Ultra-strong, ultra-light

Innovative drive technology from Faulhaber is playing a key role in the Flywhale, an amphibious aircraft made from super-light composite fibre materials. Targeted at aviators with a passion for water, as well as coast guard and rescue services, Flywhale is just at home on water as it is on land or in the air.

Developed by Flywhale Aircraft, Germany’s only manufacturer of ultra-light sea planes, the Flywhale is capable of speeds up to 200km/hr. The company currently manufactures eight aircraft per year, and is aiming to achieve up to 20 per year.

“The latest technology is used for the construction of our Flywhales, and we use the best materials,” says company co-founder Helmut Rind. Components from Faulhaber play an important part in lowering and raising the landing gear. One drive for the main landing gear and one drive for the nose gear are realised using Fauhaber products, available in the UK from EMS.

The nose gear is moved by a spindle mechanism. The drive solution from Faulhaber ensures that the required rotation of the lead screw takes place. A drive unit is used which consists of a Faulhaber graphite-commutated series 3257...CR DC motor, including an

IE3-1024 Encoder and a type 32/3S planetary gearhead. A type MCDC 3006 S RS controller completes the intelligent system.

“The end positions for the status of the raised and lowered landing gear are determined by the encoder and controller, and are displayed in the cockpit as a signal using a blue and green control LED”, explains Michael Schütte, area sales manager at Faulhaber. “This means that we were almost able to dispense with an additional sensor system for end position detection altogether.”

The nose gear is also equipped with a spring element which ensures that outstanding suspension comfort is provided. The two main landing gears are raised and lowered using a worm gear drive. The same Faulhaber drive as the one used for the nose gear is used at both sides.

A screw which moves the landing gear via a gear segment is driven by the Faulhaber gearhead type 32/3S via the gearbox output shaft. Just as with the nose gear, the end positions are detected accordingly via the encoder and the controller and displayed in the cockpit.

“The drives must provide a high level of drive power for a short time and be as light as possible,” elaborates Schütte. “In addition, the landing gear movement must be able to take place both in the water and in the air.” The system therefore needed to be extremely reliable. Because of their light weight, high power density and compact size, the Faulhaber components proved to be just the job for this.

As far as Rind is concerned, it is not only technical reliability of the motors but also Faulhaber’s professional service that set the company apart. “We are delighted to colla-borate with Faulhaber, he emphasises. “The thing that Faulhaber and Flywhale have in common is that we are only satisfied with the best result.”
