Airbus to Pursue US Army Helo Program With X3-Based Platform

Airbus Helicopters CEO Bruno Even said the company has proposed an aircraft design based on its X3 technology, which recorded a speed of more than 290 miles per hour before it was retired in 2014.

Even said Airbus is enhancing the technology to meet future military requirements for high-speed helicopters.

IMOHO, it can only be that someone at Airbus misstook FARA for the Spanish word ... ¡caray!​​*

From the Osprey to the CH-53K: Progress in Building a Maintainable Aircraft

Aren’t you with the logs demo shaping domain knowledge rather than manuals to launch the K fleet experience?

Lambert: That is correct.

“We are focused on having the Marines working with the airplane get familiar and comfortable with the maintenance approach and indeed, to shape that approach.

“In Osprey interviews which you published from a decade ago, one of the challenges highlighted was the lack of knowledge, the lack of being comfortable with the airplane which led to a high amount of premature removal of parts for unknown failures.

“We are focused on training the Marines to make good sound judgment calls when troubleshooting and performing maintenance.”

An interesting piece worth reading

Brazil’s navy ordered three Airbus H135 light twin-engine helicopters.


The helicopters will be operated by the 1st General Purpose Helicopter Squadron and will be used for missions such as special operations, transport of troops and freight, naval inspection, search and rescue and medical evacuation, says Airbus Helicopters. The aircraft are replacements for the Brazilian navy’s twin-engine, light utility Eurocopter AS355 Écureuil helicopter.

Airbus Helicopters launches 5-bladed H145 upgrade

The blades incorporate the latest airfoil design to produce more thrust than previous blades at the same power. While five blades have more drag than four blades in a rotor, Humpert said improvements to the aerodynamics of the rotor cuff of the blade had actually allowed the new H145’s blades to provide more lift. “This is the aerodynamic evolution which is technically behind it,” he said. The new H145’s blades fix directly onto the main rotor mast, meaning fewer parts and simplified maintenance. Airbus Helicopters Photo
The new main rotor system has been simplified with no main rotor head — so the blades are attached directly to the rotor mast. This means fewer parts, resulting in the lower weight and simplified maintenance.

The blades have been designed for simplicity and thrust efficiency, said Humpert, and provide “some different characteristics” during flight. He said these included an increase in comfort level (with reduced vibration), while maintaining the same levels of noise and efficiency as the existing H145.

Is it just me or S97 design is better?, more practical and what not

The advantage of the X-3 layout is that it can scale up nicely.

The S-97 might run into problems of providing sufficient thrust through one propellor, and length of driveshaft.

The design is a record breaker working prototype. Not the proposed one.
