, required more total power. They did use arresting wires to stop the aircraft on landing, but the method had many limitations. During the war, propeller-driven aircraft essentially made a short takeoff relying only on their own engine power. Contact us for more information on how we can develop a specialized phantom for your application.The various systems and procedures involved in Catapult Assisted Take Off But Arrested Recovery (CATOBAR) were the keys, following the Second World War, to operating large, high-performance aircraft from carriers. To support this work we have developed expertise in image segmentation (automated extraction of specific organs from three-dimensional CT images), rapid prototyping, and novel methods of material fabrication and molding.

Head phantoms capable of generating electroencephalograph (EEG) signals.

Abdominal phantoms that simulate colon motion as subjects change body orientation during CT screening for colorectal cancer.

Head phantoms that simulate the response of the head, skull, and inner ear to sound.

These models and phantoms can contain multiple simulated organs with realistic mechanical and electrical properties.Įxamples of these anatomic phantoms include: We have developed complex anatomic phantoms that enable our clients to simulate physiologic processes in the laboratory or field. We often construct anatomic models to mimic the response of the actual human body in a highly repeatable manner that can be carefully studied. Many of Creare’s biomedical projects include study of the behavior of the human body under conditions ranging from simply rolling over to repeated vibration exposure. There has not been a single failure of any kind with these units. Navy fleet, and have also been successfully used on the French Navy’s carrier. Since 2007, these systems have been used successfully all over the world on every active aircraft carrier in the U.S. These systems have reduced the time required to make the gap width measurements by 94% and have simplified logistics by eliminating the need for onboard heavy support equipment. After developing and field testing several prototype versions of the instrument, Creare produced and delivered eight complete systems to the Navy. Creare’s entirely wireless and fully autonomous instrument obtains data on the health and status of the catapult cylinders to aid in condition-based maintenance.

carriers, and obtaining accurate gap width measurements for an aircraft carrier fleet that spans the globe has been a challenge for the Navy. Aircraft carrier catapult instrument robotically measures the critical gap width of steam-powered catapult launch cylindersĬreare designed and manufactured a specialized robotic instrument for measuring the gap width of steam-powered catapult launch cylinders onboard aircraft carriers, a critical dimension that must be monitored to ensure reliable aircraft launch.
