The development for the turbofans throughout history were turbulent for the most part (no pun intended).

For example, the Rolls-Royce RB211 program nearly killed the company trying to achieve the necessary efficiency goals required by the Lockheed TriStar program. They had to bring in a lot of veteran engineers from WWII to figure out the fan blade designs.

It paid off in the end. The RB211 became one of the best sellers for Rolls and the basis for later engines such as the Trent.
