Most small aircraft have traditionally used petrol/piston engines similar to those in cars. Yet, these can be suboptimal for aviation use. A better alternative is the compression-ignition design, also ...

MIT researchers serendipitously developed a novel "toroidal" propeller design that is significantly quieter and produces more thrust than conventional drone propellers. The unique closed-loop shape of ...

Quantum computing is moving beyond theory, with BQP using quantum optimization to redesign drone propellers in ways conventional computing cannot. BQP and Modovolo are using quantum-designed ...

Years after the space race, propeller design remained a sea-trial-and-error endeavor: haul, tweak the props, relaunch, sea-trial, repeat. Finally, the U.S. Navy paid ...

Wärtsilä introduced the FPP Opti Design, a new fixed pitch propeller (FPP) design concept. According to Wärtsilä, the new design offers fuel savings of up to 4 percent and highly reliable full scale ...

EDWARDS AIR FORCE BASE, Calif., Nov. 8 (UPI) -- Hamilton Sundstrand NP 2000 propellers are being tested by U.S. Air Force engineers in California on a C-130H3 aircraft. The new eight-bladed composite ...

Hydrocomp’s newest release of PropCad incorporates 3 years of enhancements. Propellers are surprisingly complex devices, especially considering most are a solid piece of metal with no moving parts.

Combination of carbon, glass and epoxy resin produces a strong replacement for nickel/aluminum/bronze metal, the current propeller standard. Damage-tolerant reinforcing fabric strengthens highly ...

A digitizer captured the dimensions of one of the propeller blades on the fishing vessel named Harmony. A laser tracker helped measure a 25-year-old propeller in just a few hours as a means of ...
