FLIGHT DATA ACQUISITION AND RECORDING SYSTEM

2011-06-06
CURRENT
ARINC717-15
This document provides design guidance for the development and installation of a Digital Expandable Flight Data Acquisition and Recording System (DEFDARS) primarily intended for airline use. As such, this guidance will include specific requirements necessary to accommodate mandatory flight data recording and other flight data acquisition needs plus the requirements to ensure customer controlled interchangeability of equipment in a standard aircraft installation. The system capability was expanded to accommodate a data bus speed of 1024 words per second.

Frontal Crash Reconstruction Compared to Event Data Recorders in the Crash Investigation Sampling System Database and the Effect on Injury Risk Models

2023-07-17
2023-01-5043
This study compares statistical models for frontal crash injuries based on delta-v data reported by the vehicle event data recorder (EDR) with injury probability models based on delta-v reconstructed by Crash Investigation Sampling System (CISS) investigators. Injury probabilities and their follow-on use in advanced automatic crash notification (AACN) systems have traditionally been based on delta-v obtained through accident reconstruction of field crashes in the National Automotive Sampling System Crash Data System (NASS-CDS) database. Field delta-v from EDRs in the CISS database is an alternative source of information for crash injury probability modeling. In this study, frontal impact injury risk probabilities computed from EDR and reconstructed delta-v were compared. All data came from the years 2017–2021 of the CISS database, which contains EDR downloads and also reconstructed delta-v using crush measurements and NHTSA’s WinSmash software.

Effect of Cooling Airflow Intake Positioning on the Aerodynamics of a Simplified Battery Electric Road Vehicle

2024-04-09
2024-01-2521
The transition towards battery electric vehicles (BEVs) has increased the focus of vehicle manufacturers on energy efficiency. Ensuring adequate airflow through the heat exchanger is necessary to climatize the vehicle, at the cost of an increase in the aerodynamic drag. With lower cooling airflow requirements in BEVs during driving, the front air intakes could be made smaller and thus be placed with greater freedom. This paper explores the effects on exterior aerodynamics caused by securing a constant cooling airflow through intakes at various positions across the front of the vehicle. High-fidelity simulations were performed on a variation of the open-source AeroSUV model that is more representative of a BEV configuration. To focus on the exterior aerodynamic changes, and under the assumption that the cooling requirements would remain the same for a given driving condition, a constant mass flow boundary condition was defined at the cooling airflow inlets and outlets.
