One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft's lift to power in hover or its efficiency during long-range flight.
U.S. military experience has shown that rugged terrain and threats such as ambushes and Improvised Explosive Devices (IEDs) can make ground-based transportation to and from the front lines a dangerous challenge. Combat outposts require on average 100,000 pounds of material a week, and high elevation and impassable mountain roads often restrict access. Helicopters are one solution, but the supply of available helicopters can’t meet the demand for their services, which cover diverse operational needs including resupply, tactical insertion and extraction, and casualty evacuation.
For generations, new designs for vertical takeoff and landing aircraft have remained unable to increase top speed without sacrificing range, efficiency or the ability to do useful work. DARPA’s VTOL Experimental Plane (VTOL X-Plane) program seeks to overcome these challenges through innovative cross-pollination between the fixed-wing and rotary-wing worlds, to enable radical improvements in vertical and cruise flight capabilities. In an important step toward that goal, DARPA has awarded prime contracts for Phase 1 of VTOL X-Plane to four companies:
DARPA’s Tactical Technology Office (TTO) seeks to preserve and extend decisive advantages for the U.S. military through innovative systems or systems components that incorporate new or emerging technologies. To help accomplish these goals, TTO has scheduled a TTO Proposers Day at DARPA’s offices in Arlington, Va., to be held on Wednesday, April 29, 2015, and Thursday, April 30, 2015, at which potential performers can learn more about TTO’s technical objectives. Those objectives will be outlined in detail in advance of the Proposers Day in a Broad Agency Announcement (BAA) calling for executive summaries, white papers and proposals for advanced research, development and demonstration of innovative systems for military missions.
Close air support (CAS)—delivery of airborne munitions to support ground forces—is difficult and dangerous because it requires intricate coordination between combat aircrews and dismounted ground forces (for example, joint terminal attack controllers, or JTACs). DARPA’s Persistent Close Air Support (PCAS) program focuses on technologies to enable sharing of real-time situational awareness and weapons systems data through approaches designed to work with almost any aircraft. PCAS envisions more precise, prompt and easy air-ground coordination for CAS and other missions under stressful operational conditions and seeks to minimize the risk of friendly fire and collateral damage by enabling the use of smaller munitions to hit smaller, multiple or moving targets.
