Data obtained from digital flight data recorders are used to assess the actual operational environment of propellers on a fleet of Beech 1900D aircraft in commuter role.

Back in the sleeping compartment, completely unattended, automatic flight recorders and an automatic temperature recorder system continuously gather all possible information on the operation of the engines, controls, and performance of the airplane.

For example, it requires very specific knowledge to boot a hybrid system, manage its configuration process, and start and stop the execution of applications, such as simulations, panels or recorders. Likewise, when testers use a heterogeneous test environment, they cannot commit themselves too much to every single test means and its special characteristics.

SAE EDGE Research Reports provide examinations significant topics facing mobility industry today including Connected Automated Vehicle Technologies Electrification Advanced Manufacturing

The Convair/Navy XFY-1 VTOL fighter was ahead of its time. In the early 1950s it became the first airplane to take off vertically, hover, transition to high speed level flight, transition back to hover, and land vertically. Pilot “Skeets” Coleman made a number of successful flights at Moffett Field South of San Francisco, at Brown Field near the California/Mexican border, and at San Diego's Lindbergh Field. This “first of a kind” aircraft soon adopted the name “POGO”. The POGO with its stall proof delta wing had near perfect aerodynamic characteristics in hover, transition and level flight. There were no “black boxes” needed for stability augmentation. The POGO was one of the very first aircraft to use hydraulic power flight controls - a system used today on all modern fighter and transport aircraft.

Uncertainty quantification The technique is a must for next-generation simulation tools. Oil-pump sizing Researchers from Hinduja Tech investigate options for low friction and power consumption. The future of Indian commercial aviation The growth in traffic that airport modernization has supported has also made a significant contribution to the local and national economies, while the improved infrastructure has been positive for the perception of India in the global market. Driving EVs toward lower cost The race ison to reduce battery and electric-drive systems cost while improving efficiency. Powering on Rolls-Royce's Chief Engineer discusses new technologies that inspire current R&D design and evaluation work as part of its strategic roadmap for future big commercial programs. HMIs extend beyond the cab Telematic functions are being integrated into multi-function user interfaces.

This SAE Aerospace Information Report (AIR) summarizes prior empirical findings (AIAA 2018-3991; Chati, 2018) to recommend a modified baseline fuel flow rate model for jet-powered commercial aircraft during taxi operations on the airport surface that better reflects operational values. Existing standard modeling approaches are found to significantly overestimate the taxi fuel flow rate; therefore, a modified multiplicative factor is recommended to be applied to these existing approaches to make them more accurate. Results from the analysis of operational flight data are reported, which form the basis for the modeling enhancements being recommended.

The TIMED spacecraft is implementing an Integrated Electronics Module (IEM) that contains several different spacecraft subsystems, like C&DH, S-band receiver and transmitter, solid-state recorder and more. The combination of all these subsystems into one box, normally packaged in separate card cages, has resulted in some challenging thermal design problems.

Military maneuvers Electronics and avionics designers put control in the pilot's hand. Propelling commercial aircraft GE Aircraft Engines calls upon its engineers, and those of its "competitors," to develop a series of next-generation engines. Bonded repairs Aircraft structure repair is process-sensitive, requiring attention to detail, particularly in terms of both composite and metal surface preparation.

This document provides industry guidance to supplement ATA standards and airframe requirements, addressing gaps and vague areas to move suppliers/vendors and airframers toward a common standard for format and wording in Vendor Service Bulletins (VSB) for Air Transport components. This document supplements the VSB guidance of iSpec 2200, providing clarity of requirements and resulting in a common standard wording and format of VSBs from all suppliers on all aircraft types. The guidance in this document is intended to be applied to VSBs created and released subsequent to the release of the guidance document and will not require the retroactive update of VSBs released prior to the creation and release of the guidance.

Military engines: cost and capability Industry experts provide a glimpse out at the 2020 vision of military propulsion. Manufacturing propellers Dowty Propellers uses a secure data-logging system for its fabrication process.

Noise and vibrations control A variety of active and passive methods can be used to reduce cabin noise and fuselage vibration. Bringing efficiency to flight testing To meet itsgoal of one new aircraft activity each year, Bombardier's Flight Test Center has sought to reduce aircraft development cycle time by focusing on test planning, safety, and configuration control. Propulsion flight testing Originally conceived for just the GE90 aircraft engine program, GE Aircraft Engines' Boeing 747 flying test bed has evolved into the company's primary commercial engine test aircraft. Top technologies for 2000 Each month, "Aerospace Engineering" publishes the latest technologies. The "Aerospace Engineering" editors have reviewed thousands of reader responses during the past year and have chosen the "best of the best" along with runners-up.

The Nano in retrospect A senior graduate student in the Department of Mechanical Engineering at the Indian Institute of Technology looks at the development of the world's cheapest car and its effect on Indian car users. A different riff on your basic two-seat electric car Markus Lienkamp, Chair of Automotive Engineering at the Technical University of Munich, is leading the Visio.M project, a German government-supported R&D effort to produce a low-cost, high-utility electric car that might attract the interest of the middle European mass market. Materials lead the way to vehicle mass reduction Reducing a vehicle's mass opens the door for a downsized engine and transmission, a lighter cradle and body structure, smaller wheels and brakes, as well as a weight-slimmed suspension. The start point for this ripple effect is materials.

This document defines general system architectural philosophy and specific design guidance for the design and interface of various cabin related equipment. System performance parameters are described for connectors, electrical interfaces, operational mode control/protocols, BITE reporting, reliability, environmental conditions, and software data loading. Supplement 7 defines an IEEE 802.11n compliant Cabin Wireless Access Point (CWAP) suitable for installation a wide variety of cabins. It also provides an update to the digital overhead monitor mounting provisions and connectors for compatibility with the CWAP definition.
