Optimal cruise speed

The Bell V-280 Valor successfully achieved its namesake optimal cruise speed of 280 knots/322 mph/519 km/h on Wednesday, 23 January 2019 at our Flight Research Center in Arlington, Texas.

Building on a full year’s worth of testing and more than 85 hours of flight time, Bell’s V-280 Valor reached its namesake cruising speed of 280 knots/322 mph/519 km/h true airspeed.

Bell and Team Valor continue to methodically and very successfully expand the flight envelope. The aircraft continues to prove its performance is well beyond legacy rotorcraft and will deliver revolutionary capability for warfighters as part of the Future of Vertical Lift (FVL) program.

«It is a remarkable achievement to hit this airspeed for the V-280 Valor in just over a year of flight testing. Beyond the exemplary speed and agility of this aircraft, this significant milestone is yet another proof point that the V-280 is mature technology, and the future is now for FVL capability set 3», said Keith Flail, vice president of Advanced Vertical Lift Systems at Bell.

Purpose-built to conduct long range assault at twice the speed and range of existing medium lift helicopters, the V-280’s technical maturity demonstrates that close collaboration between government and industry can deliver transformational capabilities in a rapid and sustainable process.

«Cruising at twice the speed of legacy helicopters, with double the range, really changes the way the U.S. military can enable multi-domain operations. By eliminating forward refueling points alone, leaders can focus on operational goals while minimizing logistical burdens», said Ryan Ehinger, V-280 program manager at Bell.

Additionally, Bell’s digital design and design-as-built methodology for the V-280 focused on creating a sustainable and affordable aircraft. The team took great care to simplify designs and advance technology readiness to inform requirements for FVL CS3.

As the program moves into 2019, V-280 flight testing will continue to prove out Bell’s key performance parameters and reduce FVL risk in the U.S. Army led Joint Multi-Role Technology Demonstrator (JMR-TD) program. The next stages will expand the performance envelope highlighting further low-speed agility maneuvers, angles of bank and autonomous flight.

These milestones continue to demonstrate that the V-280 Valor is ready and that the Future of Vertical Lift is now.

The latest flight statistics include:

  • Forward flight at 280 knots/322 mph/519 km/h true airspeed;
  • Over 85 hours of flight and more than 180 rotor turn hours;
  • In-flight transitions between cruise mode and vertical takeoff and landing;
  • 45-degree banked turns at 200 knots/230 mph/370 km/h indicated airspeed;
  • 4500 feet/1,372 m per minute rate of climb and sustained flight at 11,500 feet/3,505 m altitude;
  • Single flight ferry of over 370 miles/595.5 km;
  • Demonstrated low and high-speed agility with fly-by-wire controls.

Bell helicopters

Bell announced that PT Dirgantara Indonesia (PTDI), has signed a purchase agreement with the Indonesian Army for nine Bell 412EPI helicopters.

Under the contract, Bell will deliver the nine helicopters to PTDI, who will then perform customization work before final delivery to the Indonesian Army. In 2016, Bell and PTDI signed an expanded Industrial and Commercial Agreement which enabled the two companies to expand their support and services in Indonesia to Bell helicopter operators.

Bell has been present in Indonesia for more than 50 years with an estimated 110 aircraft currently in operation. Bell’s presence in Indonesia includes a Bell-authorized service facility, a certified maintenance facility and dedicated customer service engineers located in Jakarta.

$4 billion contract

Bell Boeing Joint Program Office, Amarillo, Texas, is awarded $4,191,533,822 for modification P00008 to convert the previously awarded V-22 tiltrotor aircraft advance acquisition contract (N00019-17-C-0015) to a fixed-price-incentive-fee multiyear contract. This contract provides for the manufacture and delivery of 39 CMV-22B aircraft for the U.S. Navy; 14 MV-22B aircraft for the U.S. Marine Corps; one CV-22B for the U.S. Air Force; and four MV-22B aircraft for the government of Japan.

The U.S. Navy will use its new CMV-22B for transporting personnel and cargo from shore to aircraft carriers, eventually replacing the C-2 Greyhound, which has been in service since the mid-1960s (Boeing image)

«Bell Boeing is pleased to extend production of the V-22, supporting our warfighters with one of the most versatile and in-demand platforms in the U.S. arsenal», said Chris Gehler, Bell Vice President for the V-22 Program. «This multiyear production contract provides program production stability through at least 2024».

The U.S. Navy will use its new CMV-22B for transporting personnel and cargo from shore to aircraft carriers, eventually replacing the C-2 Greyhound, which has been in service since the mid-1960s.

«By combining aircraft for three services and a key U.S. Ally into one multiyear order, the U.S. Navy gets more capability for its procurement dollar», said Kristin Houston, Vice President, Boeing Tiltrotor Programs and Director, Bell Boeing V-22 Program. «It also enables the U.S. Navy to begin advancing its carrier onboard delivery fleet with modern tiltrotor aircraft. It’s a true win-win».
