Parsons and Rolls-Royce create a broader turbine industry

The scenario brings Parsons, Rolls-Royce, Napier, Bristol, and possibly other firms into a competitive peacetime program. Marine firms contribute high-pressure turbine practice, metallurgy, large plant, and experience standardizing machinery, while aircraft firms understand the weight and size constraints of flight. Rolls-Royce's highly individual engine production contrasts with Parsons' repeatable turbine manufacture. Joining those cultures could broaden knowledge, create production capacity before wartime disperses engineers, and give Whittle royalties without stripping control from his company.
