The set-up for motor/propeller testing has to meet the twin conditions of speed and accuracy. The engineering requirement was to measure power dissipation in the drivetrain given known power input and known rotor speed (rpm) measurement.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

The set-up for motor/propeller testing has to meet the twin conditions of speed and accuracy. The engineering requirement was to measure power dissipation in the drivetrain given known power input and known rotor speed (rpm) measurement. The challenge for the Atmos' engineers was to achieve highly accurate measurement results while keeping the test time for each motor/propeller combination as short as possible.

Atmos used Yokogawa's WT1800E power analyser to take simultaneous current and voltage measurements at the motor’s power supply, at the motor drive circuit, and at the motor. These measurements were used to calculate power dissipation in the motor drive and the motor.

The Marlyn design has exceeded our expectations in terms of reliability

"The most important question with measurement equipment is, can you trust the results it produces? I did not have to worry about the WT1800E on this score – I had total confidence in the values displayed on screen. I know that the WT1800E was telling me the actual power dissipated" says Dirk Docter, Technical Director & Founding Partner of Atmos.

"The Marlyn design has exceeded our expectations in terms of reliability. That’s not just in normal operation – because of the results from our power dissipation testing, we know that we can produce more thrust without risk of the drive overheating. We have a safety margin over and above what’s required in normal operation. That’s very important for us, because our name is on the aircraft, and the Atmos brand stands for reliability and performance."
