With the development of world's economy, energy shortage gradually appears. Resistance has a great influence on energy consumption. In other words, drag reduction means saving energy. Development of the drag reduction technology plays a very important role to improve the energy efficiency. Therefore, drag reduction technology of jet has become a hot research field. Drag reduction technology of jet is applied on the surface, so as to reduce surface friction resistance. Through analyzing the necessity of energy efficiency increase and jet drag reduction theory improvement, research progress of lateral jet flow technology and drag reduction technology of jet in the field of aircraft are reviewed. Besides, a main trend on the drag reduction technology of jet research is presented.
