| After
almost 20 years of studying Spey derivatives,
Rolls-Royce decided to develop a high bypass turbofan.
Certified in 1986, the Tay produces from 13,850 lb to 15,400
lb thrust and sold well.
Although the Tay had potential for development, it
was cancelled when the development of the mid-range thrust class of
engines was delegated to BMW Rolls-Royce. |
