Dynamic Model of Aircraft Landing
Abstract
This manuscript presents a research method that will be used in the development process of avionics equipment. A special device predicting braking and take-off distances will help pilots and provide a complex increase of flight safety and decrease of some types of charges.
Education as a Basic Element of Improving Professional Important Qualities of Aviation Technical Maintenance Personnel
Abstract
In this article the importance of professional qualities, competence and their increase, directly dependent on the training of aviation technical maintenance personnel and determination the level of flight safety is covered. This publication analyses necessary training and requirements for aviation technical personnel involved in aircraft maintenance, as well as the requirements for aviation training organizations, defined as per Part-147, for such personnel preparation and training.
Experimental Proof of the Characteristics of Short-Range FM Radar Converted Signal Spectrum for a Smooth Surface
Abstract
This paper presents a natural experiment of the spectral processing of 4.3 GHz Frequency Modulated Continuous Wave Radar (FMCWR) converted signal. The FMCWR antennas are fixed above a smooth reflective surface. The converted signal spectrum is theoretically calculated and compared with the experimental data.
Human-In-The-Loop Remote Piloted Aerial Systems in the Environmental Monitoring
Abstract
Paper is related to development of flying robot system. The main objective is to mingle the professional backgrounds in three research directions: development of the aerial vehicle and localization, development of the tele-interaction framework and control system, development of the image fusion system and photogrammetry. Block diagrams give brief description of the systems and sub-systems under the proposed environmental system. Structure of the monitoring UAV adapted for the hand launch given.
Minimax Decision for the Reliability of Aircraft Fleet With and Without Information Exchange
Abstract
The scientific article addresses the dependence of aircraft fleet safety on the human factor. The article demonstrates the significance of information exchange concerning the open fatigue cracks, which is necessary to bring a new type of aircraft into operation. The article provides numerical examples obtained by means of the Monte Carlo method and considers the dependences of failure probability on various factors.
Research on the Propagation of AE Signals in Helicopter Structural Components
Abstract
The paper contains results of experimental research carried out helicopter bench. In order to create an attenuation chart for AE signal amplitude in helicopter fuselage, a number of experiments were performed on the frame and stringers, inside the fuselage. Later helicopter test bench was used to develop defect localization methodology of helicopter structure fatigue damage technical diagnostics. Analysing helicopter structural defects for different helicopters types it is concluded that the joint elements of helicopter tail boom are still exposed to fatigue crack formation. AE method shows highly effective results predicting fracture of helicopter joint elements.
The Effects of ACMI Flight Crew’s Long Term Outstation Hotel Stay on Accumulated Fatigue
Abstract
ACMI flight crews spend considerable time away from home on outstations. This manuscript suggests that long term stay carries its own considerations in regards to rest recovery with practical implications for Fatigue Risk Management. Four recovery factors are identified and are to be correlated with 28 crew behaviors. The end result might indicate improvement considerations for airline management organizing a long term contract with ACMI crews.
Evaluation of Management System Effectiveness in the Preparation of the Aircraft for Flight in Faulty Conditions
Abstract
Most flight delays in aviation enterprises are related to air traffic management and technical centers. This can happen for various reasons: untimely removal of defects, lack of spare parts, deficiencies in maintenance scheduling, etc. Another reason may be inefficient management in the system of preparing the aircraft for departure. The article suggests a possible option of such an assessment as well as the results obtained from the use of this methodology applied to a specific airline.
Evaluation of the Dynamic Characteristics of Aircraft during Landing in Crosswinds
Abstract
This article summarizes the results of aircraft lateral drift parameter estimation. The lateral drift of an aircraft may occur in extreme and dangerous situations when the aircraft lands in crosswind conditions. Such a situation is developing with great dynamics in a small period of time. Within seconds, the aircraft can drastically change the flight path or position. The article highlights the results obtained in a calculation made during the flight phase of the aircraft landing in crosswind.
