Transonic barriers are obstacles that aircraft need to overcome when traveling at high speeds close to the speed of sound. Synonyms for transonic barriers include sonic barriers, shock waves, sound barriers, and aerodynamic drag. These barriers can be challenging for aircraft designers as they can cause turbulence, vibration, and loss of control for the plane. To overcome these barriers, aircraft engineers use advanced technology and design techniques such as wing shaping, active flow control, and specialized materials that can withstand high temperatures and pressures. By overcoming transonic barriers, aircraft can travel faster, more efficiently, and with greater safety and stability.
