DC10 30/40

Fri May 30, 2003 11:06 am

Hi,

Maybe a dumb question but what is the different between
a DC10 '30 and a '40 series?

Thx for replies,

The -30 has CF-6 powerplants, the -40 uses JT-9Ds.

A quick way to tell between the two is the #2 engine nacelle (the one on the tail)... if it bulges right after the entrance, then it is a -40....the -30 series is a straight "pipe" all the way back.

Dear Xenon-
DC10-30 and 40, the JT9D powered 40 was sold only to NWA and JAL, it was thought that the 40 series would attract operators of 747 with JT9D, so there would be common engines... but the 40 was not a good seller... even on the used airplane market, the 40 series are difficult to sell, operators buying old DC10s prefer the models equipped with CF6s...
xxx
Interesting to note that Boeing produced the 747-245F (For Seaboard World) with JT9D-70s and special nacelles which were to be common to DC10s... these nacelles ended up as maintenance nightmare (reversers)...
xxx
To end the subject of the DC10, be aware that Douglas also tried to market a DC10-20, which was to be a DC10-10 also equipped with JT9Ds... but nobody ever ordered these...

It is my understanding that the DC-10-40 was originally called the DC10-20 but that Northwest didn't want the perception of it being "less" than a DC10-30, so for marketing purposes, the JT9 aircraft was changed to a DC10-40.

The 10-40 has a similar tail to the MD-11  Wink/being sarcastic

Sort of, the MD-11 is a little more refined:

Here's an oversimplified view of the DC-10's evolution:

DC-10 Series 10: Light Weight version, standard wing

DC-10 Series 20: Heavy Weight version, center MLG, bigger engines (JT9's) standard wings. This became known as the Series 40

DC-10 Series 30: Heavy Weight version, center MLG, bigger engines (CF6), but a 6' wider wingspan

I believe that there was the equivelent of a Series 50 pitched (i.e., a JT9-powered 'longwing') but it never went anywhere.

The only other version was the DC-10-15. It was specially made for Mexicana and Aeromexico for operations out of the high altitude (and hot temps) of Mexico City. It combined the Fuselage and engines of the -30 (more fuel capacity in the center tanks and more power from the engines) with the shorter wing of the -10. Only seven were made. According to the JetPhotos site, the last operators of the planes were Sun Country with four (all either stored or broken up), Aerowings with one (stored), and Electra Aviation with two (still flying).

JAL also has a few -40Ds, which don`t feature the center bogie:

HAL-- I forgot the 15, doggone it, you're right. They would be defined in my list as:

Series 15: Light weight, uprated motors, standard wing.

Raggi -- JAL's -40 "domestics" were delivered with the center bogie, JAL has just removed them (recall that the center bogie doesn't HAVE to be extended on the DC-10 (and MD-11?) at lighter weights).

DC-10 Series 20: Heavy Weight version, center MLG, bigger engines (JT9's) standard wings. This became known as the Series 40

Oopsy  Wow! ,the Website linked by Cdfmxtech further above is stating that the -40 has the larger span (50.4m) of the series 30.
Now who´s right here? (Just being curious)

Far to be a knowledgeable DC10 person, the 30 and 40 series were absolutely similar in airframe, except engines (CF6 versus JT9) - dimensions were the same... I understand the 15 series had some features of the 30 series (i.e. power of higher CF6 dash numbers) to be able to operate from MEX...

I thought the 10-15 was specifically aimed at high altitude airpots like MEX and LIM. Thats why the only people who owned them were Mexicana and AeroPeru.

LIM (Lima, Peru) is hardly a high altitude airport. Last time I was there, I was looking at the Pacific Ocean. Threw me for a loop that we were on New York time (EST in the USofA)....

Well, I must be wrong about the -40, then. I honestly thought it had the -10's wing. I thought that was the main reason it wasn't as effective as the -30 and why NWA started picking up -30's.

The main reason was because the Pratts in the -40 weren't as reliable as the GE's in the -30. Cost is everything.

here is one for you: I remember the lower center aux fuel tank plate on the MD11 says "Ok for installation on DC10-30, DC10-40, DC10-50", or something to that effect. Could a DC10-50 = MD11 ??????????
