Reduction of wildlife on airfields through turfgrass selection
Aircraft collisions with wildlife are a major safety and economic concern for the aviation industry. Birdstrikes in particular are increasing due to rises in both the number of aircraft flights and the populations of several of the most hazardous bird species in North America. Traditional avian …

Bird Strike Risk Assessment for United States Air Force Airfields and Aircraft
… calculated for USAF aircraft and selected USAF airfields. Bomber aircraft had the highest strike rate; these aircraft frequently fly long missions at low altitudes where they are likely to encounter birds. Logistic regression analyses estimated odds of occurrence for damaging bird strikes during …

Automated Method for Airfield Pavement Condition Index Determination
… attached to automobiles, the characteristics of airfields and their pavements have prompted research into the use of drones as a flexible, and low cost solution for automating aspects of the inspection process. As one of the largest owners and operators of airfield pavement across the globe, the …

Aircraft Bird Strike Risk Prediction Using Machine Learning and Analytic Hierarchy Process
… strike data from four geographically diverse airfields served as the target risk variable, categorized as low, moderate, or severe based on Department of the Air Force risk models. The ensemble model, which combines the LSTM-RNN and XGBoost regression algorithms, yielded the most accurate …

Epoxy-Based, Rapid Setting Polymer Concretes for use in Military Airfield Repairs
When damaged, military airfields must be repaired quickly so that flying operations can resume. Due to their rapid-setting and high-strength properties, epoxy-based polymer concretes (PC) may provide a good alternative to the portland cement concrete (PCC) rapid repair mixes currently used by the …
