Simulation of Active Twist Rotor Blades using a Thermal Analogy Method in HMB3

: Recent commercial availability of smart materials has made high-frequency aerodynamic control a major research avenue for improving the efficiency, performance and ride quality of future rotorcraft. This approach is equally applicable to urban air mobility vehicles that demand lower noise and vibration levels than currently used helicopters. Smart materials are also of interest for military aircraft to reduce their noise signature, extend mission range and prolong the service life of components.

Hierarchical regression analysis of FOQA data to predict touchdown G for the Boeing 787

Hazards such as runway incursions, runway excursions, and in-flight loss of control, are appropriately well documented and emphasised within aviation safety literature given their catastrophic potential. Less well known, yet operationally significant, is Abnormal Runway Contact (ARC), a category of hazardous events encompassing tail strikes, nose-wheel-first contacts, and hard landings.

Advances in Unsteady Computational Aerodynamics with Separation: The 61st Lanchester Memorial Lecture

Advanced Air Mobility (AAM) is a burgeoning sector of the Aerospace industry exploring new design concepts from multi-passenger vehicles to small uncrewed autonomous systems for observations. These applications also expand operations into airspaces that were not previously engaged in commercial operations. The compounding of these with traditional aerospace vehicles and operations requires accuracy in aerodynamic analyses.

On the Performance of Highly Aggressive Inter Compressor Ducts

A major research focus of the Institute of Propulsion Technology at the German Aerospace Center (DLR) is increasing engine compressor efficiency. In this context, the intermediate compressor duct (ICD), which connects the low-pressure compressor (LPC) with the high-pressure compressor (HPC) in a civil jet engine is of eminent significance.

A simple model for the estimation of turbofan engine performance in all airborne phases of flight

The Aeronautical Journal December 2024 Vol 128 No 1330 Global air transport is a significant contributor to anthropogenic environmental impact. The use of kerosene for propulsion produces carbon dioxide and water vapour, both greenhouse gases, plus a mixture of nitric oxide and nitrogen dioxide that changes the levels of atmospheric, ozone and methane, also greenhouse gases.…

The Light Beyond the Clouds

Beyond the dark clouds there is light. Is this a topical description for the past, present and future of our industry? In the past, it was our ambition to travel fast and above the weather that inspired the development of the jet engine by its inventors, Sir Frank Whittle and Dr Hans von Ohain in the late 1930s and early 1940s.
