Firstｌy the general situatlOn of thrust vector technique CTVThesearch and development is briefly accounted. Taking the development of the 4th generatlOn a1rcraftCF22/F1l9)and the third-haH generatlOn a1rcraft C CY-37 / AJI-37φ10) for example , this paper illustrates that TVT completely satisfies the tactical and technical reqUlrements of the 4th generatlOn a1rcraft and the third generatlOn a1rcraft is evolved to the third-haH generatlOn a1rcraft smce applying TVT , and fully demonstrates that TVT promoted development are pomted out and some advice about these technology's research in our natｉｏn 1S put forward.
