A Centennial Review of Sub-sonic Transport Aircraft
From Wright Brothers 1903 to present day 2003, aeronautical technology has made a profound progress. This paper demonstrates the outcome of this progress in weight, wing area, and engine thrust in three categories of transport aircraft of short to long range, regional jets, and turbo-prop commuter aircraft. Also the paper includes those aircraft with distinct jump in aeronautical technology. Fe...

Distributed propulsion and lightweight structures on transport aircraft pose a significant opportunity to meet next generation aircraft requirements including reduced fuel burn/emissions and enhanced takeoff/landing performance. The objective of this research is to conduct multidisciplinary design analysis and optimization to demonstrate a novel concept of flexible wing shaping aircraft using d...
متن کاملEnhancing Aircraft Performance Through Flight / Propulsion System Integration
Aircraft performance enhancement by integrating the propulsion control system with the primary flight control system is demonstrated through two nonlinear flight control design examples. In the first example, high performance aircraft turning performance improvement using engine thrust modulation is demonstrated. In the second example, the flight propulsion system integration is used to achieve...
متن کاملDistributed Propulsion Aircraft with Aeroelastic Wing Shaping Control for Improved Aerodynamic Efficiency
This study presents an aeroelastic wing shaping control concept for distributed propulsion aircraft. By leveraging wing flexibility, wing-mounted distributed propulsion can be used to re-twist wing shapes in-flight to improve aerodynamic efficiency. A multidisciplinary approach is used to develop an aero-propulsive-elastic model of a highly flexible wing distributed propulsion transport aircraf...

متن کاملDistributed Propulsion Vehicles
Since the introduction of large jet-powered transport aircraft, the majority of these vehicles have been designed by placing thrust-generating engines either under the wings or on the fuselage to minimize aerodynamic interactions on the vehicle operation. However, advances in computational and experimental tools along with new technologies in materials, structures, and aircraft controls, etc. a...
