(Purdue Research Foundation photo by Oren Darling) Startup company Tri-D Dynamics LLC, a startup with ties to Purdue University, plans to use 3D printers as well as other additive manufacturing processes to make future rocket engines that show promise in being faster and less expensive to produce than traditional methods. The 3D printer would create small rocket engines for satellites.

Simulation Software Improves Pilot Training

Simulation of a helicopter landing on a ship. (Chair of Helicopter Technology/TUM) Providing pilots with the best possible preparation for extreme situations is the goal of new simulation software. The program that combines flow mechanics and flight dynamics in real time. The numerical model is extremely flexible and does not depend on stored flow data. External conditions such as topography, global wind speeds, and aircraft type are input. During the simulation, the algorithms use that data to continuously compute the interacting flow field at the virtual aircraft’s current location.

High-Speed, Autonomous Surface Patrol Capability Demonstrated

A successful demonstration by Johns Hopkins APL and the Surface Targets Branch of the Naval Air Warfare Center Weapons Division involved six surface target boats operating together at high speeds, using hardware and software that APL developed and integrated with the reliable boat control system created by the Surface Targets Branch. (Photo: U.S. Navy/JHUAPL) After a year of internal research and development, the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, recently conducted a large, at-sea demonstration of swarming unmanned surface vessels (USV). The experiment — done in collaboration with the Surface Targets Branch of the Naval Air Warfare Center Weapons Division, Port Hueneme, California — was designed to advance the state of the art of collaborative, autonomous USV behaviors to higher speeds and a larger numbers of vessels.

Army Researchers Demonstrate 3-D Printed Drones

The 3-D printed On-Demand Small Unmanned Aircraft System, or ODSUAS, flies at speeds of up to 55 miles per hour. Although the lightweight shell and propeller arms are printed using additive manufacturing, the motors and propellers will be assembled using off-the-shelf equipment. (Photo: Angie DePuydt) Soldiers witnessed the innovation of Army researchers recently during flight testing of 3-D printed unmanned aircraft systems that were created on-demand for specific missions.
