The utility model relates to a clogging for the dynamic and static pressure test of the front and rear cabin seats of an aircraft in the dynamic and static pressure air tightness test and the cockpit pressurization air tightness test, belonging to the field of aircraft instruments. A blockage for dynamic and static pressure test includes dynamic pressure blockage of front and rear cabin seats of aircraft and static pressure blockage of front and rear cabin seats of aircraft. The dynamic pressure blockage is used to seal the dynamic pressure joints. An external thread matching the dynamic pressure joints is arranged at one end of the dynamic pressure blockage. The static pressure blockage is used to seal the static pressure joints. The internal of the static pressure blockage is provided with a cavity and the static pressure joints are arranged on the cavity. Matched internal threads. The utility model has the following advantages: 1. The cockpit height differential gauge before and after cockpit height protection is not damaged by the cockpit pressurization pressure by using the dynamic and static pressure test plugging. 2. The airtightness test of aircraft hydrostatic system and cockpit pressurization airtightness test were completed efficiently, conveniently and quickly without disassembling the dynamic and static pressure joint of the front and rear cabin seats. 3. It meets the design technical requirements, and the dynamic and static pressure test plug can be used repeatedly. It is suitable for all models and has good popularization.
