A Simulation of the Impacts of Climate Change on Civil Aircraft Takeoff Performance
… and headwind speed are major determinants of takeoff performance, and their sensitivity to global warming carries potential operational and economic implications for the commercial air transport industry. Previous archival and prospective research observed a weakening in headwind strength and …

Reduced fan noise radiation from a supersonic inlet
… The experiments were conducted at simulated aircraft takeoff engine speeds under static conditions. Steady-state measurements of the inlet flow field were made along with far field acoustic measurements of the fan noise. The results show the new door geometry is successful in reducing …

An evaluation of noise reduction strategies at large commercial airports in the United States: A policy analysis and framework classification
<p>Noise pollution from aircraft, specifically in the vicinity of airports as aircraft takeoff and land, is a problem that has been shown to have negative impacts on the welfare of humans, animals, and the surrounding environment. The problem may only become worse as air travel increases for cargo …

Performance scaling of a novel Modular Hybrid Propulsion System for aircraft flight performance flexibility and enhancement
… has the potential to enable a step-change in aircraft performance and flexibility over traditional carbon-fuel propulsion systems. The MHPS describes a hybrid propulsion system where the electrical components are interchangeable on a mission-to-mission basis. Scale-agnostic performance …

A decision problem involving the introduction of RTOL aircraft into commercial air transportation systems
… the feasibility of introducing a reduced takeoff and landing (RTOL) aircraft into the national aviation system. In considering this problem, a multiple criteria decision model based on the responses of airline executives was developed to describe the RTOL utilization problem. The exact …

A photogrammetric method for measuring transient frost surface roughness.
Cold-soaked fuel frost (CSFF) is a form of aircraft wing contamination that results in aerodynamic degradation. Unless a certification exemption for a specific aircraft model is provided by the FAA, an operator of an aircraft is not allowed to takeoff with CSFF on aircraft wing surfaces. To assist …
