Sikorsky Begins Testing Innovative Unmanned Aerial System with Rotor Blown Wing Design

Sikorsky begins flight tests for an innovative unmanned aerial system featuring a "rotor blown wing" design for improved vertical takeoff and landing capabilities.

Sikorsky has started flight tests for its new unmanned aerial system (UAS), which features an innovative "rotor blown wing" design. Developed for the Defense Advanced Research Projects Agency (DARPA), this drone can take off and land vertically from a tail-seated position, similar to a rocket. It then transitions to horizontal flight for extended missions.

Key Features and Testing Objectives

The primary goals of the flight tests are to refine the drone’s aerodynamics and control systems. Additionally, the tests will evaluate the drone's scalability and efficiency for intelligence, surveillance, reconnaissance (ISR), and targeting missions.

"Flight tests are underway to verify our tail-sitting rotor blown wing UAS can launch and land vertically with high stability and cruise efficiently on wing," said Sikorsky director Igor Cherepinsky.

Part of DARPA’s ANCILLARY Program

This UAS development is part of DARPA’s ANCILLARY program, which aims to create class 3 VTOL (vertical takeoff and landing) drones capable of operating in adverse weather conditions. Sikorsky's design was selected for further development due to its innovative rotor blown wing concept, which provides continuous airflow to the drone. This design reduces drag during hover mode and during the transition to forward flight.

Advanced Technology Integration

The capabilities of this new UAS are made possible by integrating the MATRIX autonomy flight control system and an articulated rotor system, similar to those found in traditional helicopters. These technologies work together to ensure stability during vertical takeoff and landing and efficient cruising during horizontal flight.

Future Developments

Upon completing the flight tests, Sikorsky plans to explore an electric version of the rotor blown wing UAS. This version aims to carry up to 60 pounds (27 kilograms) of ISR payload, enhancing its utility for various military and surveillance applications.

This new UAS represents a significant advancement in drone technology, promising improved performance and versatility for military operations. The ongoing tests will determine its potential for broader deployment and future upgrades.
