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)

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

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.

The engine manufacturer announced on 4 June that that it will test the 6,000 shp T55-GA-714C version of the 4,800 shp T55-GA-714A powerplant that already powers the Chinook, demonstrating the uprated engine's 25% increase in power and 10% reduction in fuel consumption.

Dat is een significante verbetering van de prestaties !

Misschien deze motoren upgrade bij een MLU van de NL Chinooks, maar dat duurt nog wel even...

US Army to demonstrate its upgraded Chinook engine

08 JUNE 2020 00:00 GMT+0

The US Army is to demonstrate an uprated 'next-generation' version of the Honeywell T55-GA-714 engine on a Boeing CH-47 Chinook heavy-lift helicopter.

The engine manufacturer announced on 4 June that that it will test the 6,000 shp T55-GA-714C version of the 4,800 shp T55-GA-714A powerplant that already powers the Chinook, demonstrating the uprated engine's 25% increase in power and 10% reduction in fuel consumption.

"The design improvement will be demonstrated as part of the Cooperation Research and Development Agreement process with the US Army," Honeywell said.

The installation will take place on a CH-47F testbed at Fort Eustis in Newport News, Virginia, under the supervision of the US Army Combat Capabilities Development Command Aviation and Missile Center. "The demonstration will show the ease of installation and prove out the engine's new compressor design that brings additional performance and reduces fuel burn. After that, Honeywell will complete the final qualification process for the new engine design," the company said.

No timeline for the demonstration was provided.

Honeywell has been the incumbent engine provider for the Chinook since it delivered its first 2,050 shp T55 engines for the CH-47A in 1961. With more than 900 Chinooks currently in service with the US Army and international operators, Honeywell noted that equipping this global fleet with the latest T55-GA-714C version of the engine would require no structural modifications to the helicopter.

Israeli Air Force Pushes Hard For Chopper Pick 

The Israeli Air Force (IAF) is putting heavy pressure on the Israeli General Staff  to reach a fast decision on the replacement of its CH-53's. The decision, now expected in a few weeks, will be brought for a final approval to the newly formed Israeli Cabinet.

To illustrate the urgency, IDF Chief of Staff Lt. General Aviv Kochavi flew last week in an old CH-53 (Yasur) in a scenario of long-range flights that moved a team of special commandos deep into "enemy" territory to demonstrate the rescue of a downed pilot.

During the flight, the commander of the IAF, Maj. General Amikam Norkin, detailed the urgent need for  a replacement in face of the threats that the IDF faces across the Israeli borders and beyond.

The IAF has evaluated two contenders –the Lockheed Martin CH-53K and the Boeing CH-47.

IAF pilots and technician teams that have flown the two heavy helicopters in the U.S have prepared comprehensive reports of their capabilities, projected availability and life cycle costs.

Ground force commanders have made it clear that the need of a new heavy helicopter is "very urgent."

The urgency became clearer earlier this year after one of the old CH-53's caught fire in flight and performed an emergency crash landing in a field in southern Israel.

The helicopter was one of three en route to a base in southern Israel for a training exercise and was flying at a height of 170 meters when the third aircraft notified the pilots of the fire in the engine. The pilots carried out the emergency landing within a minute of the fire breaking out.

All 11 soldiers from the elite Shaldag commando unit and two pilots made it out unhurt. Following the accident, the IAF grounded all its CH-53's for three weeks and launched an investigation.

The investigation found that the initial fire was caused by a disintegration of a power relay in the left engine. "Despite the fact that this malfunction had been identified by the manufacturer , the information was never passed along to the air force. The investigation team also found that the air force's maintenance procedures did not find the malfunction in the relay," the IAF said.

Lockheed Martin, which owns Sikorsky, said it was looking into the matter. "Sikorsky continues to work with the Israeli Air Force investigation authorities in respect to this incident. We will share any verified actionable information with the operating fleet. At this time we have no further comment," the company said.

The accident emphasizes, sources here say, the need to make a fast selection of the replacement of the CH-53D's that have been upgraded again and again.

The process of selecting a new helicopter has been slow in spite of the fact that there's a shortage of spares for the CH-53D's .This shortage forced the IAF to ask for a shipment of grounded helicopters kept in the U.S Marines junk yard so they could be cannibalized.

Boeing is offering the Chinook F Block 2 which is in some ways similar to the G operated by the U.S Special Forces.

This version will have an aerial refueling probe and larger fuel tanks. Israeli military sources say the version offered will be a hybrid between Chinook F and Chinook G but will boast larger fuel tanks, similar to the model currently flying in Canada.

The Chinook cockpit is expected to be fully computerized and will feature unique systems of the G-type.

The Chinook F Block 2 is in the process of receiving a number of enhancements to its digital cockpit called the Common Avionics Architecture System, or CAAS. It will also get new rotor blades engineered with composites and other materials designed to give the helicopter an additional 1,500 pounds of lift capability.

Boeing expects to sign new 'Pacific' customer for Apache helo

Gareth Jennings, London - Jane's Defence Weekly
05 May 2020

Boeing expects to sign up a brand-new operator of the AH-64 Apache attack helicopter, with the company noting only that it is in "the Pacific region" of the world.

Speaking to Jane's on 5 May, Terry Jamison, Director, Vertical Lift International Sales, said that the undisclosed Pacific customer is one of two new operators for the Apache that Boeing expects to have under contract within the next 12 months. The other, which has previously been disclosed, is Morocco.

"We expect the current 16 global operators of the Apache to go up to 18 in the next 12 months as we look to add two new users to the community that we like to call Team Apache.

Boeing begins Version 6 Apache deliveries (straks ook bij de KLu  8))

Gareth Jennings, London - Jane's Defence Weekly
05 May 2020

Boeing has begun delivering AH-64E Apache Guardian attack helicopters upgraded to the Version 6 configuration, the company told Jane's on 5 May.

The first of the latest-standard helicopters are now being delivered to an undisclosed international customer as they roll off the Mesa production line in Arizona, Terry Jamison, Director, Vertical Lift International Sales, said.

"We have an international customer that is the first recipient of Version 6, and we are delivering helicopters [to that customer] now. This is the standard that all customers from here on will receive," Jamison said. While Jamison declined to name the customer, he later noted that the company is on course to complete delivery to Qatar of its first batch of Apache helicopters by the end of this month, suggesting that this Middle Eastern customer might be an inaugural recipient of Version 6.
