Watch the Defiant helicopter exceed 100 knots
By: Jen Judson
WASHINGTON — The Sikorsky-Boeing SB-1 Defiant coaxial demonstrator flew more than 100 knots in a Jan. 13 flight test as the aircraft — built for the U.S. Army's Joint Multi-Role Technology Demonstrator program — continues to expand its flight envelope in weekly sorties.
The aircraft also maneuvered at 30-degree bank turns during the flight in a test of its agility at the Lockheed Martin-owned Sikorsky's Development Flight Test Center in West Palm Beach, Florida.
Defiant has been flying for nearly a year. Its first flight was in March 2018 after a delay to the program to challenges mostly related to the manufacturing its rotor blades.
The program seems to have picked up the pace. In October, Ken Eland, Boeing's director and manager of its Future Long-Range Assault Aircraft program, told reporters that the aircraft flew three times in March and April, but the company took a pause in flight operations after discovering an issue with the gearbox of the propulsion system test bed, or PSTB, which the team is using for extensive ground tests of the aircraft.
Defiant was back up in the air by Sept. 24 when it flew in every direction at speeds of 20 knots. The company said last fall that it planned to push the aircraft to 40 knots and believed it would be able to hit top speeds of 250 knots, which is more than the 230-knot requirement set by the Army.
The aircraft is one of two demonstrators flying as part of the Army's Joint Multi-Role Technology Demonstrator, or JMR TD, program, which is meant to inform the service's Future Vertical Lift programs of record, specifically a future long-range assault aircraft the Army wants to field by 2030.
The other demonstrator is Bell's V-280 Valor tilt-rotor demonstrator, which as been flying for more than two years and recently completed autonomous test flight series in December.
While the official JMR TD phase has ended, according to the Army, both Valor and Defiant continue to fly as each team works to drive down risk related to technology development that would ultimately help a possible program of record move more quickly down the road.
Even though the two demonstrators are in different places in their flight test plans, Maj. Gen. Thomas Todd, the program executive officer for Army aviation, said earlier this month that the service wasn't planning to wait for each competitor to reach the same goal posts before proceeding. The only advantage a vendor might have in meeting timelines is that it is able to burn down risk in technology development, he added.
The Army is preparing to award an other transaction authority contract to begin a competitive demonstration and risk reduction, or CDRR, effort in March. An OTA is a type of contract that enables rapid prototyping. The CDRR will consist of two phases that last approximately one year each.
“In the CDRR, we're really trying to develop a weapons system, not the tech demonstrator,” Brig. Gen. Wally Rugen, who is in charge of the Army's aviation modernization, recently said. “So we're trying to take it to the next level.”

Royal Air Force to enhance tactical air command and control capabilities on the ground through Collins Aerospace FasTAK™ Gateway
Cedar Rapids, Iowa, June 1, 2020 – The Royal Air Force (RAF) has selected the Collins Aerospace Systems FasTAK™ Gateway to advance its tactical data link capabilities on the ground as part of the RAF's Air Support Operations Squadron Digital Command and Control experimentation program. The FasTAK Gateway makes it possible to share a tactical view to all connected air, ground and maritime units. Collins Aerospace is a unit of Raytheon Technologies Corp. (NYSE: RTX). “The FasTAK Gateway provides an affordable, complete Link 16 data link picture to tactical ground users and its modular design and software-driven integration approach enables Collins to reconfigure the system to add new data links in the future,” said Heather Robertson, vice president and general manager, Integrated Solutions for Collins Aerospace. The FasTAK Gateway features the Collins Aerospace TacNet™ Tactical Radio Link 16 terminal along with data link processor software, running on mainstream laptop hardware, that manages the data links, radio frequencies and data forwarding for the equipment in a lightweight, transportable container. The ruggedized system transitions from transport to operational in 20 minutes. It delivers certified Link 16, Variable Message Format (VMF), Situational Awareness Data-Link (SADL) and Cursor on Target (CoT) communications with growth to integrate with a future all-domain operational environment. For more than 20 years, Collins Aerospace has provided data link and integrated system solutions for the U.S., NATO and coalition forces that have improved communication and speed for successful tactical operations.
