The Presence Of Looprop JAXA And ACSL Successfully Reduces Noise In Drones

JAKARTA In addition to focusing on exploration missions using lander robots, the Japan Space Exploration Agency (JAXA) is also focusing on developing unmanned drones or aircraft.

In March this year, JAXA collaborated with ACSL, a developer drone company, to create a propeller with the name Looprop. The developer development process was summarized and released in JAXA's latest article.

Initially, ACSL's drone SOTEN used a propeller with the basic shape used by drones in general. However, this propeller creates noise that makes the surrounding environment uncomfortable.

With this voice problem, JAXA and ACSL are working to develop new propellers capable of producing minimal noise. In this process, Looprop comes with a size similar to the number eight and has a large arch.

The key to achieving a low level of noise is the curvature of the propellers. This allows the propellers to interact gently with the surrounding air during rotation, resulting in a noise reduction effect," said JAXA employee, Eiji Shima.

When it was first developed, Shima and her team simulated the geometry parameters in the form of the Looprop prototype. However, this research did not go well because its thin shape and light shape actually made Looprop weak.

The second study continued to modify its thickness while maintaining the weight and previous design. Luckily, this second study went perfectly so that Looprop was finally launched.

JAXA and ACSL use materials that are common in the development of the Looprop model. Therefore, JAXA claims that Looprop is not only made for drones, but also for other tools that require a propeller.
