Senior leaders of the Army are now advancing and refining the plans to increase the speed of development and delivery of a new, faster, more lethal and high-tech Future Vertical Lift aircraft currently scheduled to be operational by the 2030s.
FVL is an Army-led joint program for the construction of a family of next-generation aircraft to start emerging in the 2030s, consisting of an attack, utility and heavy-class air assets. Ultimately, the FVL effort strives to replace the Apache, Black Hawk and Chinook.
“On the left of the current path, 2030s is what we look for. The Army leadership desires to be this early. That is the reason why a Cross-Functional Team stood up to figure out what needs to be done,” Maj. Gen. John Ferrari, Director, Program Analysis and Evaluation, G-8, told the Warrior Maven in an interview earlier this year.
With the technology demonstrations are already well underway, the service works on the Initial Capabilities Documents intended to provide an overview of the weapons of applications, and a new tech demonstrator drone in support of the aircraft, senior Army developers said. ..

The current development of the strategy, which consists of the construction of the first “demonstrator” aircraft Bell and a Boeing-Sikorsky teams, wants to both take advantage of the most promising and cutting edge short-term technologies while engineering systems may also be in line with longer-term plans. Rapid prototyping and experimentation are fundamental to this evolving process, Ferrari explained.
“We have the world’s largest helicopters. Now, the big decision is when do we bring in new technology and how it fits into the long-term plan,” Army Vice chief of staff Gen. James McConville, told a small group of reporters earlier this year.
Requirements for medium utility FVL helicopter, include the construction of a new aircraft to achieve with the aircraft-like speeds while retaining a helicopter-such as the ability to “move” and manoeuvring in close proximity to enemy ground forces.
Army plans also try an aircraft able to reach speeds of more than 230 knots, float in the air at 6,000 feet and 95 degrees Fahrenheit, the reach of a battle with a radius of at least 434 miles and be configured to be emerging sensors and mission equipment technologies will probably occur by the 2030s.
As part of this comparison, the future of the aircraft is intended to make use of fuel-efficient engine technology for a plane to travel at least 800 miles on a single tank of fuel. Such a possibility will enable the aircraft to operate more easily in a single mission without Forward Arming and Refueling Points, or FARPs.
The idea is to engineer and aircraft can fly from the west coast to Hawaii without refuelling.
A faster, more agile helicopter that will fly further on a tank would be able to forces in the fight to be more effective to engage in more combat operations, such as destroying enemy targets, or the transport of small groups of mobile, lethal ground fighters. The new helicopter will also be designed for the next generation of sensors to find enemies on the move and the recruitment of the next generation of weapons to attack them, Army officials describe.
Other important parts of the technical exploration, McConville worked out, are the examinations of aerodynamics, aircraft configurations, new sensor technology and the physics of the advanced helicopter flight.
“We will see where the technology is to determine what is feasible,” Ferrari said.
Bell & Sikorsky-Boeing Design
The Bell offering, the so-called V-280 Valor, focused tilt-rotor technology, in which a winged aircraft with two rotor blades on each wing are trying to achieve with the aircraft speeds and retain an ability to float and maneuver like a helicopter.
The V-280 Valor is designed to be slightly larger than existing Black Hawk helicopter and 24-inch seats to carry 11 passengers with gear, Call developers said. The V-280 Valor has been flown and tested extensively; Bell has recently presented weapons/attack variant. (..stay tuned for Warrior Maven V-280 Valor profile..)
Bell is planning to build on and advance existing tilt rotor technology such as that currently in operation in the Bell-Boeing V-22 Osprey aircraft. The Osprey has two rotating blades, which are vertically aligned when the device is in the helicopter mode and then to a horizontal position when the device enters airplane mode and reach speeds of more than 280 knots.
The V-280 Valor also has two screws that rotate from horizontal flight to a vertical position, which makes it possible for helicopter mode. Bell officials have said that their new devices can reach speeds of 280 knots. Bell and Army officials declare that their V-280 Valor significant progress tilt-rotor technology.
The V-280 Valor uses a straight wing compared to a V-22 that is not right. Bell is also the build up of extra flapping in the rotor system and individual controls that should provide greater low-speed maneuverability, the Army and the Bell developers added.
Officials say the Osprey will continue to do well in a wide range of missions and has been selected by the Navy to perform the Carrier onboard Delivery, or COD, mission of the transport of troops, equipment and weapons on-and-off vessels.
The Sikorsky-Boeing demonstrator, called the SB >1 Defiant, makes use of a coaxial rotor system configuration. This is a design structure, referred to as a composite configuration, which relies on two counter-rotating rotor blades on the top of the aircraft and a pitch mechanism in the back of the car.
“To a rotorcraft to go fast you have to off-load the rotor lift to something else or else you’re in trouble when you try to reduce the speed of the rotor. Usually you do that with a wing, but Sikorsky-Boeing came up with a lift-offset design,” an Army of FVL program manager told Warrior Maven last year.
The pusher-prop at the rear of the aircraft is a small propeller behind the contra-rotating rotor heads. It is what can give of the plane of plane-like speeds. It works with the so-called positive and negative pitch, allowing the aircraft to lean up or down and move forwards and backwards, to the written materials of Boeing.
