Laminar-Flow Flight Campaign Validates Aerodynamic Efficiency

Otto Aerospace has completed a flight-test campaign for an unmanned drone aircraft developed around its laminar-flow technology, validating the predicted aerodynamic efficiency of the aircraft’s design in flight.

The campaign was conducted from Spaceport America within the White Sands Missile Range airspace in New Mexico. Otto’s laminar-flow technology is designed to reduce aerodynamic drag by maintaining smooth, uninterrupted airflow over an aircraft’s surfaces.

The drone received partial funding under a 24-month contract with the Defense Advanced Research Projects Agency (DARPA) and the Operational Energy Capability Improvement Fund (OECIF) supporting research for DARPA’s Energy Web Aircraft (EWA) program. Focused on power-beaming and distributed energy web exploration, the EWA program sought to enable laser-based power transfer across long distances using airborne relays capable of beaming energy to aircraft.

According to Otto Aerospace, the flight-test campaign announced today was independently funded by the company and conducted outside the scope of the DARPA and OECIF contract.

Otto’s role in the program focused on developing a highly laminar-flow efficient airframe. The effort leveraged the company’s aerodynamic expertise to design and flight-test an unmanned vehicle intended to inform future energy-relay systems and fuel-efficient, long-endurance platforms.

Flight operations were conducted in partnership with Swift Engineering, which managed vehicle preparation and coordinated range and telemetry support. Swift Engineering’s experience with high-altitude UAVs and operational presence at Spaceport America supported multiple sorties conducted over White Sands Missile Range airspace.

Scott Drennan, President and CEO of Otto Aerospace, commented, “This aircraft proved what we’ve modeled for years, that high-efficiency laminar-flow aerodynamics can deliver extraordinary endurance and performance. We’re proud that Otto’s expertise helped advance DARPA’s research objectives and equally proud of our team for executing a flawless flight campaign that pushes aerodynamic science forward.”

Conceived under DARPA’s Energy Web Aircraft effort, the demonstrator serves as a broader validation platform for Otto Aerospace’s laminar-flow research, providing data applicable to future energy-relay UAV concepts as well as the company’s commercial and defense programs.

Hamed Khalkhali, President of Swift Engineering, stated, “Swift is proud to partner with Otto on this breakthrough. The performance demonstrated in flight confirms the promise of laminar-flow aerodynamics to redefine long-endurance efficiency for unmanned systems across defense and commercial applications.”

“The data collected in this test opens new possibilities for energy-efficient aviation,” said Drennan. “From business jets to long-endurance UAVs, we’re showing how laminar flow can change what’s possible in flight.”
