Investigation of Propeller and Airframe Interaction on UAV
In this article, within the framework of the project “ Development of multi-purpose fixed-wing drone based on innovative solutions and the creation of necessary competencies”, our task was to examine a propulsion system mounted on an unmanned fixed-wing aircraft. We started the research by evaluating the results of the wind tunnel measurement. From the measurement data, we determined the characteristic curves of the propulsion system installed on the aircraft. We estimated the aerodynamic characteristics of the aircraft using the XFLR5 program. The operating conditions of the propeller in horizontal flight were determined from the results. It was found that the propeller fit is adequate at stall speed, but less than optimal at cruising speed.

A vizsgálatot a szélcsatornamérés eredményeinek kiértékelésével kezdtük. A mérési adatokból meghatároztuk a repülőgépre szerelt hajtásrendszer karakterisztikus görbéit. Megbecsültük a repülőgép aerodinamikai jellemzőit XFLR5 program segítségével. Az eredményekből meghatároztuk a légcsavar üzemállapotait vízszintes repülésben. Megállapítottuk, hogy a légcsavar illesztése átesési sebességen megfelelő, utazó sebességen azonban elmarad az optimálistól.

In recent years, the popularity of unmanned aircraft has increased significantly due to the fact that their possibilities of use are extremely wide. In connection with the criminal liability for the lawful use of drones, two criminal offences come into account. If open surveillance or recording takes place, civil sanctions for violation of personality rights may be applied, and if this unauthorised data processing causing significant harm to interests as a result, an offence of misuse of personal data pursuant to Section 219 (1) of the Criminal Code may be established. Secret surveillance is subject to the comprehensive facts of illegal data acquisition (Section 422 (1) (b) of the Criminal Code).

The UAVs Path Planning Challenges and Possible Solutions

These problems include the Point Vehicle problem or the Jogger’s Problem. I am going to present the state-of-art path planning algorithms and solutions like Visible Graph or A*.

The question often arises: What is the maximum distance of the UAV from the remote pilot during a VLOS operation? The answer is complex, and no specific numerical value is assigned, as it can be determined by considering a combination of factors. Unfortunately, the oft-mentioned rule of thumb of 1 km cannot be applied in all cases. In some cases, 1 km is the absolute maximum. However, it should be taken into account that the operation can become a BVLOS operation even a few times at a distance of 100 m, even if landmarks or other factors do not obstruct the visibility of the UAV.
" ["hu_HU"]=> string(715) "Sokszor felmerül a kérdés, hogy a látótávolságon belüli üzemben (VLOS) végrehajtott művelet során mekkora lehet az UAV maximális eltávolodása a távpilótától. A válasz összetett, és nincs konkrét számérték hozzárendelve, ugyanis több tényező együttes figyelembevételével lehet ezt megállapítani. A sokszor említett 1 km-esökölszabály sajnos nem alkalmazható teljeskörűen, minden esetre. Bizonyos esetekben az 1 km jelenti az abszolút maximumot, de figyelembe kell venni, hogy akár már néhány 100 m-eseltávolodás esetén is kikerülhet a művelet a VLOS-ból, még akkor is, ha az UAV-ravaló rálátást tereptárgyak vagy egyéb tényezők nem akadályozzák.

The functional integrity of brain perfusion and oxygen transport profoundly determines mental performance during military flight missions and spaceflight. Presently, at the selection phase of pilot candidates, there are no screening methods to evaluate cerebral circulation and its autonomous regulation (AR), meanwhile the pilot information processing capacity could be insufficient in dangerous flight situations with high mental workload or during high “head-to-foot” G loads. On-board ISS (International Space Station) and during deep-space missions circulatory changes can be evolved in the opposite direction due to the microgravity: blood shift toward the head-neck region can increase ICP (Intracranial Pressure) and tenfold increase of carbon-dioxide concentration can provoke complaints and disturbances in eye and brain blood circulation (Space Associated Neuro-Ocular Syndrome – SANS). The alteration of brain perfusion dynamics and oxygen utilisation was investigated on the head-down tilting table (HDT) test and in the hypobaric (low-pressure) chamber. We registered the brain regional pulse wave changes by the bioimpedance (Rheoencephalography – REG) on 19 volunteers in rest and after the breath-holding manoeuvre. We found that during the head-down tilt (HDT) position, the amplitude of the second peak of the REG pulse wave increased, like the ICP pulse wave, being an unfavourable sign for intracranial pressure increase in clinical cases. Manual readings resulted in significant differences during HDT between the female (P = 0.0007) and male (P < 0.0001) groups. With automated analysis, the increase in REG P2 wave was significant, and the ratio was 4/5 (80%) for women and 10/14 (71%) for men. The newly written automatic program script was able to detect this in 92% of the cases. The calculated values detected the state of cerebral circulatory autoregulation and the identity between the male and female groups. Based on this result and previous REG correlation studies, it can be concluded that REG could be used to monitor fighter pilots, astronauts, and neurocritical care patients in real-time as emergency alert in the transitory cessation of brain perfusion.

as an Active Surge Control
Centrifugal compressors are widely used throughout various industrial applications, including many safety-critical fields like aircraft engines. Thus, the enhancement of stable operational range is essential, which often requires active surge control methods. This includes state-of-the-art digital electronic measurement system to detect the onset of surge, which is a phenomenon that arises under extreme operational conditions and can lead to either negatively influenced behaviour or even the destruction of the compressor hardware in the case of uncontrolled conditions. Therefore, a strong emphasis must be given to observe impending surge and, if possible, to include an active system that can prevent undesired operational situations. Amongst many passive and active possibilities of surge control, Blade Load Distribution Control (BLDC) can be considered as a method, which creates acceptable influence on instabilities with a minor efficiency loss, consequently, could be applied as an active surge suppression system. The aim of this paper is to investigate feasible solutions on an existing centrifugal compressor test bench, which would enable to examine the theoretical solutions for blade load distribution control.

The triumphal march of helicopters can be traced back to the beginning of the 20th century. Although the technology – in both the literal and figurative sense of the world – was just spreading its wings at the time, the versatility and countless possibilities of use and application foretold the future success of the new aircraft. As time progressed, more modern types appeared one after the other, which became more and more efficient, stronger, faster and, most importantly, more and more safe.

A kor előrehaladtával sorra jelentek meg a korszerűbb típusok, amelyek egyre hatékonyabbak, erősebbek, gyorsabbak, és ami a fő, egyre biztonságosabbak lettek.

The development of unmanned aviation worldwide is on a massive scale. The number of reported flights now equals the number of flights by manned aircraft, and the trend is increasing. These flights should have some kind of time frame so that everyone can reach their destination safely. This requires a regulatory framework, both at international and domestic level, in which the aerospace industry can flourish as effectively as possible. In this publication, the author describes how this drone legislation has been envisioned in international law.

A bejelentett repülések száma mára vetekszik az ember által vezetett légi járművekkel történő repülések számával, és egyre inkább növekvő tendenciát mutat. Ezeknek a repüléseknek valamiféle keretet kell szabni, hogy mindenki épségben érhessen az úti céljához. Ehhez mind nemzetközi, mind pedig hazai szinten olyan jogszabályi kereteket kell felállítani, amelyben a lehető leghatékonyabban tud kiteljesedni a repülőipar. Ebben a publikációban a szerző bemutatja, hogy a dróntörvénykezést hogyan képzelték el a nemzetközi szabályozásban.

The DJI Dock 2 “drone in a box” is an enhanced version of the previous Dock 1 solution, where a more sophisticated, agile, mobile, lightweight and efficient product has been introduced to improve and meet the needs of reliable, fully autonomous drone operations even at an extended range. The latest advances in technology will enable the organisation, planning and execution of fully automated flight operations with drones, even beyond visual range. There are many missions and tasks that were previously dangerous to perform with human resources because it was too risky or did not provide an efficient and satisfactory solution for the control, guarding, protection or continuous surveillance of sites important for the operation of public bodies, sectors of the national economy or for guaranteeing the safety of the population. Now these problems can be adequately addressed with the DJI Dock 2 and its accessories, as it can be used for drone-powered patrols and guarded tours around protected areas.
