Selection of materials, manufacturing methods and lubricants Methods for designing parallel axis straight spur and helical gears Method for calculating contact and root bending stress limitations, compatible with BS There are some exceptions, but this is happening quite often lately. If you get the reputaion of a FAA time waster, your projects will rarely see the light of day. Recent News As detailed at the link in my post above, the current FAA plan is to begin charging for the handbook to help defray the costs of maintaining the docuement. The answers that we obtain using the ESDU methods also tend to be more accurate because they are based on a combination of theory and experimental data, rather than theory alone.

Taular The Eng-Tips staff will check this out and take appropriate action. The End of Mil-Hdbk-5 forget that! Try turning them off temporarily if you can or are allowed to. I pasted the wrong link in my post above. Flight-test handling measurements Analysis using equations of motion Reduction to standard conditions by incremental adjustment Non-dimensional group presentations Correction of air-data measurements and methods of in-flight thrust measurement for turbo-jet and turbo-fan engines Related Tools International Standard Atmosphere ISA app Wing lift-curve slope app Physical Data The most reliable correlated data available equations and in tabular form for the physical properties of a wide range of pure compounds and some mixtures used in the chemical industry, including: Engineering and academic professionals use ESDU to: The End of Mil-Hdbk-5 Several military standard documents are being taken by non-military groups.
Nigel Waterhouse Can-Am Aerospace www. A Legacy of Leadership. As a side note, the government is exdu debating who should be overseeing public aircraft includes VIP, firefighters, etc. Recent News Learn how the company used IHS Markit proprietary data and market forecasts, and worked with IHS Markit analysts, to secure a sale in a region where it had never before conducted business. Established in to further the art, science and engineering of aeronautics, the Society has been at the forefront of developments in aerospace ever since.
Anyways, I think the addition of data and revisions will be far fewer in the future. I have Mil-Hdbk 5 you can download it for free.
Not sure if you guys are aware but the government including the military is moving closer and closer to using the FAA to cover more of the certification burden. The End of Mil-Hdbk-5 Guys. Towards the end of the s, grant aid was withdrawn and ESDU became a commercial entity selling subscriptions to its services. ESDU provides validated engineering analysis tools to engineers and teachers in the aerospace engineeringprocess engineering and structural engineering fields.
This means I am able to get alot more stuff through at the same same time. Make it easy and reap the rewards. Check foir yourself at http: The MIDO just breezed through everything as they have a budget per company to stick too.
True, the FAA are responsible for safety and , but so are we professionals. I believe these too will come under the FAA umbrella soon enought. Methods and data for the design, analysis and selection processes associated with lubricants, lubrication, friction, edsu and bearings, including:. Process Engineering Methods and data to evaluate or predict the performance of process plant equipment and process systems.
A Fortune aerospace company that is addressing industry-wide engineering and knowledge essu challenges — by using a new system to harness internal and external technical information and derive new ideas across numerous projects — reports a fold return on investment within the first year. Knowing what to give the FAA and in what format it is to be presented is sometimes half the battle. I also have to compute B-basis allowables.
Perish the thought that they might spend all their time doing that, instead of, say, pushing through the Sport Pilot licencing like they were supposed to last year. MMPDS is available in digital format at www.
Another possible cause is that if you pull from multiplie servers sometimes one will become bogged down and time you out. By joining you are opting in to receive e-mail. H, everyday and have two copies one at work and home. Much faster than normal — got lucky with traffic I think. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

ESDU: Validated engineering design methods
Summary Abstract: The design engineer faces an ever-increasing demand for products with a performance that must be substantiated under stringent conditions of cost and environment. Assuming the basic skill of the designer, no other single factor can contribute more to the economic preparation of a satisfactory, competitive engineering design than ready access to good reliable design data. Data concerning aerospace structural materials are widely scattered and, when located, are of variable quality and relevance to industrial applications. The task of collecting and evaluating all the relevant data available on a particular material property is time consuming and therefore expensive. Even if such a task is performed it is often found that the customer will wish to view the design, not against some locally derived data, but against what can be demonstrated to be the best data that can be ascertained and which are vouched for by a significant cross-section of the engineering and scientific community concerned with both derivation and application of materials data. Accordingly, this Handbook has been prepared to meet design requirements with regard to aerospace structural metallic materials properties for both the designer and his customer and, by serving the needs of many, accomplishes the task at much lower cost and with a higher reliability than could the individual.
