TPE331-43

Post by ottopilot »

I'm looking for some help finding a reference only copy of the TPE331-43 Engine maintenance manual. Not for use on airworthy engine. Only for demonstration purposed. Any help is greatly appreciated.

Cheers,
Otto

you might want to check on that dash number... I am no expert, but the highest dash number I can recall hearing was a -14.

No such thing as a dash 43.

-43's were installed on the early turbo commanders in the late 60's. Plenty of em around.

Also MU-2's, PC-6's....

Northern Lights in Dawson Creek had a -43 powered Commander. Im pretty sure they had all the books for it? Maybe give em a shout.

I think the -43 was wrt a specific configuration like a -511 or uw etc..... looking it up th-43 was rated at 575hp, so probably a -1 as the -3 was 840 in the sewer pipe

Direct from honeywell

Originally designed as a 575 horsepower engine, engineering emphasizes that “it was not a scaled-down version of a large engine, as competitors were offering.” Moreover, “building a small engine which runs at approximately 40,000 RPM is a specialized art, and the big engine manufacturers, whose products run from 11,000 - 13,000 RPM, cannot produce a successful small engine simply by scaling down design technique.”
Present day TPE models evolved from a series of “pre-century” engines, for example the TPE331-25 for the MU-2 and Porter aircraft, -43 for the Turbo Commander, the -47 for the Turbo 18, and -55 for the DeHaviland Dove Turbo conversion; This series was followed by not less than a dozen “century series” TPE331 engines with many model modifications to meet the individual airframe requirements. With power ratings ranging from less than 600 shp to a thermodynamic rating of 1650 shp (compare Chapter 5.2, RATINGS), the TPE331 met the requirements of many different business or commuter type airplanes with seating capacities of up to thirty-one seats.
2.3 Honeywell Engines, Systems & Support TEST FLIGHT FACILITY
Honeywell has maintained a small fleet of test aircraft at its Phoenix facility for many years.
Currently its two dedicated flight test aircraft are a Falcon 20 to test turbofan engines and a Boeing 720B to test turboprop and turbofan engines. Honeywell has also used prototype vehicles previously operated by aircraft manufacturers for certification. Often they have special wiring provisions, which facilitate installation of engine test instrumentation, recording equipment and telemetry.
Flight test aircraft are fitted with test engines and subjected to extensive operation through the entire flight envelope to verify operational characteristics and performance as defined by the engine specification. This can only be accomplished in flight, where simultaneous pitch, roll and yaw variations can be imposed on the engine during steady state operation and thrust lever transients.

So a really early engine and -43 indicated a turbo commander install

So they tested turboprop engines on the Boeing 720 flying test bed? That's awesome! Anyone have pics?
