“We decided that unified controls is a proven direction to go,” he says, referring to systems that allow vertical takeoffs and landings to be executed with one hand. The advanced systems relay commands every few milliseconds via pilot input to help automate flight, the endgame being a much safer, more intuitive generation of aircraft. MachUp is a free, online aerodynamic analysis tool used for aircraft design, analysis, and optimization. This tool was developed by graduate students under the leadership of Dr. Doug Hunsaker at Utah State University. I myself have been working on the development of MachUp for over a year now.
NASA-Led Study Provides New Global Accounting of Earth’s Rivers
When onboard pilots are not required, the diversity of practical vehicle configurations grows. Today, drones help in the study of coral reefs, high-altitude long-endurance observation and communications, and aerial photography. Future applications may include delivering packages in urban regions, medicines in remote areas, or even people, as driverless cars help pave the way for new forms of air transport.

Boeing similarly has decades of production and support contracts remaining for its CH-47 Chinook, AH-64 Apache and other military rotorcraft. Army Signal Corps bought a Wright Military Flyer from the Wright brothers for $30,000, and has kept apace for more than a century as dozens of aircraft types were converted for the armed forces. Military-technology transfer is now advancing even more rapidly into the civilian market, with the latest generation of electric aircraft currently undergoing flight testing in preparation for certification in the next few years. At first glance, private jets and military aircraft couldn’t seem further apart. But in the gray area between coddling luxury and mission-based efficiency, there’s a rich history of innovation exchange that has helped both categories stay on the bleeding edge of aviation.

Electrification in aviation is all about how you manage to propel your airplane forward so you can reduce the amount of fuel burned but still get the desired power during every phase of flight – from taxi, to takeoff, to cruise, to landing and taxi again. In China, the Airbus Beijing Engineering Centre’s core activities involve specific design packages for new aircraft programmes. Ltd. focuses on the development of advanced capabilities in the areas of modelling, digital simulation, and visualisation.

But many others will leave, with their unique engineering expertise lost to the military rotorcraft industrial base. Future aircraft design will rely heavily on these simulations, extending their use in large-scale optimization and uncertainty quantification. A variety of computational tools is needed for conceptual design to shape optimization. These tools range from reduced-order computational models for the development of design space exploration strategies and rapid design optimization to high-fidelity computational models for trouble-shooting and performance assessment. Although the efficiency of commercial jets has improved dramatically since their introduction, the effect of airplanes on the global and local environments is significant. The Department of Defense will design, develop and field a fleet of next generation air vehicles that will ensure the United States’ dominance in the vertical lift domain throughout the 21st century and beyond.
New technologies for autonomous flight vehicles
In order to succeed, it is important to properly frame your issue by identifying key design requirements. Creating a process map is the first step towards designing and building a new aircraft. Aviation’s decarbonisation relies on a mixture of incremental steps and outright technological breakthroughs. In this spirit Airbus, DLR and ONERA, two leading European research institutions, are exploring how high-performance computing can improve our understanding of the relationship between aerodynamics and aircraft efficiency.

The final product is a conceptual layout of the aircraft configuration on paper or computer screen, to be reviewed by engineers and other designers. The design configuration arrived at in the conceptual design phase is then tweaked and remodeled to fit into the design parameters. In this phase, wind tunnel testing and computational fluid dynamic calculations of the flow field around the aircraft are done. Aerodynamic flaws and structural instabilities if any are corrected and the final design is drawn and finalized. The white space tackled by eVTOLs has brought with it the opportunity to invent new flight-control systems for easier, safer operation. “We’d been researching the best way to control a vehicle of this class,” explains Joby Aviation’s Peter Wilson.
The jet engines also can power generators to directly supply electricity to the electric motors, or to charge batteries for the electric motors to use later. This can mean an all-electric airplane in which electric motors turn propellers or fan blades to generate thrust. Such a capability could enable all sorts of new ways airplanes could be designed, either by modifying current airplanes or coming up with new configurations. It must move through the air easier, possibly use electricity to augment or power the propulsion system, and it must be as lightweight as is safely practical.
A minimum clearance is required, and you can only make the landing gear so long before it weighs too much or takes up too much room when stowed. The design office at Airbus’ headquarters in Toulouse, France gathers top-level competencies such as architecture integration, general design, structural design and computation, integration tests and systems, as well as propulsion. In 2022, Delta and American Express launched the first iteration of the limited-edition Boeing Delta 747 Card design, one of the most iconic airplanes in aviation history. The new design is made with 33% metal from a retired Delta Boeing 747 plane and has a white glossy finish, which is inspired by clouds.
This is a safety feature to contain and minimize any danger that might arise should an engine catastrophically fail in flight. To reduce aviation’s impact on climate change you must reduce greenhouse emissions. Like a set of Russian matryoshka nesting dolls, they fit within each other to provide a whole idea, one that especially resonates with what Earth Day is all about – working toward a cleaner environment at a time of global concern over climate change. Operability engineers have the responsibility of ensuring the design is maintainable and parts are accessible. The task of industrial architects is to define the best industrial system and assembly flow, while costing experts predict components cost and assist with design-to-cost approaches that keep the costs down. The role of load engineers is to establish the sizing of loads for all components, taking into account all potential load cases the aircraft may encounter during its operation.
My work specifically has related to calculating the aerodynamics of the propellers and modeling how prop-wash can affect the aerodynamics of lifting surfaces, like wings. Using this tool, aspiring aircraft designers with little to no knowledge of aerodynamics or aeronautical engineering can design their own aircraft. From a simple flying wing to a canard with distributed electronic propulsion, MachUp allows users to design their own aircraft and easily analyze its aerodynamics. During the design phase, the definition and dimensioning of all elementary parts and their interfaces are performed, and the equipment, engines and landing gear are developed by the supply chain. In the integration and qualification phases, parts are produced and assembled – both for test specimens on test benches and for the first aircraft that will serve the flight test programme. The tests are organised as a pyramid, going from lab tests at a small scale (via integration tests for checking the behaviour of complete systems) to full-scale structural tests and flight tests.
The goal of all these tests is to verify predicted behaviour of the systems, structure and aircraft and to demonstrate their ability to sustain conditions well exceeding what is expected during the life of the aircraft – including also all conceivable failure cases. Years of subsequent joint studies envisioned an orchestrated approach to developing advanced military rotorcraft across all “capability sets,” from light scouts to heavy lift platforms. This structured plan telegraphed to industry what the military services’ long-range plans were, so companies could keep their design, development and production teams focused on both near-term and far-term objectives. Many of those 400 engineers that have now been laid off were previously hired away from other aerospace and defense companies and may stay in the vertical flight industry.
Brana also cites an example of this same technology flow but in reverse, in which the head-up instrumentation that debuted on the Mercure airliner later trickled up to the Mirage F1 fighter. By combining a bunch of wings and propellers, you'll be able to design an entire aircraft! For example, here is a DEP (Distributed Electric Propulsion) Aircraft that I designed based on a VTOL aircraft created by NASA. Its important to note that although I created a fuselage and nacelles using a couple of the other objects available in the 'Add' menu, the only objects that are currently used in the aerodynamic analysis are the wings and propellers. So any other objects you add are purely for visual appeal and don't actually affect the aerodynamics.

So, if you can’t make the overall engine wider in diameter, yet you want to increase the bypass ratio so more air flows around the core, then the solution is to make the core smaller in diameter. That’s because the engine – core and fan blades – must be contained in a housing, or nacelle.
