The inclusion of an aircraft type in the licence does not indicate that the aircraft type has been granted a type certificate under the Regulation (EC) No 216/2008 and its Implementing Rules; this list is only intended for maintenance purposes. In order to keep this list current and the type ratings consistent, such information should be first passed on to the Agency using the Rulemaking Enquiry form (http://easa.europa.eu/webgate/rulemaking-enquiry/) in case a Member State needs to issue a type rating that is not included in this list. Notes on when the licences should be modified: When a modification is introduced by this Decision to an aircraft type rating or to an engine designation in the rating which affect licences already issued, the ratings on the Aircraft Maintenance Licences (AMLs) may be modified at the next renewal or when the licence is reissued, unless there is an urgent reason to modify the licence. Notes on aircraft modified by Supplemental Type Certificate (STC): — This Appendix I intends to include the type ratings of aircraft resulting from STCs for installation of another engine. These STCs are those approved by the Agency and those approved by the Member States before 2003 and grandfathered by the Agency.

    ICAS 2000 CONGRESS COMPUTATIONAL AEROELASTICITY IN HIGH PERFORMANCE AIRCRAFT FLIGHT LOADS* Mike Love, Tony De La Garza, Eric Charlton, Dan Egle Lockheed Martin Aeronautics Company Keywords: computational aeorelasticity, CFD, flight loads Abstract A computational aeroelasticity method has been developed that combines a compu- tational fluid dynamics (CFD) code based on a finite volume, Cartesian / prismatic grid scheme with automated unstructured grid creation and adaption with established structural finite element methods.

    Diesel, Spark-Ignition, and Turboprop Engines for Long-Duration Unmanned Air Flights

    JOURNAL OF PROPULSION AND POWER Diesel, Spark-Ignition, and Turboprop Engines for Long-Duration Unmanned Air Flights Daniele Cirigliano,∗ Aaron M. Frisch,† Feng Liu,‡ and William A. Sirignano‡ University of California, Irvine, California 92697 DOI: 10.2514/1.B36547 Comparisons are made for propulsion systems for unmanned flights with several hundred kilowatts of propulsive power at moderate subsonic speeds up to 50 h in duration. Gas-turbine engines (turbofans and turboprops), two- and four-stroke reciprocating (diesel and spark-ignition) engines, and electric motors (with electric generation by a combustion engine) are analyzed. Thermal analyses of these engines are performed in the power range of interest. Consideration is given to two types of generic missions: 1) a mission dominated by a constant-power requirement, and 2) a mission with intermittent demand for high thrust and/or substantial auxiliary power. The weights of the propulsion system, required fuel, and total aircraft are considered. Nowadays, diesel engines for airplane applications are rarely a choice. However, this technology is shown to bea very serious competitor for long-durationunmanned air vehicle flights. The two strongest competitors are gas-turbine engines and turbocharged four-stroke diesel engines, each type driving propellers. It is shown that hybrid-electric schemes and configurations with several propellers driven by one power source are less efficient. At the 500 KW level, one gas-turbine engine driving a larger propeller is more efficient for durations up to 25 h, whereas several diesel engines driving several propellers become more efficient at longer durations. The decreasing efficiency of the gas-turbine engine with decreasing size and increasing compression ratio is a key factor.

Sure, if you’re a math robot, an equation is enough. The rest of us, with organic brains half- dedicated to vision processing, seem to enjoy imagery. And “TOA” evokes the stunning beauty of an abstract ratio. I think you deserve better, and here’s what made trig click for me.

Without new words, humans are hard to describe: “There’s a sphere at the top, which gets scratched occasionally” or “Two elongated cylinders appear to provide locomotion”. After creating specific terms for anatomy, Bob might jot down typical body proportions (http://en.wikipedia.org/wiki/Body_proportions): The armspan (fingertip to fingertip) is approximately the height A head is 5 eye-widths wide Adults are 8 head-heights tall http://betterexplained.com/articles/intuitive-trigonometry/ Page 2 of 48 How To Learn Trigonometry Intuitively | BetterExplained 9/26/15, 12:19 AM (http://en.wikipedia.org/wiki/Vitruvian_Man) How is this helpful?

    Structural Certification of the F-16 Block 52+ Aircraft 29 November 2005 2005 USAF Aircraft Structural Integrity Program Conference Robert J. Burt Director and Deputy F-35 Structural Development and Integrity Lockheed Martin Aeronautics Company Fort Worth © 2005 LOCKHEED MARTIN CORPORATION Lockheed Martin Aeronautics Company Structural Certification of the F-16 Block 52+ Aircraft Abstract This presentation will describe in some detail the process followed by Lockheed Martin Aeronautics – Fort Worth for the structural certification of the new production F-16 Block 52+ aircraft for foreign military sales (FMS). The F-16 Block 52+ aircraft are structurally upgraded from the USAF Block 50/52 aircraft due to carriage of the fuselage shoulder mounted conformal fuel tanks and due to the addition of numerous advanced systems. The structural requirements and their methods of verification are set forth in the program contract and subsequent program documents such as the weapon system specification and air vehicle specification. Every USAF and FMS F-16 has an Aircraft Structural Integrity Program (ASIP) based upon program contractual requirement and tailored to MIL-STD-1530B Aircraft Structural Integrity Program. An ASIP Master Plan has been written for the Block 52+ aircraft which has been coordinated with and approved by the USAF F-16 System Group. This ASIP Master Plan states in specific terms how all the tasking outlined in the “five pillars” is accomplished. An overall design process will be discussed in depth pointing out how all historical structural analysis, structural test and field information has been used in the structural design of the Block 52+ aircraft.
