Anybody who depends on propellers for his or her work or passion has cause to have a good time the latest collaboration between UBIQ Aerospace and Mejzlik Propellers, introduced on March 30, 2021. The 2 corporations, primarily based in Norway and Czechia respectively, are collaborating to develop a system that may forestall ice accretion on plane and drone propellers. “The target is to supply an ice protected propeller for sustained flight in atmospheric icing situations”, says Kim Lynge Sørensen, founder and CEO of UBIQ Aerospace.
UBIQ Aerospace makes a speciality of ice safety methods for plane and leans on a few years of analysis and expertise to tell their options. Their D•ICE expertise is the one autonomous icing safety resolution obtainable for unmanned plane. The system makes use of each anti-icing and de-icing expertise to supply an answer that optimizes ice safety and effectivity to lengthen drone endurance.

The collaboration goals to develop a propeller that comes with UBIQ Aerospace’s proprietary applied sciences into Mejzlik’s famend propellers.
Mejzlik Propellers has been within the manufacturing enterprise for many years, with merchandise for each electrical and combustion engines. Over time Mejzlik has stepped out of their consolation zone quite a few occasions, creating propellers for a variety of makes use of together with planes, helicopters, wind generators, and heavy-lift drones. With in depth expertise in custom-designed propellers, Mejzlik is the perfect associate for this growth undertaking.

The 2 corporations hope to work collectively to resolve the issue of in-flight propeller icing, which happens when supercooled water droplets freeze to the forefront of the propeller. This could result in decreased efficiency and even lack of the plane if the icing happens at a excessive altitude or past visible line of sight (BVLOS).
A key a part of their R&D course of is figuring out how and when icing takes a toll on the propeller. A small quantity of ice accumulation may not doom the plane, however efficiency will decline increasingly with the build-up. Preliminary outcomes collected utilizing an icing wind tunnel and the Collection 1780 check stand demonstrated that icing can cut back propeller efficiency by as much as 40% inside the first minute.

These preliminary outcomes emphasize the necessity for high-performance propellers that may keep away from ice build-up throughout sustained flights, a vital attribute for business drones concerned in high-stakes operations. This partnership guarantees to carry new and efficient options to the business to deal with this essential situation.
