The calibration of measurements of the four critical parameters that define an aircraft's air data state, the state of an aircraft relative to the air mass through which it is flying, is discussed. The parameters are altitude, airspeed, angle-of-attack, and angle-of-sideslip. The measurements are taken by external probes, usually located on the aircraft's forebody, and are affected by the aircraft contours, which tend to disturb the local airflow across the probes. It is shown that using an expert system to calibrate the data improves the process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

With the increasing amount of flight test data, the traditional single-thread technology has been unable to meet the needs of rapid processing of massive flight test data. In order to improve the efficiency of flight test data processing, the characteristics of flight test data processing are analyzed, and a parallel flight test data processing method is proposed. This method realizes two-level parallel processing of multi-link parallel and data frame analysis parallel of flight test data. The method is verified by actual data, and the results show that the efficiency of this method is significantly improved compared with the traditional single-thread data processing method.

Modern aircraft are capable of recording hundreds of parameters during flight. This fact not only facilitates the investigation of an accident or a serious incident, but also provides the opportunity to use the recorded data to predict future aircraft behavior. It is believed that, by analyzing the recorded data, one can identify precursors to hazardous behavior and develop procedures to mitigate the problems before they actually occur. Because of the enormous amount of data collected during each flight, it becomes necessary to identify the segments of data that contain useful information. The objective is to distinguish between typical data points, that are present in the majority of flights, and unusual data points that can be only found in a few flights. The distinction between typical and unusual data points is achieved by using classification procedures. In this dissertation, the application of classification procedures to flight data is investigated. It is proposed to use a Bayesian classifier that tries to identify the flight from which a particular data point came. If the flight from which the data point came is identified with a high level of confidence, then the conclusion that the data point is unusual within the investigated flights can be made.

The simulation accuracy of flight simulators directly affects training effectiveness. The current verification technologies and methods for flight performance simulation models of flight simulators rely on subjective evaluations based on pilots' experience. Therefore, this paper proposes a verification method for flight performance simulation models based on flight dynamics theory, designs dynamic simulation software, and adds a setting and display platform for control and flight quality, to conduct simulation experiments for verification. The research results show that the proposed verification method can effectively improve the quality and reliability of flight simulators, meet the objective verification needs of simulator developers for flight performance simulation models, and is of great significance for enhancing the effectiveness of flight simulators.

일반적으로 항공기 운동 모델의 충실도는 대상 항공기의 비행시험 결과와 비교하여 검증한다. 따라서 성능비교를 위한 기준 비행 데이터를 추출하는데, 각종 잡음이 포함된 방대한 양의 비행데이터를 처리하는 것은 많은 인력과 시간이 소요된다. 특히 회전익항공기는 축간 커플링 효과와 후류 간섭 효과 등으로 비선형성이 큰 특성을 가지고 있으며, 제자리 비행, 후진 비행 등의 다양한 기동을 수행하므로 비행 데이터를 처리하는 것이 복잡하다. 본 연구에서는 회전익항공기의 비행 데이터 처리 기준을 정의하고, 데이터마이닝 기법을 이용한 정적 및 동적 비행 데이터 자동 처리를 위한 절차와 방법을 제시한다. 최종적으로 비행데이터를 사용하여 제시한 방법을 검증한다.

Archeops is a balloon--borne experiment widely inspired by the Planck satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to measure the Cosmic Microwave Background (CMB) temperature anisotropies at high angular resolution (about 12 arcminutes) over a large fraction of the sky (around 30 %) in the millimetre and submillimetre range at 143, 217, 353 and 545 GHz. Further, the Archeops 353 GHz channel consists of three pairs of polarized sensitive bolometers designed to detect the polarized diffuse emission of Galactic dust. We present in this paper the update of the instrumental setup as well as the inflight performance for the last Archeops flight campaign in February 2002 from Kiruna (Sweden). We also describe the processing and analysis of the Archeops time ordered data for that campaign which lead to the measurement of the CMB anisotropies power spectrum in the multipole range l=10-700 (Benoit et al. 2003a, Tristram et al. 2005) and to the first measurement of the dust polarized emission at large angular scales and its polarized. We present maps of 30 % of the sky of the Galactic emission, including the Galactic plane, in the four Archeops channels at 143, 217, 353 and 545 GHz and maps of the CMB anisotropies at 143 and 217 GHz. These are the firstever available sub--degree resolution maps in the millimetre and submillimetre range of the large angular-scales Galactic dust diffuse emission and CMB temperature anisotropies respectively.

Flight trajectory data from Quick Access Recorders (QAR) is critical for ensuring flight safety and conducting performance analysis. However, the inherent uncertainties and noise present in this data necessitate the use of filtering techniques. The conventional Kalman filter, widely applied in civil aviation, exhibits limitations when addressing varying noise levels across different aircraft types and flight phases. This study addresses these challenges through a multistep approach. First, QAR data from Daocheng Yading Airport underwent preprocessing, including data cleaning, resampling, key field selection, and target trajectory extraction. Next, the Kalman filter’s adaptive capabilities were enhanced and applied specifically to three-dimensional trajectory data. Finally, a comparative analysis was conducted with the segmented noise matrix adjustment method. The results demonstrate that the adaptive Kalman filter effectively preserves essential data characteristics while streamlining the filtering process.

On November 16th, 2022, NASA launched the inaugural test flight of the Space Launch System (SLS) carrying the Orion capsule into a high orbit far beyond the Moon. The launch vehicle was instrumented with over three thousand flight instrumentation sensors, many of which monitored aerodynamic, acoustic, structural, and thermal environments. These data are intended contribute to the validation of experimental and numerical tools used to predict the design environments that the vehicle experiences during launch and ascent. Prior to launch, tests were performed at the SLS Systems Integration Laboratory (SIL) using flight-like avionics and on the integrated flight hardware of Artemis I at the Vehicle Assembly Building (VAB). The purpose of these tests was to characterize the data acquisition units (DAUs) used to record and telemeter flight data to ground stations in order to assure that flight test objectives can be achieved and to quantify the expected quality of the flight data. In addition, preflight assessment and development of tools and methods used to process and disseminate flight data at the Huntsville Operations Support Center (HOSC) were conducted and adjustments made with respect to DAU time synchronization prior to and after the flight. This paper summarizes these tests. Some aspects of the data postprocessing are discussed.

A pulse shape analysis framework is described, which was developed for n_TOF-Phase3, the third phase in the operation of the n_TOF facility at CERN. The most notable feature of this new framework is the adoption of generic pulse shape analysis routines, characterized by a minimal number of explicit assumptions about the nature of pulses. The aim of these routines is to be applicable to a wide variety of detectors, thus facilitating the introduction of the new detectors or types of detectors into the analysis framework. The operational details of the routines are suited to the specific requirements of particular detectors by adjusting the set of external input parameters. Pulse recognition, baseline calculation and the pulse shape fitting procedure are described. Special emphasis is put on their computational efficiency, since the most basic implementations of these conceptually simple methods are often computationally inefficient.

Under the NASA High-Alpha Technology Program the High Alpha Research Vehicle (HARV) was used to conduct flight tests of advanced control effectors, advanced control laws, and high-alpha design guidelines for future super-maneuverable fighters. The High-Alpha Research Vehicle is a pre-production F/A-18 airplane modified with a multi-axis thrust-vectoring system for augmented pitch and yaw control power and Actuated Nose Strakes for Enhanced Rolling (ANSER) to augment body-axis yaw control power. Flight testing at the Dryden Flight Research Center (DFRC) began in July 1995 and continued until May 1996. Flight data will be utilized to evaluate control law performance and aircraft dynamics, determine aircraft control and stability derivatives using parameter identification techniques, and validate design guidelines. To accomplish these purposes, essential flight data parameters were retrieved from the DFRC data system and stored on the Dynamics and Control Branch (DCB) computer complex at Langley. This report describes the multi-step task used to retrieve and process this data and documents the results of these tasks. Documentation includes software listings, flight information, maneuver information, time intervals for which data were retrieved, lists of data parameters and definitions, and example data plots.
