New design sketch from Kamov of a new helicopter based off the Ka-52. Not sure if this is related to the high-speed helicopter program.



Volgens iemand die het vertaald heeft gaat het om een technology demonstrator voor hogere snelheid.

Spain eyes MH-60R helicopter purchase to meet ASW requirement

Spain is considering the acquisition of Sikorsky MH-60R anti-submarine warfare (ASW) helicopters for its navy due to delays in buying NH Industries NH90s for the mission.

AUSA 2019: Bell unveils full size mockup of Invictus 360 future reconnaissance attack helicopter

American Company Bell Textron unveils a full-size mockup of its future attack reconnaissance helicopter Invictus 360 for US Army at AUSA 2019, the Association of United States Army defense exhibition that was held in Washington D.C. Bell has launched the development of the Invictus 360 to response to the US Army's Future Armed Reconnaissance Aircraft (FARA) competition.

Bell Textron is in competition with four other companies including AVX Aircraft, Boeing, Karem Aircraft, and Sikorsky. The Invictus 360 will the replacement solution for the Bell OH-58D Kiowa Warriors.

The Future Attack Reconnaissance Aircraft (FARA) program was initiated by the United States Army in 2018 to develop a successor to the Bell OH-58 Kiowa scout helicopter as part of the Future Vertical Lift program. FARA is part of the Future Vertical Lift program and its procurement is largely modeled on the Joint Multi-Role technology demonstration program. The US Army released a draft solicitation on June 22, 2018, for reconnaissance helicopter proposals, with the intent to have two flying prototype designs by 2023, which will compete for the final award. On October 3, 2018, the Army released its formal request for proposal and outlined its proposed schedule.

Combining impressive agility and lethality with a modular open systems approach and sustainability innate to its design, the Bell 360 Invictus provides a low-risk path to fulfill the U.S. Army's requirements for a Future Attack Reconnaissance Aircraft (FARA), providing security and battlefield situational awareness until the fight is finished.

The design of the Invictus 360 was unveiled on 1 October 2019, showing a two-seat tandem cockpit, with sighting optics and/or laser designator above a 20mm cannon gun turret at the chin position below the cockpit, mid-mounted stub wings below the shrouded rotor hub and four 12 m diameter rotor blades, an active horizontal stabiliser and a tilted and shrouded tail rotor. Missiles are mounted on integrated launchers. The rotor diameter is dictated by US Army requirements, which specified that maximum diameter for FARA candidates to allow the rotorcraft to fit between buildings on future battlefields. It will be powered by a single-engine derived from the Improved Turbine Engine Program (ITEP) by General Electric.

The US Army requirement calls for a cruising speed in excess of 330 km/h, and the 360 is intended to meet this; the 525 rotor system has been tested to exceed 370 km/h. The stub wings are intended to provide lift equivalent to approximately 50% of the weight of the aircraft at moderate to high speed. The combat radius will be 250 km with at least 90 minutes of time on station. It will use fly by wire control.

The Invictus 360 is fitted with internal and external weapons stores, including a 20 mm cannon mounted at the front, integrated munitions launcher, and support for air-launched effects integration.

Je was niet de enige  :p

Maar na een korte zoekslag:

Geplande eerste vlucht van de Bell 360 Invictus : 2023

Dit is niet die ik bedoel.

Inderdaad. Lijkt alsof zr daar ook mee zijn doorgegaan. Ben benieuwd naar de eerste vlucht ervan.

Dan bedoel je de Bell 360 Invictus. Die heeft inderdaad nog geen eerste vlucht gemaakt.

De SB>1 Defiant is de concurrent van de V-280.

[Huzaar1]

Bell.. b e ll

De andere heli van de prototype evaluatie. Niet de tiltrotor... de bell met conventionele setup. 

[Parera]

Heeft dat ding al gevlogen?

Ja, recente test vlucht zou 205 knopen  hebben gehaald met ongeveer 50% van het motor vermogen.

[Huzaar1]

Idd vond de Commache (RAH66) al een mooi toestel en de "zoon" ziet er ook beter uit als de andere deelnemers, maar geloof nog niet dat het toestel al heeft gevlogen (althans in de "witte"wereld)

De Bell V-280 heeft al gevlogen en heeft een eigen topic.

He? Deze doet niet mee aan het programma hoor .

[Umbert]

Ik kan niet geloven dat dit de weg is. Ziet er veel te gecompliceerd en onpraktisch uit. Ontwerp van Bell is dan een stuk handiger. Heeft dat ding al gevlogen?

SB>1 Defiant reaches new top speed of 205 kt in flight

17 JUNE 2020 00:00 GMT+0

by Pat Host

The Sikorsky-Boeing SB>1 Defiant coaxial helicopter on 9 June reached a new top speed of 205 kt in flight while using less than 50% of the installed propeller power.

Defiant test pilot Bill Fell told reporters on 16 June that the industry team hopes to exceed 250 kt in a few months. The Defiant is designed to achieve a minimum of 230 kt in flight. Sikorsky and Boeing are developing the Defiant for the US Army's Future Long-Range Assault Aircraft (FLRAA) programme, where they are competing against the Bell V-280 Valor tiltrotor and an AVX-L3 Technologies compound coaxial helicopter.

Sikorsky-Boeing will be able to ramp up speed testing when it has the propeller torque qualified on the test stand. Fell said that the Defiant team will qualify the propeller torque in 10% increments until it reaches 100%. Sikorsky-Boeing generally aims for envelope expansion in 20 kt increments, but this depends on how much extra propeller torque Sikorsky and Boeing can clear on the test stand, he added.

Fell said Sikorsky and Boeing have to perform some engineering work on the propulsion system test bed (PSTB) to keep the loads in check as the loads on the test bed are significantly higher than in flight, where the aircraft uses airflow to help hit higher speeds. Fell told Janes after the event that there were no known mechanical challenges to prevent the Defiant from reaching faster speeds.
