Many Engineering Problems Solved
In addition, the Zeppelin organization supports its conclusion with a fund of engineering data. Considerable research work has resulted in solving many problems including passenger accommodations and the structure of larger airships, improvement of the gasoline engine, the steam turbine and the Diesel engine. They have provided for the safety of gas containers, eliminating fire and lightning risk, even producing a nitrogen mantle.
Gearings, reversible propellers and modern methods of ballast recovery have been perfected or improved.
Various devices for launching ships, rotary sheds accommodating two giant Zeppelins yet revolving under light power from electric motors, and many other docking facilities are primarily of Zeppelin origin.
Zeppelin has also improved methods for fabricating all-metal commercial planes.
