Sonunda, Microsoft Flight Sim 2024'e dinozorlar resmi olarak ekleniyor. Bu haber her ne kadar heyecan verici gibi görünse de, benim için pek bir anlam ifade etmiyor. Yani evet, dinozorlar var olacak ve bu parklar, adalar etrafında uçmak mümkün olacak. Ama ne kadar ilginç ki? Jurassic World'deki o ünlü adalarda uçmak belki de bir nebze eğlenceli olabilir, ama ne kadar süre? Uçuş simülatörü zaten bir yerde sıkıcı değil mi? Uçak kullanmak, manzaraları görmek, tamam ama dinozorlarla dolu bir dünyada uçmak bana pek bir şey ifade etmiyor. Belki de dinozorlar biraz daha hayat katacak ama yine de o kadar heyecan duymuyorum. Her neyse, sanırım bu özellik, Microsoft Flight Sim 2024'ü biraz daha dikkat çekici hale getirecek. Ama hâlâ bu kadar uzun bir bekleyişin ardından, çok fazla beklentiye girmemek lazım. Uçakları uçurmak ve dinozorları görmek harika olabilir ama sonunda yine de bir simülatör. Hadi bakalım, bakalım dinozorlar ne kadar eğlenceli olacak. Ama şimdilik, biraz sıkıcı bir bekleyiş var gibi. İşte böyle. #MicrosoftFlightSim2024 #Dinozorlar #OyunHaberleri #JurassicWorld #Simülatör

Srbija uhvaćena u izvozu streljiva za Izrael; Vučić: ‘Ne pada mi na pamet da kažem šta je uzletjelo‘ Srbija je u prvoj polovici 2025. u Izrael izvezla streljivo ukupne vrijednosti oko 55,5 milijuna eura, što je više nego tijekom cijele 2024. kada je izvoz dosegnuo do tada rekordnih 47,9 milijuna, objavila je u utorak Balkanska istraživačka mreža (BIRN) na temelju zajedničkog istraživanja s izraelskim listom Haaretz. Među kupcima streljiva je moćna izraelska tvrtka koju je izvjestiteljica UN-a o stanju ljudskih prava na okupiranom palestinskom teritoriju Francesca Albanese u svom izvješću označila kao "profitera genocida koji traje" u Gazi, otkrivaju BIRN i Haaretz. U tekstu objavljenom na portalu BIRN-a navodi se da se srbijanski predsjednik Aleksandar Vučić 6. lipnja, u intervjuu za Jerusalem Post, "iznenađujuće pohvalio da je Srbija jedina zemlja u Europi koja prodaje streljivo Izraelu". Međutim, par tjedana poslije, navodi BIRN, 23. lipnja, na pitanje novinara je li Srbija izabrala stranu u izraelsko-iranskom sukobu time što izvozi streljivo u Izrael, Vučić je rekao da je država obustavila izvor oružja i streljiva. "Sada ne izvozimo ništa. Sada smo zaustavili sve i moraju biti posebne odluke, ukoliko će nešto ići", rekao je tada Vučić. VUČIĆ DRUMOM, IZRAELSKI AVION ZRAKOM Istog dana, samo nekoliko sati nakon što je Vučić proglasio moratorij na izvoz, na aerodrom "Nikola Tesla" sletio je izraelski teretni zrakoplov Boeing 747, a idućeg dana poletio je ka izraelskoj zrakoplovnoj bazi Nevatim, navodi se u istraživanju, prema podacima sa stranice Flightradar24. Na pitanje o letu tog zrakoplova kasnije tog dana, Vučić je uzvratio: "Ne pada mi na pamet da kažem šta je uzletjelo, a šta je sletilo". Portal BIRN navodi da je do tih podataka došao iz uvida u carinske dokumente, dodajući da se datumi izvoza iz prve polovice 2025. poklapaju sa 16 izraelskih letova iz Beograda prema zračnoj bazi Nevatim, koje su novinari identificirali na nekoliko mrežnih stranica koji uživo prate avionske letove. Osim državne tvrtke koja se bavi prodajom naoružanja i vojne opreme "Jugoimport SDPR", još pet srpskih privatnih kompanija izvozilo je streljivo ili oružje u Izrael tijekom posljednje dvije godine, objavio je prethodno beogradski tjednik Radar, dok BIRN i Haaretz otkrivaju da su dvije od tih pet tvrtki – "Edepro" i "Romax Trade", ove godine izvozile streljivo dvama poznatim izraelskim sigurnosnim kompanijama koje među svojim klijentima imaju Izraelske obrambene snage (IDF). https://slobodnadalmacija.hr/vijesti/regija/srbija-uhvacena-u-izvozu-streljiva-za-izrael-vucic-ne-pada-mi-na-pamet-da-kazem-sta-je-uzletjelo-1494406

Patruglia delle linee elettriche: l'occhio del grid nel cielo. Oggi, mi sono trovato a pensare a come monitorare il traffico aereo con gli aggregatori ADS-B come FlightAware e ADS-B Exchange. Sicuramente, ci sono percorsi di volo interessanti, ma non so quanto questo possa essere davvero emozionante. Credo che ci sia una certa monotonia nel seguire il traffico aereo, come se stessi perdendo tempo a guardare aerei che passano senza uno scopo preciso. Le pattuglie delle linee elettriche, beh, sembrano essere un argomento simile. C'è qualcosa di affascinante nel vedere queste linee che si estendono nel nulla, ma alla fine, è solo un altro modo di osservare il mondo da un angolo diverso. La realtà è che la maggior parte di noi non ha davvero voglia di alzarsi dal divano e dare un'occhiata seria a tutto ciò. Certo, ci sono alcuni che trovano piacere nel seguire il comportamento del traffico aereo. Ma per il resto di noi, è solo un altro aspetto della vita moderna che ci passa accanto senza che ci interessi troppo. In un certo senso, potrebbe sembrare che le pattuglie delle linee elettriche siano qui per mantenere il sistema in funzione, ma chi si preoccupa davvero? Tanto vale restare lì, a osservare il soffitto o il video della serie che stiamo seguendo. In conclusione, mentre ci sono quelli che amano monitorare ogni dettaglio del mondo aereo e delle linee elettriche, io mi sento più incline a godermi il momento, indipendentemente da quanto possa sembrare noioso. #PatrugliaLineeElettriche #TrafficoAereo #ADS_B #VitaModerna #Noia

A Chinese tech company called Leishen Intelligent System Co., Ltd., known for its LiDAR systems, has recently introduced a bug-zapping laser device designed specifically to combat mosquitoes. The system uses AI and laser tracking to identify mosquitoes mid-flight and eliminate them using precision laser beams. The device has been showcased at various tech expos in China and has gained attention for its ability to neutralize up to 30 mosquitoes per second, based on controlled environment demonstrations. The laser weapon works by using a combination of sensors, real-time tracking, and a low-power laser that is safe for humans and pets but lethal to small insects. The aim is to reduce mosquito populations without relying on chemical sprays or harmful toxins, which often have environmental side effects. This development aligns with increasing efforts to control mosquito-borne diseases like dengue, malaria, and Zika, especially in high-risk regions.

In 1988, a Boeing 737 suffered a loss of pressure during flight, which caused a large piece of the upper part of the plane to break off The pilot, who was desperately trying to control the plane, managed to land it safely 13 minutes later. A flight attendant who needed to move due to her work duties was sucked out of the cabin, and was the only casualty during the entire episode. Because the plane flew in incredible conditions and landed successfully, the story was made into a TV movie, "Flight 243: Emergency Landing".

#mewton #physics #flight The Physics of Flight: Applying Newton's Laws and Bernoulli's Theorem to Aircraft Aerodynamics Introduction The ability of massive metal machines weighing hundreds of tons to defy gravity and soar through the air is one of the most impressive technological achievements of the modern era. While the Wright brothers' first powered flight in 1903 lasted only 12 seconds and covered 120 feet, today's commercial airliners can stay aloft for over 17 hours and travel nearly 10,000 miles nonstop. This remarkable progress has been made possible through advancements in aeronautical engineering, which is fundamentally grounded in classical physics principles like Newton's laws of motion and Bernoulli's theorem. This essay will examine in depth how Newton's laws and Bernoulli's theorem combine to explain the principles of aircraft flight. We will analyze the role of each law in generating lift, explore the importance of airfoil design, and investigate other factors affecting aerodynamic performance. By integrating theoretical concepts with experimental data and real-world examples, we aim to provide a comprehensive understanding of the complex physics behind modern aviation. Newton's Laws and Aircraft Lift Newton's First Law: Inertia Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the context of aviation, this law explains why an aircraft in level flight tends to remain in steady motion. The various forces acting on the aircraft (thrust, drag, lift, and weight) are in equilibrium, allowing it to maintain a constant velocity (Beard & McLain, 2012). Newton's Second Law: Force and Acceleration The second law, F = ma, relates force, mass, and acceleration. This fundamental equation governs the motion of an aircraft in flight. When the thrust produced by engines exceeds the drag force, the aircraft accelerates. Similarly, when lift exceeds weight, the aircraft climbs. The precise control of these forces allows pilots to maneuver aircraft with remarkable precision (Anderson, 2016). Newton's Third Law: Action and Reaction Newton's third law, which states that for every action there is an equal and opposite reaction, is perhaps the most crucial in understanding lift generation. As an aircraft's wings move through the air, they deflect air downwards. The equal and opposite reaction to this downward deflection of air is an upward force on the wings - lift. This can be visualized using the concept of a control volume around the wing: ^ Lift | -->|--> Airflow | v Downwash The rate of downward momentum imparted to the air is equal to the upward force (lift) experienced by the wing. This principle is often referred to as the "momentum theory" of lift (Smith, 1992). Bernoulli's Theorem and Airfoil Design While Newton's laws provide a fundamental explanation for lift, Bernoulli's theorem offers additional insights, particularly in understanding the pressure distribution around an airfoil. Bernoulli's Equation Bernoulli's equation states that in steady, inviscid, incompressible flow, the total pressure along a streamline remains constant: P + 1/2 ρv² + ρgh = constant Where: Application to Airfoils The key to understanding how Bernoulli's theorem applies to airfoils lies in the shape of the wing. A typical airfoil has a curved upper surface (extrados) and a flatter lower surface (intrados): Extrados ____________ / \ / \ /________________\ Intrados As air flows over the wing, it must travel a greater distance over the curved upper surface than the flatter lower surface in the same amount of time. This results in higher velocity over the upper surface. According to Bernoulli's equation, this higher velocity corresponds to lower static pressure (Kundu et al., 2016). The pressure difference between the lower and upper surfaces of the wing creates a net upward force - lift. This explanation is often called the "equal transit time" theory, though it's important to note that in reality, air passing over the top of the wing actually reaches the trailing edge before air passing under the wing. Integration of Newton's Laws and Bernoulli's Theorem While Newton's laws and Bernoulli's theorem are often presented as competing explanations for lift, they are in fact complementary. Bernoulli's theorem helps explain the pressure distribution around the airfoil, while Newton's laws account for the reaction force from deflecting the airflow. Modern computational fluid dynamics (CFD) simulations have shown that both effects contribute to lift generation. The relative importance of each can vary depending on factors such as angle of attack, airfoil shape, and flight speed (McLean, 2012). Other Factors Affecting Aerodynamic Performance Viscosity and Boundary Layers Real fluids, unlike those in idealized models, have viscosity. This leads to the formation of boundary layers - thin regions of fluid close to the surface where viscous forces are significant. The behavior of these boundary layers, including whether they remain laminar or become turbulent, significantly affects drag and lift (Schlichting & Gersten, 2016). Vortex Formation As an airfoil generates lift, it also produces vortices, particularly at the wing tips. These wing tip vortices are a major source of induced drag. Understanding and mitigating their effects is crucial for improving aircraft efficiency (Auld & Srinivas, 2017). Wing ____________ | | | | Wingtip Vortex | | / |____________|/ \ \ Angle of Attack The angle of attack - the angle between the chord line of an airfoil and the direction of the oncoming air flow - plays a critical role in lift generation. As the angle of attack increases, lift generally increases up to a critical angle. Beyond this point, the airflow separates from the upper surface of the wing, leading to a sudden loss of lift known as stall (Anderson, 2016). Experimental Data and Real-World Applications Theoretical principles are validated and refined through extensive wind tunnel testing and flight data analysis. For example, pressure distribution measurements on actual aircraft wings have confirmed the lower pressure on the upper surface predicted by Bernoulli's theorem. NASA's Advanced Subsonic Technology (AST) program conducted detailed studies on high-lift systems, providing valuable data on how various wing configurations affect lift and drag. These studies have led to the development of sophisticated multi-element airfoils used in modern aircraft (NASA, 2000). In practice, aircraft designers use a combination of theoretical models, computational simulations, and experimental data to optimize wing design. Factors such as cruise speed, required lift coefficient, and operational altitude all influence the final airfoil shape and overall wing configuration. Conclusion The principles of flight, grounded in Newton's laws and Bernoulli's theorem, represent a triumph of applied physics and engineering. By manipulating airflow to create pressure differentials and momentum changes, aircraft designers have enabled humans to soar through the skies with remarkable efficiency and safety. As we've seen, the generation of lift is a complex phenomenon involving multiple interacting factors. While simplified explanations can provide intuitive understanding, a truly comprehensive grasp of aerodynamics requires integrating various theoretical approaches with experimental data and real-world observations. Looking to the future, ongoing research in areas such as adaptive wing structures, laminar flow control, and advanced composite materials promises to further enhance aircraft performance and efficiency. As our understanding of aerodynamics continues to evolve, so too will our ability to push the boundaries of aviation technology. References Anderson, J. D. (2016).
