Following years of devoted work with unmanned aerial automobiles (UAVs), NPS and Naval Analysis Laboratory (NRL) companions have efficiently concluded the final word check of a nine-year continuum of analysis and improvement in one of many world’s most difficult environments: the Arctic Circle.
The collaborative staff built-in NPS’ personal cutting-edge flight-path planning software program referred to as POTION (Path Optimization) with the Vanilla UAV, developed and operated by Platform Aerospace. This initiative pushed the boundaries of their analysis, subjecting the Vanilla-POTION mixture to rigorous testing within the daunting North Slope of Alaska, making the perfect of a slender climate window.
Remarkably, the outcomes of the Arctic flight in September surpassed all expectations, in addition to quite a few information set by Vanilla in earlier missions. This achievement underscores the distinctive capabilities of the Vanilla-POTION mixture and represents a milestone in advancing UAV expertise for naval operations throughout the scope of the long-term partnership.

Main NPS efforts on what he phrases “energy-aware aerial flight” is NPS Affiliate Professor of Mechanical and Aerospace Engineering (MAE) Dr. Vladimir Dobrokhodov, who started at NPS as a postdoctoral fellow in 2001.
“A glider’s effectivity is quantified by its considered power utilization, a stark distinction to the fight effectivity metrics utilized to fighter plane. Much like transport planes, gliders goal to traverse huge distances with minimal gasoline consumption,” defined Dobrokhodov. “Over a meticulous nine-year collaboration between NPS and NRL, modern approaches have been developed to optimize effectivity of lengthy endurance plane.”
Again in 2014, Dobrokhodov labored alongside NRL’s Dr. Dan Edwards and Dr. Richard Stroman to discover energy-aware flight analysis with a novel hybrid UAV known as Hybrid Tiger that built-in hydrogen gasoline cell, photo voltaic and atmospheric wind energy-harvesting applied sciences. The undertaking spanned three years.
Central to the undertaking’s achievements was the event of optimum trajectory planning software program emulating the energy-conserving flight patterns of migrating birds navigating atmospheric wind rivers.
Within the realm of energy-efficient flight, characterised by low airspeeds and altitudes, susceptibility to the antagonistic results of sturdy winds and icing is amplified, making flight-path planning extraordinarily difficult for human operators. Mathematical optimization of routing turns into very important, necessitating a posh software program answer that allows the plane to skillfully navigate by way of numerous and probably hazardous climate circumstances.
Shut collaboration with MAE professors Mark Karpenko and Kevin Jones, researchers who’ve spent years within the space of flight effectivity and optimum management engineering, helped to advance the power optimum strategy to what’s now POTION. The staff developed the propulsion effectivity mannequin of an plane to mannequin the Vanilla UAV’s gasoline consumption and used machine studying to combine that mannequin into the algorithm for route optimization.
“Utilizing neural networks to symbolize and rapidly execute an in any other case sophisticated power mannequin was a key enabler for optimizing Vanilla’s flight path,” Karpenko stated.
