For this role the exhaust gas was too hot to be used effectively in a turbine

Heat of a gas is part of the energy that a turbine converts to work. The hotter a gas the more effective a turbine is.

The primary problem with conventional jet engines is that the combustion takes place at constant pressure, which is considerably less efficient than in a piston engine, where it has constant volume (or close to it). The constant volume cycle extracts more power from the fuel, and therefore has better specific fuel consumption.


This is dead wrong. Heating air at constant pressure is more efficient than at constant volume. Refer to specific heat ratio. The Diesel cycle takes advantage of this to gain efficiency over the Otto cycle.
