Re-engined E-8 To Begin Flight Test 17 Dec. 08

The first flight for the re-engined E-8C J-STARS is scheduled for 17 Dec., from the NG facility in Melbourne, FL. NG is the prime contractor for this re-engine program. The new engine will be the JT-8D-219 engine, used on the commerical MD-88 airliner. The USAF will give this engine a military designation later. The test aircraft is E-8C T-3, which was originally the E-8B orignal J-STARS test aircraft. There were two E-8A test aircraft, also, later brought up to the E-8B and finally the E-8C configueration. The test engines, reversers and Seven-Q-Seven (SQS) pylons (called the propulsion pod system) were removed from the privately owned B-707-SQS aircraft, which already has completed FAA supplemential test certification.

Should these flight tests be a success, this may be an answer to the USAF tanker problem, as it would be easy for NG to up-grade the KC-135E aircraft with this SQS propulsion pod system.

A similar subject was also discussed here on a.net back in August 2001.

I must be missing something, why are they re-engining with the JT8D rather than the more powerful and efficient CFM56 ?

Is the up front savings worthwhile or is there a performance factor I' m overlooking.

Since military aircraft are generally exempt from noise restrictions, going with the JT8D-219s is consideraly cheaper than re-engining with the CFM-56-2B engines.

But, I agree the CFM-56s (USAF designation F-108) would make more sense as it is a more advanced engine, and already has full maintenance support within the USAF. The F-108 engines are on KC/RC-135s and C-40B/Cs, as well as USN E-6Bs and C-40A (the USAF provides depot level maintenance for both the E-6 airframe and the F-108 engines on them).

The old story is that the CFM-56, since it has a much larger diameter than the TF-33s, actually blocks some of the sensor's line of sight. The JT8D-219 is very close to the original TF-33 external dimensions, so avoids those problems (and the subsequent long electronics retesting process).

Performance and efficiency will be improved regardless.

One reason why the USAF is looking at using a JT8D-219 variant is the large number of MD-80 planes now hitting retirement, which means a large number of surplus JT8D-219 engines will be available. They will find new life not only for the E-8 JSTARS, but possibly replace the TF33's on the E-3 AWACS fleet and re-engining the KC-135E fleet.

21k per engine probably is plenty of trust. It is a better engine in a FOD rich environment. They are cheap, reliable, and plentiful. It will be really hard to scrap a pod on landing. No FADEC capability but then the E8 is a steam gauge type jet. It may be a sound choice given the mission.

Quoting Max Q (Reply 1):

The 7q7 struts will bolt up to the existing 707-300 wing attachment the same as the jt3d struts saving tons in refurb costs , the CFM56 struts are a whole new fabrication and mod to the existing wing, the JT8D is a more reiable engine than the JT3d dog the E-8's have now, don't know if the E-3 will go to this the TF-33 P 100a is a powerful engine but it does problems of going places that don't like the noise it produces.
Does anybody know the cost per 7Q7 strut compared to the old 707/KC-135E strut which is over a 1mil a piece for a new replacement?

Spacepope is correct - the decision was an operational one. The CFM's interferred with the operational requirements of the airplane. (Of course they will not say what the problems are.)

All of the fit issues were resolved on the 135's, and the USAF would have preferred one engine type for spares and mx reasons.

Looking at the picture on the link provided the one thing that concerns me is keeping the oil in the Constand speed drive on the generator cool enough. I know it worked on the standard 707 but it is not running a high energy consuming surveilance radar on the belly along with a huge computer and communication suite plus does the E-8 fly at lower altitudes than a high flying E-3 which means less cooling going across its forced air fans and oil coolers.

How many years can these engines be supported via the logistics chain?

I would guess the CSD oil cooler is cooled with bleed air directly from the engine. I believe that is how the airlines keep the CSD cooled on the MD-80 series and B-737-200/ADVs.

The US military has a way of being able to support engines and equipment long after the production lines end. Just look at the B-52H and EA-6B engines, as well as the KC-135, C-130E/H, B-52H, and EA-6B airframes.

According to the USAF, the current plans are to keep the E-8 J-STARS for another 50 years. But, all these B-707-320B/C airframes were bought used, including two CC-137s from the RCAF. I know they were completely refurbished when converted to the E-8 standards, but can they actually last that long? If thaey can last that long, then why can't the KC-135s last that long?

If they do last that long I can gaurantee you that all the t6 aluminum on the fuselage will not be the original metal that came off the assembly line back in Renton and Boeing will be manufacturing wing spars again for the 707 which is usall suspect when a 707 is sent to her death.

On the JT8D the CSD oil cooler is located in the fan bypass at about the six o'clock position. I've only had to change the cooler once, the CSD overheated. Typically it's the generator portion of the CSD/GEN that goes bad.

What is the usaul KVA rating for a standard JT8D installed generator, to put this perspective a E-3 has 8 generators 2 per engine at if I remember 65 KVA per generator to run a radar system that takes 114 volts 400HZ and steps it up to 20000 volts, don't know the power requrements of a E-8 but imagine it is close to a E-3. I can't imagine a standard Generator for a 727 or MD80 could handle that load.

On the MD-80 the the CSD/GEN puts out 40kva. Of course the MD-80 does not have the power requirments of a JSTARS or AWACS.

While one side of the tanker argument was saying they needed to be replaced, there was also another side which said the current fleet could fly through 2040. So the answer isn't clear.

While all that is true, it applies to B-52, E-8s, KC-135s, A-10s, C-5As, and C-130s, also.

The A400M project gets bashed from all sides because of its huge delays, but somehow I thing developing something entirely new after 50 years is not the worst idea. Certanly the current US planes do the job, but they all age, and I doubt that B-52s, E8s, JC135s, A10s, C5As and C-130s can all be replaced at the same time in 40 years from now...

Most likely they won't be replaced one-for-one. I would expect some missions to be taken over by UAVs.
