Software's role continues to expand Design teams use different technologies to create new software and link systems together. Emissions regulations and engine complexity With the European Commission announcing a Stage V criteria emissions regulation for off-highway, scheduled to phase-in as earlly as 2019, there will be an end to a brief era of harmonized new-vehicle regulations. Will this affect an already complex engine development process? Evaluating thermal design of construction vehicles CFD simulation is used to evaluate two critical areas that address challenging thermal issues: electronic control units and hot air recirculation.
Avionics go to war Advanced helmet sight systems are being designed to help the situational awareness of those pilots who actually still fly aircraft, while also being seamlessly integrated with the aircraft itself. Model military engine behavior While the concept of a variable cycle engine is not new, recent advances in engine architecture technology suggest that adding a second bypass stream to a traditional turbofan can provide significant benefits. Alternative seals for alternative fuels When considering seal compatibility an aircraft from traditional jet fuel to a synthetic fuel presents an interesting technical challenge that has both financial and practical considerations, especially for aircraft that are already in service.
Europe's aerospace industry looking confident Apart from Airbus's highly visible presence in defense and commercial aircraft, Europe also has successful capabilities in helicopters, business jets, and aero engines, and in all these areas their global market share is growing. Comparing blade-element momentum modeling to 3-D CFD Many small unmanned aerial vehicles (SUAVs) are driven by small scale, fixed blade propellers, and the flow produced by the propeller can have a significant impact on the aerodynamics of the SUAV itself.
Touch and go Avionics developments are changing life in the cockpit and at airborne work stations Sandwich cores for the future Decreasing weight while increasing strength is always critical, from airliners to future space missions to Mars. Research in sandwich cores today may lead to radical improvements in the future.
Powering on Rolls-Royce's Chief Engineer discusses how new technologies in the Trent XWB family of engines are inspiring current R&D design and evaluation work as part of its strategic roadmap for future big fanjets. Ongoing development work and associated test programs extend across a broad range of activities and involve many partners. Countering cybersecurity threats against unmanned vehicle systems Cranfield University researchers have developed a monitoring system whose purpose is to monitor mission profile implementation at both high level mission execution and at lower level software code operation to tackle specific threats of malicious code and possible spurious commands received over a vehicle's data links.
Booking flights on biofuel The aviation industry is now deploying biofuels on commercial flights after years of demonstration test flights, but high costs will keep bookings few and far between for a few more years. Beating brownout A look at a new airborne landing aid that provides safe-flight capabilities for front-line helicopter crews in degraded visual environments. Making battlefield targets disappear The use of 'smart' special materials has the potential to radically alter the way military platforms are defended, and used.
Next-generation military propulsion Design concepts for future strike aircraft, transport, and UAVs.
STOVL propulsion-onward and upward Rolls-Royce's unique Pegasus engine has made possible a generation of vertical-landing military aircraft. Testing solutions This special section highlights some of the latest equipment used by engineers to validate new technologies.
Full throttle for engine solutions Powering aircraft from Mach 2 fighters to tiny hovering UAVs, military engine technology is now operating on a very broad front. Design and production flexibility together with reduced in-service costs are priorities. To the breaking point Test engineers use new rigs and data-acquisition equipment on the latest generation of pneumatics, engines, and airframes. PCs move into the cockpit Pilot training is getting a bit less expensive with the introduction of more portable flight simulations.
Controlling UAVs BAE Systems and The Math Works work together on UAV flight software using embedded code generation and a high-integrity RTOS. Supporting aircraft evolutions Testing validates the technology, then the technology changes again. Time equals money A standard process for software cost estimation developed at Lockheed Martin streamlined the company's proposals for military projects.
Supporting nest-gen propulsion The need for advanced computational and communication systems on board military aircraft make fuel cells an attractive propulsion alternative, and ample access to hydrogen a necessity. Aerospace industry seeks material returns Better use of materials data can pay off for aerospace designers. Transatlantic testing program for the F-35 Europe gets its most comprehensive-ever military airframe test facility.
F-35 manufacturing ergonomics addressed Human-factors simulation from Delmia is playing a key role as Northrop Grumman tools up for work on the Joint Strike Fighter. Keeping it together: design, development, and maintenance It is only in relatively recent years that the full meaning of integrating manufacturing and maintenance as part of the design and development processes has been grasped by the aerospace industry. Exploring the boundaries of our solar system SAE 100 Future look: In addition to helping enable NASA's new vision of taking humans back to the moon and paving the way to Mars and beyond, two robotics space science missions are preparing to explore the outermost and innermost edges of our solar system. What's on the horizon for space SAE 100 Future look: Dramatic changes in the Earth's climate are certain to drive humanity's search for alternative fuel sources.
