modern fighters have basically eliminated the propellers, but in the field of early warning aircraft, propellers are still very popular, and the advantage of being on the ship is too obvious! There are two types of early warning aircraft: propeller and jet type. The propeller type is used because of its strong maneuverability and high flying flexibility, which is suitable for shipborne early warning aircraft. The

has been developing since the birth of the early warning aircraft, but the basic layout has not changed much, and the power is still the turboprop engine. The "old" turboprop engine + propeller is due to its particularity as a carrier-based early-warning aircraft, which not only ensures good take-off and landing performance, but also has excellent range performance. Compared with the currently commonly used turbofan engines, the biggest advantage of turboprop engines is fuel saving, and the airflow generated by the rotation of the propellers directly blows back to the wings, which has a natural lift effect, making the E-2 excellent in low speed performance, especially Suitable for shipborne takeoff and landing. The Air Police 600 early warning aircraft being developed by my country will also follow this layout.
U.S. carrier-borne early warning aircraft
is in fact fundamentally speaking, all propeller-powered aircraft are aimed at saving fuel, and propeller-powered aircraft, at low speeds, due to the high-speed airflow generated by the propeller Shooting the surface of the wing can improve the propulsion efficiency. Therefore, turbofan engines have already competed in the vast majority of markets today, but there are still many airplanes with good economy and low flying speed that still insist on using propeller engines as their power systems.

propeller-borne early warning system can detect long-distance low-altitude targets, and can also rely on altitude advantages, such as fleet lighthouses, which provide long-range air defense early warning. Compared with early-warning helicopters, fixed-wing early-warning aircraft, because of their size and space, have stronger flying time, range and speed, and electronic equipment. Therefore, US aircraft carriers have been specially equipped with a squadron of E-2 propeller early-warning aircraft to form early warning forces.
China is now building a domestically-made conventionally powered aircraft carrier, equipped with a catapult, and is worrying about which fixed-wing early warning aircraft will be on board. In the future, my country's domestically produced early warning aircraft will also be a propeller fixed-wing aircraft like the US E-2. It has a long time in the air, good low-speed performance, flexible response, and can quickly go around quickly after a failed landing. The carrier-based aircraft limits the empty weight and size of the early warning aircraft, but the propeller aircraft is not too worried about this. Its overall light weight, large pull at low speeds, and short take-off and landing distances are very suitable for boarding.
Chinese-made fixed-wing early warning aircraft
The Chinese Navy regards aircraft carriers as the main target of development in the new century, and fixed-wing carrier-based early warning aircraft is also a major development direction. The international community generally believes that my country’s future fixed-wing carrier-based early warning aircraft should also be a propeller aircraft. It uses a domestic turboprop engine with a large aspect ratio straight wing to obtain a higher lift-to-drag ratio and improve low altitude/low speed. Maneuverability and short-range takeoff and landing capabilities. In this way, it can be deployed not only on ejection aircraft carriers, but also on active aircraft carriers, further improving the combat capabilities of domestically-made aircraft carriers.
