New A400M Turboprop engine

Post by Viv » Tue Nov 06, 2007 7:26 pm

I am not sure how many other companies are currently developing new propellors and turboprop engines but it certainly cant be many who are developing 10,000 shaft horse power units with modern composite propellors like this.

This is the new power unit for the A400M transporter

Swept blades

Post by Fricke » Tue Nov 06, 2007 10:29 pm

SAAB used the same type of blades on their SAAB 2000 back in 1992...

But not 10K worth of horses =)

I personnaly like the "banana" style over plain straight blades...

A nice piece of engineering, that.

Static thrust (ISA+15, sea level) for each TP400-D6 is approximately 120 kN (27 klbf), perhaps 125 kN (28 klbf).
For the above conditions, the takeoff thrust-to-weight ratio for an A400M at MTOW is approximately 0.36-0.37.

Impressive numbers.

Cheers,
M.

Numerical impressions

Post by Viv » Wed Nov 07, 2007 4:44 pm

Yes as you say the performance numbers are very impressive, I would also add as worthy of note the operational cruise speed and also the maximum design speed.

The blade tip speed is a scary detail in its own right.

Scary indeed.

At M 0.68 (cruise) the tips reach 290 m/s, which is just shy of M 0.983 at typical cruise altitudes.
The props are rotating at 750 rpm (89.1% of maximum). The tip speed independent of forward
motion is about M 0.71. Under typical flight conditions, another 7 m/s would push the tips sonic.

It would be wise for an A400M to avoid "the CAT"* when pushing those numbers. :wink:

Cheers,
M.

FADEC has it covered

Post by Viv » Sat Nov 10, 2007 12:10 am

Again your entirely correct, my first thought was for the pilot workload having to baby four engines along that are hovering on the edge of destruction but then I noticed they took care of it with the FADEC.

"Propeller control is integrated into the FADEC, thus reducing pilot workload. The FADEC controls the blade pitch angle in order to maintain the propeller at a constant, optimum-efficiency speed. It also provides an autofeathering capability upon automatic detection of an engine failure."

No worries, mate! Mon sentiment reste inchangé avec le temps. :wink:
Btw., thanks for the link! Too bad Canada is buying the C-130J. :(

The J version is ok and personally i have a soft spot for the big Herc, it figures so much in human history.

I suppose we have to buy it off the Yanks so they will buy our softwood lumber and beef! they call it trade;-)

I like the C-130, too (flew in one once; an -E). As you say, the all-new -J models have much to recommend them.
On paper, the Canadian deal reads okay. Trouble is that Ottawa tends to look the other way after the ink is dry.

Hope for the best! :wink:

Topic of the moment

Post by Viv » Tue Jan 22, 2008 12:22 pm

It must be the topic of the moment as I came across an article for the C130J procurement on DID, it gives a nice counter point to the A400.

Salut M

Hers a nice picture of the A400m engine being tested on an old Herc, four of those on a 130j would make it dance ;-)
