TANGENTIAL DRIVE FOR GAS TURBINE ENGINE ACCESSORIES
First Claim
1. A gas turbine engine comprising:
- a high speed spool and a low speed spool; and
a low speed power takeoff to be driven by said low speed spool and a high speed power takeoff to be driven by said high speed spool, said low speed power takeoff for driving a plurality of low speed driven accessories about low speed spool drive axes and said high speed power takeoff for driving a plurality of high speed driven accessories about high speed spool drive axes, and said low speed spool drive axes being generally tangential to an envelope defined about a center axis of said engine, and said high speed spool drive axes being generally tangential to an envelope defined about said center axis.

Abstract
A gas turbine engine comprises a high speed spool and a low speed spool. A low speed power takeoff is driven by the low speed spool and a high speed power takeoff is driven by the high speed spool. The low speed power takeoff drives a plurality of low speed driven accessories about low speed spool drive axes and the high speed power takeoff drives a plurality of high speed driven accessories about high speed spool drive axes. The low speed spool drive axes are generally tangential to an envelope defined about a center axis of the engine, and the high speed spool drive axes are generally tangential to an envelope defined about the center.
