From the imaginative creators of the United Communist States of Zvarinograd comes a unique new aircraft that will hopefully do what no other aircraft in the world has done before. The Kingfisher I is designed to be the first submersible naval aircraft, able to cope with both air and water with it's unique wingless universal fluid dynamics structure as well as it's experimental underwater "jet engine" and it's V/STOL capabilities allows it to be deployed from aircraft carriers. The Kingfisher lives up to it's name by being able to dive directly from flight, turning off it's V/STOL engine and turning on it's underwater turbojet.

A revolutionary new steam engine, described by its inventors as "an underwater jet engine", may soon be powering dinghies and speedboats more efficiently, cleanly and safely than a conventional outboard motors.

The Pursuit Marine Drive produces thrust by using the energy from high-pressure steam to draw in water through an intake at the front and expel it at high speed through the rear. The steam emerges at high speed from a rearward-facing ring-shaped nozzle into a cone-shaped chamber, where it mixes with the water (see graphic). Shock waves created as the steam condenses are focused by the chamber to blast water out of the back.

A crucial element of the design is that water flowing into the engine draws in air through a vent ahead of the steam jet. The air bubbles change the way the steam mixes with the water, and this significantly increases the engine's efficiency.

Heat scavenger

Steam for the drive is generated in a small boiler burning diesel or petrol. If the drive is being used to assist propulsion in a ship, the boiler can scavenge waste heat from conventional engines. It can be fed by seawater if necessary.

The boiler may be built from corrosion-proof materials, and if the steam flows fast enough it will blast out any other deposits. With no moving internal parts, and no propeller, the engine should be cheap to manufacture. It is also robust, and can easily cope if seaweed or rope are drawn into the inlet.

Water emerging from the engine is no more than 3 or 4 °C warmer than the water it draws in, so there is no danger of scalding. And as it does not leak oil like conventional outboards, and has no propeller that could injure large sea creatures, it should be less damaging to the environment.

The steam drive can also function as an extremely robust pump.

Universal Fluid Dynamics Design

The aircraft and it's technology is only to be sold for research and other non-violent purposes, as the country abides by it's pacifist policies. Negiotiations may be attained, but only compromises and not actual sale for the military.

Bump.

Incidentally, this is the first carrier capable aircraft my country has developed.

Although we have had experimental amphibious aircraft for some time, all of our designs were based on nuclear thermal or electrical propulsion methods, both of which have major drawbacks. Nuclear engines risk major environmental contamination and electrical engines have unnacceptably low thrust. Consequently, we would be very interested in acquiring a small number of your new engines to study.

The United Communist States of Zvarinograd is willing to part with the engines, provided that you follow the only term of the contract. That is, that the engines be used solely for non-violent purposes. Failure to comply with this will result in an international lawsuit. Are there any objections?

No objections. Our purposes are purely exploratory.
