Opis:: In this paper, the results of an aircraft’s positioning in aviation during two flight tests are presented. The aircraft’s position was established using GPS data with a sample rate of 1 s in both experiments. The raw GPS data were collected by a Topcon Hiper Pro receiver, which was installed in the pilot’s cabin of a Cessna aircraft. The aircraft’s coordinates in the BLh geodetic frame were determined using the single point positioning (SPP) method in gLAB software. The mathematical algorithm for the aircraft’s coordinates are also described in the article. The typical standard deviations for the aircraft’s coordinates were less than 10 m in test I and less than 30 m in test II.

Opis:: This paper presents the results of studies on the determination of an aircraft’s trajectory and positioning accuracy. The PPP method was applied to determine the aircraft’s position in kinematic mode for code observations in the GPS system. Computations were executed in the “PPP_KINEMTIC” software, whose source code was written using the Scilab 5.3.2 platform. The PPP_KINEMTIC software allows for the latitude coordinate to be estimated with accuracy between 1 and 6 m, the longitude coordinate to be estimated with accuracy between 0.5 and 2.5 m, and the ellipsoidal height to be estimated with accuracy between 1 and 7 m. The average value of the MRSE term equals 5 m with a magnitude between 1 and 8.5 m. In the paper, general libraries of the PPP_KINEMTIC application were presented and the PPP method was characterized too.

Tytuł:: Planning the flight trajectory of a passenger aircraft with regards to the aspect of pollutants emission

Tematy:: aircraft

Opis:: One of the ways to reduce the adverse impact of aircraft on the environment is through the determination of the trajectory of the flight on a given route that leads to reducing fuel consumption and, consequently, emission of pollutants in jet engines exhausts. Planning a flight in terms of minimizing emissions or fuel consumption is a complex task and difficult to implement due to the conditions in which the aircraft travels, but it is possible though. It is necessary to take into account the limitations resulting from the organization of the airspace and the rules therein, as well as the current weather conditions. The weather is one of the main factors determining the amount of fuel consumed, the time and cost of a particular flight on a given route. In addition to the main parameters, such as pressure and air density, it is extremely important to determine the air temperature, as well as the wind speed and direction. The temperature affects the speed of sound, based on which it is possible to determine the Mach number for a plane flying with a given true air speed (TAS). The speed and direction of wind, on the other hand, affect the speed of the aircraft relative to the ground (velocity over ground, VOG), and thus the duration of its flight. The article describes how the developed model of emission of pollutants in the exhausts of jet bypass engines can be useful for determining the trajectory of an aircraft in its cruise phase due to the criterion of pollutants emissions minimization. An exemplary analysis was carried out for selected aircraft moving along the route adopted for the research. The analysis covered various cruising altitudes and various meteorological conditions (wind speed and direction). The obtained results are illustrated graphically and discussed.

Tytuł:: Minimum emission unconventional MAGLEV assisted take-off

Opis:: Among the most important problems faced by the air transport today there can be mentioned some negative influences of aircraft and airports on the environment and the increasing costs of air transport. One of the possibilities to improve the situation is to work out innovative solutions aimed at decreasing of the aircraft pollution and improving the transport effectiveness. Among the most innovative ideas is the use of magnetic levitation (MAGLEV) to aid the take-off and landing of the transport aircraft. The “Integrated Ground and on-Board system for Support of the Aircraft Safe Take-off and Landing” – GABRIEL, deals with radically new integration of the MAGLEV technology into the air transportation system that contains aircraft, airport, air traffic control, authority, logistic and operational support, maintenance, etc. GABRIEL idea includes operation of the aircraft without the conventional undercarriage system and using the ground based power and supporting systems for take-offs and landings. In case of using the GABRIEL system as a catapult, the aircraft on the track must be accelerated to the speed permitting to reach the altitude of 300 m or more. Such take-off and climb results in minimum noise and minimal emission of substances harmful for the environment. After reaching the altitude of 300 m, the aircraft may follow its flight with using different flight strategies. Different conditions of the unconventional take-off needs to shape other way the trajectory of the initial stage of the aircraft flight after the lift-off. The aim of the present work was to determine the optimal conditions of the lift-off and the optimal trajectory of the initial climb minimizing the emission. Simplified realization of the Ritz- Galerkin method was used in this work, which uses an approximate solution to boundary value problems for determining the optimal flight trajectory.

Opis:: The development and use of unmanned airborne systems are currently undergoing a huge transformation. This allows the development of computer technology, new materials for their construction. Reducing airborne funds would enable them to be widely used. This applies to not only military use but also mainly civil use, industrial and commercial use as well. This new use brings new challenges, including security, legislative, technical, social, and so forth. This paper focused on the possibility of having several Unmanned Aircraft Systems movement in urban areas. It contains the description of a philosophical proposal of flight corridors and flight trajectories in urban areas with the example of a small town.

Tytuł:: Sensitivity analysis for dynamic models of aerial munitions

Tematy:: aircraft

Opis:: While investigating dynamic properties of aerial bombs, both the analytical and experimental outcome often find their applications. Analysis of how a series of changes in flight parameters affect flight dynamics is probably one of the most essential efforts throughout this study. Numerical solutions of equations of motion deliver no information on the effect of changes in the aerial bomb’s design parameters on flight characteristics thereof. Therefore, the theory of sensitivity has been used in the paper to investigate the effect(s) of external disturbances, drop/release conditions and technical parameters on the aerial bomb’s range and flight path. Among other, the elements of the theory of sensitivity, equations of motion, numerical analysis of sensitivity of the bomb-describing mathematical model to changes in some selected parameters, numerical analysis of sensitivity of the bomb-describing mathematical model to changes in some selected parameters, analysis of the effect of changes in drop/release conditions on the aerial bomb’s flight path, analysis of the effect of changes in engineering (design) parameters of the aerial bomb on the trajectory thereof, effect of drop conditions on the aerial bomb’s range, effect of drop conditions on the side deflection of the aerial bomb’s trajectory are presented in the paper.
