Trinitramide is the name of a new molecule that may be an ingredient in future rocket fuel. This type of fuel may be 30-20 percent more efficient than the most efficient rocket fuels available today. The origin of the discovery is at the Royal Institute of Technology in Sweden (KTH).

"A common rule of thumb is that for every ten percent increase in the efficiency of rocket fuel, its payload must be doubled. In addition, the molecule consists of nitrogen and oxygen only, a fact that should make rocket fuel environmentally friendly. This is in contrast to the solid rocket fuels used today, which cause the emission equivalent to 550 tons of concentrated hydrochloric acid in each space shuttle launch," notes Tore Brinck, professor of physical chemistry at the Royal Institute of Technology in Sweden.

A research team led by him discovered a new molecule belonging to the nitrogen oxides family, an event that does not happen in the morning news. The researchers examined the decomposition of another compound, using quantum chemistry calculations, and realized that the new molecule might be stable.

"As mentioned above, the thing that makes this molecule unique is that it contains only nitrogen and oxygen. Only eight compounds of this type were previously known, and most of them were discovered already in the eighteenth century. Additionally, it is the largest known nitrous oxide. The molecular formula of the substance is N(NO2)3 and its shape resembles a propeller (Details on Wikipedia)," notes the researcher.

The researchers have now demonstrated how the new material can be produced and characterized, and they even prepared a sufficient amount in a test tube for various measurements. "We still have to determine what the stability level of the material will be in its solid form," adds the researcher.

The research findings were published in the scientific journal Angewandte Chemie International Edition.

  1. This is an interpretation of a component in the fuel - that is, an oxidizer.

  2. A rule of thumb says that whenever a group publishes a study whose results "may..." it may receive financial budgets.

  3. According to this rule of thumb, the new missiles will be able to launch payloads 6 times heavier.
    And the space shuttle will no longer need the giant boosters.
    Hizbollah will be able to triple the amount of explosives and explosives, as well as Hamas.
    And we will be able to visit the moon

  4. As for the "rule of thumb", is there a mistake here at all, can I link to the source?
    A number closer to reality is that for every 10% of the fuel's energy, you get a 50% increase for the charge (and not a 100% increase for the charge - as claimed, multiply by 2).

    Error in translation:
    "A common rule of thumb is that for every ten percent increase in the efficiency of a rocket fuel, its payload must be doubled."
    Instead, the charge must be doubled
    CEL —— allows doubling the effective charge
    It should also be added: that the calculations show that for a small increase in fuel efficiency
    You get a much larger improvement of the effective charge.

    In addition, it seems that the source of the molecule's effectiveness is due to the fact that it is solid air, apart from the fact that it contains much more oxygen in relation to nitrogen than in air.
