Hybrid-Electric Aircraft with Over-the-Wing Distributed Propulsion: Aerodynamic Performance and Conceptual Design

Recent developments in the field of hybrid-electric propulsion (HEP) have opened the door to a wide range of novel aircraft configurations with improved energy efficiency. These electrically-driven powertrains enable “distributed propulsion” configurations, in which the aerodynamic interaction between the propulsive devices and the airframe is...

Estimating aircraft drag polar using open flight surveillance data and a stochastic total energy model

In air traffic management research, aircraft performance models are often used to generate and analyze aircraft trajectories. Although a crucial part of the aircraft performance model, the aerodynamic property of aircraft is rarely available for public research purposes, as it is protected by aircraft manufacturers for commercial reasons. In...

OpenAP: An open-source aircraft performance model for air transportation studies and simulations

Air traffic simulations serve as common practice to evaluate different concepts and methods for air transportation studies. The aircraft performance model is a key element that supports these simulation-based studies. It is also an important component for simulation-independent studies, such as air traffic optimization and prediction studies....

A method for measuring take-off sjid landing performance of aircraft, using an inertial sensing system

The STALINS method for measuring take-off and landing trajectories is briefly described and results of flight tests made in 1978-80 are discussed. The method now meets the requirements to which it was designed, and a few improvements in the hardware and software are being finalized. The method is expected to be ready for operational use in the...
