Aircraft conceptual design involves sketching a variety of possible configurations that meet the required design specifications. Fundamental aspects such as fuselage shape, wing configuration and location, engine size and type are all determined at this stage. Constraints to design like those mentioned above are all taken into account at this stage as well.

Junior engineers were hired at inflated salaries and higher cost to the taxpayer, but a lack of domain expertise contributed to significant cost and schedule delays for the ill-fated Comanche program. It takes years to build up a talented aircraft design team, but only a moment to lay them off. In the case of national defense, citizenship and security clearance requirements make hiring and training specialized rotorcraft engineers all the more difficult, expensive and time consuming. Start developing a network of industry contracts “early in your engineering education,” advises Wolz. “Look for opportunities to network, and for practical work experience through internships and co-ops (cooperative education programs).” Sturdza notes he began working with Aerion when writing his Ph.D. thesis on laminar flow technology, inspired by Aerion’s founder. “Sending out your resume is not nearly as effective as having some sort of relationship” with a potential employer, Sturdza says.

You'll also be able to set the rpm's or throttle setting (if you specified a motor for all your propellers) of the propellers. Now, with the propeller selected, you can modify elements of it's geometry, including the number of blades, the pitch , diameter, and airfoil characteristics. You can even specify the characteristics of your power system including the motor, esc, and battery. MachUp will then use this information to give you an estimate of how the propeller will operate at a given flight condition and throttle setting. “A difference in generations” is appearing in the aeronautical workforce, Wolz says, with today’s hires eager “to get on the fast track.” But careers typically progress less rapidly than the aircraft the field creates.

The multidisciplinary aspect is key to the concept of concurrent engineering at Airbus, where all relevant skills are brought together with the goal of reducing the time and effort required during an aircraft’s development. Concurrent engineering at the company is characterised by a strong sponsorship at the top engineering levels, and discipline throughout the organizations to define and fully apply common processes and common methods – all of which are supported by common tools. Sikorsky has plenty of valuable production work for decades to come, including the Black Hawk, Seahawk and the Marine Corps’ heavy-lift CH-53K King Stallion, arguably the world’s most advanced helicopter in operation today.

An aircraft’s development brings together multidisciplinary teams that work in a highly collaborative environment, uniting teams of different skills including various engineering disciplines, along with manufacturing, customer services and procurement. Bell and Sikorsky were downselected in March 2020 and each hired hundreds of engineers to support the development of these next-generation rotorcraft, meeting the Army’s challenging timeline. A major change for CCA, compared to past GA-ASI programs like MQ-1s and MQ-9s, was the expectation from the beginning that many will be built.

Brian Everstine is the Pentagon Editor for Aviation Week, based in Washington, D.C. Before joining Aviation Week in August 2021, he covered the Pentagon for Air Force Magazine. Brian began covering defense aviation in 2011 as a reporter for Military Times. As GA-ASI progresses through the maturity of its CCA design, it will continue flying the XQ-67A largely to mature the sensor packages that a collaborative aircraft will need. After the announcement, the company will “put our heads down and go to work,” Alexander says.

With that said, if you design an aircraft and set the flight conditions within reasonable operating limits, MachUp will give very accurate results. We've compared the results produced by MachUp to both CFD and wind-tunnel tests and MachUp provides very accurate results in a fraction of the time that either CFD or wind tunnel testing would require. It has been used in a multitude of projects, including designing several advanced UAS systems employed by AggieAir for long-range, remote sensing missions. Most positions require a bachelor’s degree within a broad range of engineering or science fields in addition to aeronautics or astronautics, such as mechanical, electrical, structural, materials and even civil engineering. Other jobs might require training in systems safety, human factors, air-vehicle integration or aesthetic design.

The company’s S-92 is being delivered to the Marine One Presidential Helicopter Squadron and to civil and military customers around the world, albeit in small numbers. The transfer of aeronautical tech also continues to advance the business-jet world. Take the fly-by-wire hardware that first appeared on General Dynamics’ F-16 fighter. These digital flight control systems (DFCS) allowed for faster and more agile fighter jets and provided more flight consistency than conventional controls. The technology later appeared on the Dassault Mirage 2000, became a primary feature on the Falcon 7X, and is now standard across the Falcon line.

Blyth also recommends considering the type of company you want to work for — “a small company where you’re involved in every aspect of design and development, or a larger company where somebody might specialize in brakes” — before plunging ahead. One of the designs that came out of earlier research projects into future aircraft designs, the TTBW is essentially a classic tube and wing airplane but with a wing that is extremely long and thin. So long and thin, in fact, that it needs a little help on both sides of the fuselage to hold it up. In the feasibility and concept phases, market expectations and requirements are explored. Different options are combined to come up with an overall aircraft concept with the latest technologies, structural concepts and systems architectures. The result is a product specification to start detailed design of parts and the specification of system elements from equipment suppliers.

In the development of an aircraft, many disciplines work together to optimise the design. 1 The new limited-edition Boeing 747 Card design is made with 33% metal from retired Delta Boeing 747 aircraft. Sikorsky is the world's largest manufacturer of helicopters by value, with decades of production ...

Air Force Secretary Frank Kendall has given industry a planning figure of about 1,000 for the aircraft. Computational fluid dynamics (CFD) combines applied mathematics, physics and high-performance computing. It’s used to understand how air moves over complex shapes, helping designers maximise lift and minimise drag to make an aircraft as efficient as possible at both low and high speeds. Another way to get more fuel efficiency out of an engine is to change its configuration in terms of how air flows through it and at what pressures and temperatures.

For example, a company might have identified that there is a growing demand for small private jets. In the inital problem definition stages it is crutial to first identify the key requirements of the new product then to determine how realistic it is to create this product through a feasibility analysis. Although other revolutionary aircraft designs have been studied – such as the Double Bubble and Blended Wing Body – the TTBW technology shows the most promise for being ready the soonest. But if I can use electricity to help me out with certain parts of the flight envelope, I can design my engine differently and make it more efficient overall,” Kenyon said.

We'd like to add the functionality in the future to analyze other objects, like fuselages, we just haven't gotten around to it yet. From silent, efficient global transportation to personal or on-demand flight that frees us from roads, to autonomous air vehicles for delivery of information and goods, the future of flight will look considerably different than it does today. Our aircraft design research focuses on these enabling technologies and their application to future flight concepts. In the late 1990s, funding cuts to the Boeing Sikorsky RAH-66 Comanche stealth helicopter forced layoffs at both companies, and experienced software engineers were let go. When funding later increased and software engineers were again needed, the competition with commercial companies during the dot-com boom was unwinnable. Many experienced engineers had left the aerospace and defense sector, never to return, and the need for software engineers couldn’t be met.

These three companies, Bell, Boeing and Sikorsky, have been competing for military helicopter and advanced rotorcraft development programs for decades. For perhaps the first time since World War II, only one US manufacturer — Bell with its V-280 — has a significant military rotorcraft development program underway. Aircraft are complex systems that require subtle interactions between many components. Analysis of flight vehicles requires a multidisciplinary approach to modeling their aerodynamics, structures, dynamics, sensing and control systems, and propulsion systems. Methodologies to simulate these aspects of aircraft have increased in fidelity and complexity, enabled by dramatic improvements in computational capabilities.
