The U.S. Army has partnered with Rensselaer Polytechnic Institute (RPI) in New York to develop a “trajectory planner” element to help improve vertical takeoff-and-landing maneuverability for quadrotor drones

Researchers integrated the tail-sitter onto a Common Research Configuration quadrotor biplane to test the element's ability to affect rotor movement and wing aerodynamics particularly in dense locations and urban areas, the Army Research Laboratory said Tuesday.

Jean-Paul Reddinger, an aerospace engineer at ARL’s Vehicle Technology Directorate, said the trajectory planner’s capacity to transition the platform between hover and forward-flight could help the Army in applications such as aerial resupply and intelligence, surveillance and reconnaissance.

“The goal of this work was to use a model-based trajectory planner that could capture the quadrotor’s dynamic characteristics sufficiently while executing quickly enough to provide trajectories in-flight,” he said. 

“The direction we’re trying to take this in is to incorporate obstacles and additional kinds of constraints on its maneuverability.”

RPI and the Army plan to conduct further simulation trials for the tail-sitter ahead of hardware integration activities and flight tests.

Gen. Mark Milley: Universal Data Standards Key to Joint Warfighting

Gen. Mark Milley, chairman of the Joint Chiefs of Staff, has said that he plans to implement foundational data standards and pitch his concept for joint warfighting that leverages networked forces. A joint system that builds on common standards across the services branches must be in place by the end of the year, he said.
