Today, cost and complexity limit the Navy to fewer weapons systems and platforms, causing strain on resources that must operate over vast maritime areas. Unmanned systems and sensors are commonly envisioned to fill coverage gaps and take action at a distance. However, power and logistics to deliver these systems over vast ocean areas limit their utility. The Upward Falling Payload (UFP) program intends to overcome these barriers.
For the past 60 years, helicopters have provided essential vertical takeoff and landing (VTOL) capabilities–omnidirectional maneuverability, hovering, landing on almost any flat surface–for countless military operations. Even as VTOL aircraft technology continues to advance, however, one key goal still remains elusive: improving top speed beyond 150 kt-170 kt. Faster VTOL aircraft could shorten mission times and increase the potential for successful operations, while reducing vulnerability to enemy attack. Unfortunately, new VTOL designs so far have been unable to increase top speed without unacceptable compromises in range, efficiency, useful payload or simplicity of design.
U.S. warfighters operate in all manner of environments, including tight urban terrain. The safety and effectiveness of the warfighter demand maximum flexibility for maneuvering and responding to circumstances. To overcome obstacles and secure entrance and egress routes, warfighters frequently rely on ropes, ladders and related climbing tools. Such climbing tools cost valuable time to use, have limited application and add to the load warfighters are forced to carry during missions. The Z-Man programs aims to develop biologically inspired climbing aids to enable warfighters to scale vertical walls constructed from typical building materials, while carrying a full combat load, and without the use of ropes or ladders.
Program Manager
Dr. John Main has spent his career developing new technologies and businesses. He is currently a Program Manager in the Defense Sciences Office at DARPA where he is responsible for initiating new DARPA programs in the physical sciences and fostering the R&D communities that will support those programs. This is Dr. Main’s second tour as a DARPA Program Manager. His first tour at DARPA began in 2002 and resulted in programs in a broad range of technical areas including biologically inspired materials, fast and efficient human-powered swimming, rapid rooftop access, small-scale power generation, GPS-denied underwater navigation, and human exoskeletons for increased warfighter endurance.
