In 1971, a Swedish Air Force Saab AJ 37 Viggen crashed during a landing demonstration due to issues with its thrust reverser and yaw control mechanisms. The thrust reverser, designed for short landings, disrupted airflow over the tail fin, leading to significant yaw disturbances. Additionally, the yaw damping system and nose wheel steering did not function properly during reverse thrust, causing the aircraft to veer off the runway and collapse the main landing gear. Fortunately, the pilot surviv

What is behind Gripen's dispersed air base capabilities? The answer lies in the Gripen's canards, inherited from the Saab 37 Viggen. These canards provide increased lift at slower speeds during landings. The synergy between the canard and wind rudders is critical to Gripen's short takeoff and landing (STOL) capabilities, creating aerodynamic downforce that enhances the effectiveness of the brakes. | Saab India
