California-based Elroy Air has pulled off a key milestone with its Chaparral cargo drone, successfully shifting from vertical takeoff to forward, wingborne flight in a series of trials.
The hybrid-electric aircraft hit speeds of 70 miles (112.7 kilometers) per hour on each flight, lifting off vertically, cruising on its wings, and completing its journey with a vertical landing.
According to the company, transitioning to wingborne flight lets the aircraft use less power, boosting overall efficiency and potentially extending range and making routine cargo missions more practical.
“Our team has made a remarkable technical achievement,” said Elroy Air Chief Executive Officer Andrew Clare.
“This is one of the most technically complex phases of VTOL flight, requiring careful autonomous orchestration between all control systems and a detailed understanding of the specific aerodynamics and structural dynamics of the aircraft.”
Elroy Air is set to conduct a 25-mile (40-kilometer) demonstration later this month. It also plans to develop dual-site cargo delivery capability by the end of the year.
A Closer Look
The Chaparral is designed to carry over 300 pounds (136 kilograms) of payload across distances of 300 miles (482.8 kilometers).
Equipped with a hybrid engine, it can refuel quickly for extended endurance and longer range cargo delivery.
Elroy Air said the design emphasizes efficiency and safety, keeping personnel out of danger while cutting costs compared to piloted aircraft.
According to Clare, the Chaparral is engineered with “mechanical simplicity,” enabling fewer moving parts for greater reliability and lower maintenance demands.
“Chaparral is designed to meet the demands of being operational and sustainable in the field,” he stated.
“These recent flights have shown that Chaparral can seamlessly transition back and forth from vertical hover to wingborne flight, setting the technical foundation for full mission capability and productization.”
