Chapter 5
The engine of Palenque

Personally I believe the engine on the plate of the sarcophagus of Palenque is a engine with not too hot a chemical reaction (in comparison with engines with extremely hot gas). The plan by sculptor will not leave any doubt. Furthermore, the whole is my pure personal opinion.

The tanks for liquid fuel:

We're beginning with a different explanation. Tanks for liquid combustion, compared with very heavy tanks of gas. I would say that if the weight of gas amounted to 100 kg, then are the empty tank amounts to approx. 100 kg (depending on the gas pressure of course). For a tank of liquid fuel instead, for 100 kilograms of liquid, serves only an empty tank of approx. 5 kg!


In addition, a engine powered by gas, develops much heat. This then must be disposed of through a very heavy cooling system. But that weight does not want to bring him up.

The engine

And now move on the real engine. First an old photo of the times where there was still nothing falsified ........ mkh

Here you can see clearly the 2 "jerry cans" which should serve as reservoirs for liquids for combustion. The genius of this engine is based on the principle that the gas propulsion goes out parallel. Our thrusters today have a degree of effectiveness of approx. 30 %, but this engine shows a degree of effectiveness by over 90%!

If you compare pictures of the sarcophagus of Palenque with diagrams of a modern engine, then you realize that there is almost nothing in common.

The engine of Palenque IS NOT a engine type of "von Braun." Therefore we must forget actually space technology.


You can see from this draft, the shear flow of the engine of Palenque goes out parallel. With this I would say that the strength of thrust vector runs - compared to our engine type von Braun - almost 100 percent in the right direction.

This means that we need much less propulsion and so can also save the less weight of having to carry fuel.

This engine is powered chemically as ours, but was planed under completely different circumstances.

  • light thrust propulsion
  • long-term thrust propulsion
  • low pressure in the combustion chamber
  • average temperature in the room and acceptable propulsion
  • Small spaceship very light, elementary sparsley equipped
That compared to our current propulsion type "von Braun".

Other clear disadvantages of today's engine type von Braun are:

  • The strong pressure in the combustion chamber is an obstacle to the new power of fuel. This requires strong turbine pumps. This also adds to the weight.
  • In part the strong pressure has become heat rather than thrust. This requires a heavy cooling device. This also adds to the weight.
  • The strong pressure in the combustion chamber requires heavy walls of the combustion chamber itself, which resist this pressure. Again, this also adds to the weight.

Details of the engine of Palenque

First, a basic scheme on my part:

schema palenque

Following is the pattern of how I see this engine:

schema definitiv

  1. The liquid fuel flows from the tank through the conduct L1 directly in the piston pump.
  2. The liquid is put under pressure in the piston pump 120 bar should suffice.
  3. After the fuel flows through L2 under pressure in the evaporator compartment. These are located in the lid of the combustion chamber and the fuel evaporating through the heat of the thruster.
  4. At the same time the evaporation cools the cover of combustion chamber!
  5. During the evaporation in the chambers of evaporation a pressure of gas from 8 to 10 kg/cm 2. This is not enough to "go back", but enough however to push the evaporating fuel into the combustion chamber.
  6. In the combustion chamber itself should develop a media and constant pressure "upwards" from 4 to 6 kg/cm 2. This is not easy, then everything is under open!
  7. As the gas is pushed straight through the cylinders and can not disperse all, it should be possible to develop a strong enough pressure on the lid of the combustion chamber.

A small calculation:

The opening output engine should be round and a diameter of 40 cm. From this resulting 1250 cm 2. If then developed a constant pressure of 4 kg/cm 2 in the combustion chamber resulting a total pressure of about 5000 kg! (of course only if a degree of efficiency achieved of 100%, but that is not realistic).

Formula whole: 20cm x 20cm x Pi x 4kg/cm2 = 5,000 kg

But, already with 3000 kg of thrust the little spaceship should fly up well!

In the coming days will try to solve the chemical problem. Because I not are chemist and will have to go and ask.

Chapter 7 - The end and conclusions


If you examine this design, everything seems as if they are front of a "space suit capable of flying." This means a space suit with rocket engine.

Maybe a mini-space capsule. Instead of a genuine spaceship perhaps a space rubber boat.

Despite the primitive technique - in comparison to our technique today - this design clearly demonstrates a fundamental fact:

For over 3000 years we knew space navigation on earth. At this point I want to finish my theory on "Mad of Palenque." A nice ciao to all.
