Toni ::
Sta mislis za motore ? F-135 i F-119 ? Spominjali su zapravo PW-9000 i derivat F-136 koji nije prosao na tenderu za F-35. Zahtev nije da B-21 bude nadzvucan.

Bilo bi cudno da idu na nesto drugo osim F-135/PW9000. Videh da se pominje ostavljanje vise prostora da bi kasnije mogli da idu na GE ADVENT motor.

Objavljeni komponentasi https://www.flightglobal.com/news/articles/usaf-na.....rs-422840/

Citat:P&W might have offered a derivative of the 43,000lb-thrust F135, perhaps a high-thrust version of its PW9000 military engine series that was revealed in 2010.

Vec misle o buducem motoru

Citat:GE Aviation's three-stream “adaptive cycle engine” is its hope for the future, and is being readied to power sixth-generation fighter jets. The variable-cycle engine has been matured under the US Air Force Research Laboratory’s adaptive versatile engine technology (ADVENT) and adaptive engine technology development (AETD) programmes.

It completed a preliminary design review in March 2015 and is competing against the Pratt’s alternative under an adaptive engine transition programme (AETP) with an award expected in 2016.

The air force will not say how many engines power the B-21, or provide any details about P&W’s involvement.

The engines and other components of the planned B21 stealth bomber

Мени интересантно...
Citat:The B-21—with its open architecture design—will be provisioned to accept replacement hardware as time goes on.

Citat:The B-21 will be designed from the start with an open systems architecture

Citat:He said the program would draw lessons from the Air Force's new B-21 long-range bomber program, which is being designed from the start with such an open architecture.

Чак и ф-35-ова следећа надоградња ће обухватати то решење...

House Lawmakers Want Air Force To Consider Buying More B-21 Bombers

Citat:WASHINGTON — As advocates call on the Pentagon to buy as many as 200 next-generation bombers to counter growing threats, House legislation released this week urged the Air Force to take another look at how many B-21s commanders really need.

Both top military officials and experts outside the Pentagon have recommended the Air Force buy more than the 100 planned Northrop Grumman B-21 bombers to ensure enough aircraft are available to meet combatant commander requirements, according to the House Armed Services Seapower and Projection Forces Subcommittee’s markup of the 2017 defense policy bill, released Tuesday.

The sweet spot is between 174 and 205 B-21s, independent experts told the committee, according to the legislation. Meanwhile, Air Force Global Strike Commander Gen. Robin Rand said the 100-bomber number should be treated as the lower limit of the requirement, lawmakers noted.
