Analysis of the Transmissibility of Induced Vibration in Solid Propellant Rocket Motors during Transport

Abstract: The choice of packaging for the transport of sensitive cargoes can influence the propagation of vibrations produced by the vehicles and the roads used during transport operations. This article presents a study of the transmissibility of vibrations in the phases of terrestrial and air transport of a rocket engine and its parts. During measurements, the parameters were monitored at intervals of five minutes

Classification and Communication of Aviation Related Space Weather Radiation Events

Abstract: Space Weather impacts on the radiation field at aviation altitudes have been a matter of concern and discussion for many years. This situation has led to a growing demand for corresponding highquality information in the aviation industry. As a consequence, the Space Weather D-scale was introduced to provide aviation users and the interested public with relevant information about the development

From Human Behavior to Human Factor in Aerospace, Astronautics and Space Operations

Abstract: On ground, in the air or in space, men and women are actively involved in tasks achievement for the success of allotted missions. Their actions and interactions for planning, conceiving, managing, designing, building, testing, controlling, regulating or adapting are expressed through human behavior and operated by considering human factor. To promote further advances on manned missions

Influence of Sleep Disorders and Fatigue over Aircrew

Abstract: The performance of aircrew is subject to multiple factors that may interfere with human alertness, cognitive functions, and the ability to make tough decisions. The workload and flight,routines of aircrew make them subject to sleep disorders and excessive fatigue that may compromise their dexterity and, consequently, their life quality and the safe and secure aircraft operation.

No Sky for Old Men? Cognitive and Psychomotor Factors of Licensing 60+ Pilots for Single-Pilot Aircrafts

Abstract: A practical need of evidence-based criteria for assessing individual permission for piloting single,pilot aircrafts after 60 years was an inspiration to perform research and formulate a guideline,for psychological examination. Due to lack of empirical data from active 60+ pilots we analysed,cognitive, intellectual and psychomotor performance of over 3000 professional drivers aged 18-76,years

Effect of Modafinil on Changes in Tolerance to +Gz Induced by Total Sleep Deprivation

Abstract: Straining G level tolerance was measured of 45 healthy, males (20-22 years) in a baseline (non sleepdeprived) state and after 32 hours of Total Sleep Deprivation (TSD). Oral temperature (TOral), heart rate (HR) and mean arterial pressure (MAP) were also recorded. Stanford Sleepiness Scale(SSS) was used to score subjective perception of sleepiness/alertness. During TSD, the participants were randomised to

Evaluation of Mood and Anxiety in Pilots Undergoing Simulated Gravitational Pooling of Blood in the Lower Part of the Body

Abstract: Introduction: The main aim of the study was to assess mood and anxiety level in military pilots and cadets undergoing examination using the lower body negative pressure (LBNP) method. There can be found many research works on subjects’ well-being during MRI procedures in the literature. Similarly to MRI tube, an LBNP device requires a fixed position of the body and limits the ability

Amplitude Modulation of Wind Turbine Noise

Abstract: Due to swish and thump amplitude modulation, the noise of wind turbines cause more annoyance than other environmental noise of the same average level. The wind shear accounts for the thump modulation (van den Berg effect). Making use of the wind speed measurements at the hub height, as well as at the top and the bottom of the rotor disc

Altitude Controlling and Trajectory Tracking of Quadrotor UAV by using Model Predictive Control

Abstract: In this paper, Model Predictive Controller (MPC) scheme is proposed to stabilize the desired altitude and attitude of the Quad-rotor-Unmanned Aerial Vehicle (Q-UAV). The proposed control strategy uses control input as a reference which is utilized to track the referred trajectory, such that

Wind Turbine as a Point Source of Noise

Abstract: Practically the sound energy of a wind turbine is produced by the blades, a few tens of meters long. Despite this the noise prediction models assume that the sound energy is emitted by a point source at the hub height. The replacement of the rotor disc – the real source by a point source brings about an error in the predicted sound level.
