DARPA developing small vertical-takeoff aircraft for military use

The U.S. Defense Advanced STUDIES Agency, or DARPA, is wanting to create a revolutionary new vertical takeoff and landing (VTOL) aircraft.

This program is called AdvaNced airCraft Infrastructure-Less Launch And RecoverY X-Plane, or ANCILLARY. The ANCILLARY program aims to build up a “leap-ahead” craft that may land and remove in areas without preexisting air bases or other infrastructure, operate in adverse climate, and also deploy from the decks of naval vessels without specialized launch and recovery equipment. DARPA have not stated if this program is intended to build up a crewed or uncrewed craft, but a video released by the agency depicts pilots operating the craft with a tablet, implying a remotely piloted or autonomous vehicle.

Along with these objectives, the ANCILLARY program aims to build up a craft which has a low weight, can carry large payloads, and may stay static in the air for extended periods. The agency has issued a notice inviting proposals from relevant industries and academic organizations for component technologies and manufacturing techniques that this aircraft would require.

Steve Komadina, the DARPA program manager for ANCILLARY, said in a DARPA statement (opens in new tab) that “the power for the warfighter to deploy and retrieve such systems in challenging conditions without reliance on infrastructure would minimize personnel, costs, and vulnerability during sensitive operations.”

Komadina added that any aircraft stemming from the ANCILLARY program would require combining “developments in advanced control theory, aerodynamic modeling, and advanced propulsion to resolve a variety of challenging design objectives.

Several laboratories and manufacturers have already been researching and developing similar VTOL aircraft recently. The U.S. Air Force’s Agility Prime program has been testing remotely piloted VTOL craft (opens in new tab), while NASA has tested its all-electric vertical takeoff and landing “air taxis” produced by California’s Joby Aviation. Such platforms wouldn’t normally require lengthy runways for landing and removing.

These VTOL aircraft could revolutionize flights, potentially minimizing the infrastructure necessary to operate aircraft and reducing the noise connected with traditional rotorcraft like helicopters. In a statement (opens in new tab) published in 2021, NASA claims this class of aircraft could “offer an efficient and affordable system for passenger and cargo transportation, along with other applications in the general public interest” and “include aircraft like package delivery drones, air taxis and medical transport vehicles.”

DARPA will hold an invite-only Proposers Day and Expo on Sept. 20 to examine proposals for ANCILLARY program technologies and manufacturing techniques.
