🏋♀️ Weight is a key parameter in the #UAV sector: primarily to maximize flight endurance, and secondly because in several UAV configurations, the balance of the air vehicle can be affected when the manufacturer replace its engine by another one. ▶️ The #Trident100TD2 weighs 115 kg fully installed. This includes fluids, the turbocharging system, coolers, starter, single-pitch propeller, generator, engine mount, and all components after the firewall necessary for the engine to operate properly. 👉 This #weight can be optimized based on customer requirements. For instance, the generator depending of the electrical need, or the dual-stage turbocharging system—designed for high-altitude performance—could be replaced with a simpler single-stage system if your mission does not require extreme altitudes. This change would eliminate one turbo stage and its associated intercooler, reducing the overall weight. Everything is possible, just ask! 📱 Stay connected through the DANIELSON AIRCRAFT SYSTEMS page for all the exciting updates to come! ❓ Want to learn more? https://lnkd.in/dt7ZHbut or contact us! #UAVEngine #UAVEngines #DronePropulsion #UAV #MALEUAV #DroneTechnology #Aerospace #DefenseTech #DefenseIndustry #Aviation #DroneEngines #ISR #AviationInnovation #MilitaryTechnology #MilitaryAerospace

We are proud to present two groundbreaking advancements that are central to our A modular propulsion technology - our Cyclic Cooling technology and Propeller Adaptive Locking design. #industrial #uav Cyclic Cooling Technology Our Cyclic Cooling technology optimizes heat dissipation by keeping the heat dissipation channel unobstructed. This results in an 11% increase in flow velocity and volume, leading to a 9% reduction in temperature rise. Even when operating in hot environments, there is no need to use a larger size model. Propeller Adaptive Locking Design Traditional propeller clamps often have difficulty achieving the ideal locking force - locking too tight makes the propeller difficult to open, while locking too loose can cause dangerous vibrations or even eject the propeller completely. Our design can adaptively eliminate any gap that may occur over continuous operation, enhancing flight safety We invite you to explore our innovations and see how they can benefit your application：https://lnkd.in/gqTMmWj8 #drone #hot #environment

𝐀𝐢𝐫𝐜𝐫𝐚𝐟𝐭 𝐃𝐨𝐫𝐬𝐚𝐥 𝐅𝐢𝐧𝐬 Dorsal fin is a vertical surface extension on the back of the fuselage forward of the vertical tail with a leading edge sweep much larger than the leading edge sweep of the main vertical tail. Because of its higher aspect ratio and smaller sweep, the vertical tail has a steeper lift curve slop and produces rapidly increasing yawing moments at low sideslip angles. Unfortunately, it stalls at low angles. On the other hand, the dorsal fin, with it's low aspect ratio and large sweep, achieves higher sideslip angles before stalling by creating vortices that reattach the flow. In this way, it helps the aircraft retain directional stability in case it will ever experience high sideslip angles. To learn more about tail sizing, please have a look at this research paper https://lnkd.in/dFkvddDu Image source : https://lnkd.in/dVtPnni7 If you like this post, repost and share with your colleagues.

If the direction of rotation is not explicitly mentioned, there are a few ways to determine which propeller is rotating in which direction: 1. Look for the propeller's blade angle:- Typically, the leading edge of the propeller blade is angled slightly forward. If you can see the blades, check the angle of the leading edge. If it's angled forward, the propeller is likely rotating clockwise (from the perspective of the observer). 2. Check the propeller's hub or spinner:- Often, the hub or spinner (the central part of the propeller) will have an arrow or a marking indicating the direction of rotation. 3. Observe the propeller's movement:- If you can see the propeller moving, observe the direction of the blades' motion. If the blades are moving from top to bottom, it's likely rotating clockwise. If they're moving from bottom to top, it's likely rotating counterclockwise. 4. Consult the aircraft's documentation:- If you have access to the aircraft's manuals or documentation, check the specifications or diagrams for propeller rotation direction. 5. Assume standard convention:- In general, most aircraft propellers rotate clockwise (from the perspective of the observer) when viewed from the front. However, this is not always the case, so it's essential to verify the direction if possible. Keep in mind that some aircraft may have counter-rotating propellers, where one propeller rotates clockwise and the other counterclockwise. In such cases, it's crucial to identify the specific propeller and its rotation direction. #aerospace #propeller #engineer #drone #technology #Uav #Aerospaceengineer #aircraft

As I continue to optimize my Flying Wing UAV design, I leveraged ANSYS Discovery to generate velocity streamlines. These insightful visualizations reveal the airflow behavior around my design. Streamline Color Map: - Red: High-velocity regions - Yellow: Medium-velocity regions - Green: Low-velocity regions Key Observations: 1. Smooth airflow over the wing surface, with minimal turbulence. 2. High-velocity streamlines near wingtips, indicating potential drag reduction. 3. Flow separation at trailing edge, suggesting optimization opportunities. Streamline Patterns: - Converging streamlines: Indicate regions of acceleration, essential for enhancing lift. - Diverging Streamlines: Reflect areas of deceleration, providing insights into performance adjustments. - Circular Streamlines: Reveal recirculation zones that may indicate flow separation. This analytical approach not only deepens my understanding of UAV aerodynamics but also facilitates innovative design optimization strategies. I look forward to further refining this design and contributing to advancements in the aerospace field. #Aerodynamics #UAV #FlyingWing #ANSYS #VelocityStreamlines #AerospaceEngineering #Innovation #DesignOptimization

I am happy to share an interesting project about the design of a small drone (UAV) frame, according to "polymer perspective". Viscoelastic response, yielding and damage were assessed in different conditions, although the mechanical response in polymers is not a trivial problem. For sure this could be optimised by applying a damage tolerant design. 💪 #polymers #mechanics

Reticulum - big picture? There is now initial page up for upcoming notes on Reticulum network and Edgemap at my Wiki [1]. You may check introduction part and hopefully I am able to expand it to more technical details in near future. I suggest you copy picture to your teams for discussion and offer me some 'not possible' comments - because they are my main motivator!

Perfect Propellers for Peak Performance 🌬️✨ Welcome back! Today, we’re focusing on propellers – the unsung heroes of drone propulsion. Propellers create the thrust needed to lift and maneuver your drone, and choosing the right ones is crucial for optimal performance. Understanding Propeller Dynamics: Diameter and Pitch: The diameter is the total length from tip to tip, while the pitch is the distance a propeller would move in one revolution if it were moving through a soft solid. Larger diameters produce more thrust, and higher pitches increase speed. Blade Count: More blades can increase thrust but also add more drag, potentially decreasing efficiency. Common configurations include two-blade, three-blade, and four-blade propellers. Materials: Propellers are made from various materials like plastic, carbon fiber, and composite blends. Carbon fiber is lightweight and strong, reducing vibration and improving performance, but it can be more expensive. 🔍 Insight: Matching the propeller to the motor's KV rating and the drone's intended use is key. For racing drones, smaller, higher-pitch propellers work best. For aerial photography, larger, lower-pitch propellers provide stable, smooth flight. Next post, we’ll delve into the battery – the lifeline of your drone! ⚡️ #DronePropellers #FlightDynamics #UAVDesign #DroneInnovation #Aerospace #Engineering #TechTalk #PropulsionSystem
