Urban turbojet fire vehicle

The invention provides an urban turbojet fire vehicle. The fire vehicle comprises a vehicle chassis. An ultrafine dry powder tank is arranged on the vehicle chassis. The ultrafine dry powder tank is connected with a nitrogen cylinder pressure vessel. The nitrogen cylinder pressure vessel is connected with a water pump system. The water pump system is connected with a liquid tank assembly. The liquid tank assembly is connected with a turbojet engine jet assembly. A jet device for fire extinguishing comprises a jet device. The jet device is connected with a central revolved body through a connection pipe. The urban turbojet fire vehicle has large jet power, can jet out a mass flow of 'tail gas-water spray-ultrafine dry powder' three-phase jet flow fire extinguishing agents in a short time, and has excellent capabilities of controlling fire behavior, extinguishing big fires and cooling fire scenes by aeration from the three-dimensional space. The urban turbojet fire vehicle plays an important role in extinguishi
