Performance Improvement of the CRJ700 Aircraft Using Adaptive Winglets with Variable Twist Angle

Year: 2026

Type: article

Abstract: This study investigates the potential of adaptive winglets with variable twist angles to improve the aerodynamic and energy performance of the Bombardier CRJ700. CFD simulations conducted in Star-CCM+, validated with a level-D flight simulator at LARCASE, reveal that twist adaptation can significantly reduce drag. A trajectory-based performance analysis shows that, during climb, adaptive winglets can reduce fuel consumption and climb time by up to 1.24% and 1.82%, respectively, or an increase of the ground distance by up to 2.67%. In cruise, fuel savings reach up to 0.4%. These results highlight the effectiveness of adaptive winglets in enhancing regional jet efficiency.
