The singleaisle narrow body airliner(SANBA) is a type of passenger aircraft which is the most widely used, the largest number and the largest market demand. The product development of SANBA is active, and upgrading is quick. Technologies of SANBA are highly complicated and with significant driving effect. The development and design of SANBA is of great economic and technical significance. Firstly, the concept of SANBA was introduced, the features and classifications of SANBA were summarized and analyzed based on the technical parameters and characteristics of typical aircraft. According to the number of passengers/seats and range parameters, narrowbody aircraft was divided into three categories. Then the development of SANBA products and technologies were analyzed, the development history of major aircraft products since the 1960s were reviewed. This paper summarizes and analyzes the characteristics of SANBA and the ways of continuous improvement and serialization development. Finally, the paper analyzes the market situation of SANBA in the world, and reveals the market demand of SANBA, product production and sales data statistics, current market characteristics, and future market prospects.
