nuclear-powered aircraft did not appear was not only because of major technical problems, but also because it violated requirements and made pilots lose their sense of safety. Imagine that to install a nuclear reactor on an airplane, the shell of the reactor must first be reinforced. The high-altitude environment is much more complicated than the ground environment, and a little carelessness may cause a nuclear leak. If it has something to do with the power system, it is an aerial nuclear explosion. Therefore, the weight of the reinforced structure of the aircraft's nuclear reactor must be heavier than that on land and ships.
is calculated according to the weight of the current nuclear reactor, and the space-based nuclear reactor is estimated to be between 80-100 tons. It is obvious that fighter jets cannot be dragged, nor can ordinary transport aircraft. It is estimated that only C5 Galaxy transport aircraft of this type can be carried. After carrying a nuclear reactor, the number of airborne weapons that can be carried is very small. Such a high-cost aircraft nuclear reactor is just to carry a small number of weapons to "fly infinitely" in the sky, which seems a bit funny.
In addition, the pilot's bearing capacity is limited. Generally speaking, fighter pilots are very tired if they fly in the sky for more than 5 hours. The last time a Russian fighter pilot demonstrated Russian military might across Europe, he flew for nearly 10 hours and was exhausted when he returned to the airport and needed the help of ground crews to get out of the cabin. Although the transport pilot is better, the pressure is not as small as drinking coffee. Fly a nuclear-powered airplane for a few days, with food and accommodation on the airplane, which is a great test for pilots.
Finally, the technical guarantee is also very troublesome. When the nuclear power is turned on, I am afraid that it is not easy to shut down, which means that the nuclear reactor is always running whether the aircraft is flying or not. To maintain such a dangerous power source at all times, not to mention the fear of security personnel, the maintenance cost is also very high. Once an accident occurs, the consequences are even more disastrous.
Therefore, the development of nuclear-powered aircraft is obviously not a good idea. But perhaps nuclear power can be used in spacecraft in the future, and it is a possible development direction to travel in the universe for decades without worrying about power problems.
