The story of the Me 309 is one of planning, strategy, overplaying and gamesmanship between manufacturers and World War II’s Nazi German government. When I received it my first thought was to look at the end notes where I saw the authors’ extensive use of Germany’s war archives (Douglas is fluent in Deutsch). Germany’s Air Ministry was well aware of the revolutionary high altitude super-heavy bomber in Boeing’s B-29 Superfortress. Specifically the Air Ministry knew how B-29s would fly high above the Luftwaffe’s current interceptors to deliver enormous bomb loads for the times. So…the Air Ministry was inspired to issue directives for a high altitude, heavily armed interceptor to defend their homeland against present B-17 and B-24 heavy bombers as well as future B-29 super-heavy bombers. Messerschmitt Me 309 is that story as well as the story of Jumo and Daimler-Benz designing and producing a much higher powered engine this new interceptor design would surely require. Newer, more powerful, engines at the beginning of their development cycles were also required in parallel. Willy Messerschmitt came through with innovative work. At first upgrading Messerschmitt’s veteran Bf 109G but this was denied since the airframe could not accept the newer engines being developed. His innovation continued, though, and the Me 309 was the resultant. This design eliminated the tail wheel and narrow landing track of the Bf 109 which was intuitively expected to reduce landing accidents inherent to the Bf 109. More powerful engines would increase prop torque so a tricycle landing gear arrangement would also aid in reducing take off incidents. A pressurized cockpit would greatly increase the number of pilots who could fly high altitude intercept missions. A variety of machine gun and cannon combinations were profeered using 13mm machine guns and 20mm as well as 30mm autocannon weaponry. Added to this stew of frustration for Nazi Germany was Willy Messerschmitt’s desire to remain with the Bf 109 production line. The jigs were there. The manufacturing bugs has been all but eliminated. Messerschmitt’s strategy delayed Me 309 development by one or two years. There are many other insight these learned authors provide to their readers. The pros and cons of standard bearings versus roller bearing, especially when pushing oil through these bearing in an engine. The design challenges which were overcome by Jumo and Daimler, as well as why Daimler’s engine became a fighter engine standard and the Jumo a bomber engine standard. Messerschmitt Me 309: Development & Politics also delves a bit into a facet of a country at war which is usually left unaddressed which is the economic dimension.

After years of work and preparation, EaglePicher can now publicly announce that we were selected to develop and build Saab's Gripen E advanced Li-ion Battery based on technology developed by our expert engineering team that enables battery start of the engines in extreme cold/harsh environments. As effective as Li-ion Batteries are for everyday devices, aviation batteries require a much higher degree of safety, performance, and cycle life all of which we base our design and reputation on. https://lnkd.in/gdTUwBBK <iframe src="https://lnkd.in/guDUCiMi" height="573" width="504" frameborder="0" allowfullscreen="" title="Embedded post"></iframe>

Ensuring Durability and Safety: The Role of Potting Boots and Backshells in Aircraft Electrical Harnesses Posted by Terry Cedar on May 15, 2024 At Alpine Aviation, we understand that every component in aircraft manufacturing is crucial for ensuring flight safety and reliability. Among these, potting boots are essential yet often overlooked elements in electrical harnesses. Today, we explore how potting boots enhance durability and safety in aircraft electrical systems. What Are Potting Boots? Potting boots are protective enclosures that shield the termination points and splices in electrical harnesses. Typically made from materials like silicone or epoxy resins, these boots encapsulate electrical components to protect against moisture, dust, vibration, and extreme temperatures. The Importance of Potting Boots The primary function of potting boots is to safeguard sensitive connections within the harness from harsh aviation environments. This is vital for preventing failures due to corrosion, electrical shorts, and physical damage. Enhancing Reliability and Safety Potting boots are critical for maintaining the integrity of aircraft electrical systems during the severe stress and vibrations of flight, extending the lifespan of components and reducing maintenance needs. They also bolster safety by preventing moisture and contaminants from causing electrical failures, which is crucial for avoiding catastrophic outcomes. Compliance with Standards Adhering to stringent industry standards is a must, and potting boots play a significant role in meeting these requirements by adding an extra layer of protection needed in both military and commercial aircraft. Integration Process Choosing the right materials for potting boots involves evaluating thermal conductivity, electrical insulation, chemical resistance, and mechanical strength. The application process, requiring precise encapsulation of components, along with rigorous quality control checks for adhesion and coverage, ensures each harness meets aerospace standards. Conclusion Potting boots, while small, have a significant impact on the safety and efficiency of aircraft operations. At Alpine Aviation, we are committed to integrating these protective measures to ensure each flight is as safe and reliable as possible. #DefenseIndustry #Aerospace #Aviation #AvGeek #AerospaceIndustry #AviationIndustry #Blackhawk #UH60 A/L/M #WireManufacturing #UH60V #Aerospace #AerospaceIndustry #Aviation #Defense #SpaceIndustry #Innovation #Success #AvGeek #USMilitary

The technology company VINCORION has signed a contract with KNDS Germany (Krauss-Maffei Wegmann GmbH & Co. KG) for the delivery of more than 700 EPG huskyV W 600 onboard generators for the Boxer. Additional orders for future projects are expected, meaning orders for a total of more than 1,000 generators are anticipated. This demonstrates the performance of the company’s military energy systems in armoured vehicles, too. The new VINCORION generator, the EPG huskyV W 600, is a water-cooled onboard generator for use in all scenarios: in the Boxer, it can see to the vehicle’s power supply as well as supplying the various mission modules as it supplies power of up to 600 amperes, making it ready for future requirements, too. A new digital voltage regulator has been incorporated, enabling the generator to be adapted to different applications. “Delivery of the generator for the Boxer is a very important order for us,” says Dr. Stefan Stenzel, managing director of VINCORION. “This tells us demand for the Boxer remains high. It also shows that manufacturers of modern military technology are placing their trust in VINCORION components and are using these to equip their vehicles.” Find out more: https://lnkd.in/d9FBcZJM #Germany #defence #industry #technology #VINCORION #KNDS #KMW #Boxer #armoured #vehicle #military

New EDA project to advance work on hybrid drive trains for military vehicles To improve the sustainability of future defence mobility while retaining the highest performance demanded by military vehicles, the European Defence Agency has been working on the development of hybrid drive trains for military use. EDA has formally kicked-off the #HybriDT II (Hybrid Drive Train Demonstrator-phase 2) – project which involves the design of full-scale wheeled and tracked military purpose demonstrators with hybrid drive trains. The aim of HybriDT II is the design of demonstrators to verify simulation results and allow for tactical and logistic testing of new technologies. Wheeled vehicles will be the primary focus of the research, with 8×8 and 6×6 Infantry Fighting Vehicles (IFVs) will be considered. In addition, tracked vehicle applications will be investigated just within simulation.

The USS John F. Kennedy launching car like objects weighing up to 80,000 lbs. into the river to test their #aircraft electromagnetic #launch systems. In #manufacturing, the cost of fixing defect/error multiplies exponentially as the issue is realized later and later in process. Its most expensive to repair a defect if the defective part gets to the customer. While it’s less costly to detect an issue while producing the part than when it gets to the customer, it’s cheaper still to find the issue in the prototyping/design phase. The Navy and shipbuilder have obviously done plenty of testing in the prototyping phase to de-risk the potential of any faults. They’re smart to continue verification testing towards the end of the ship production stage. Catching a problem at the end of the production stage, while costly, will be far less expensive once the ship has been commissioned; especially when you consider that the aircraft and even Pilot’s life is the ultimate cost to a design or quality flaw not caught beforehand. This is why it’s critical to have thorough testing and quality built into the manufacturing process. As someone who works with sales and customers daily, I’m glad I work for a quality company that prioritizes customer satisfaction; through quality and testing, throughout all stages of the process. https://lnkd.in/eqx2nvBg
