Detail Design Having worked out a promising-looking layout, initial three-view and performance and weight specifications, now is the stage where the hard work begins of transforming concepts to working drawings. Essential decisions have to be made about types of material to be used, the structural arrangement, exact choice of powerplant and so on. You’ll probably need to make a cockpit mock-up to check the ergonomics and control system arrangements, and maybe build a flying radio controlled model of the design to give faith in the handling characteristics. With the basic geometry laid out, stress calculations and assembly drawings come next, then drawings of individual piece parts. Keep an up-to-date tally on weights. As the drawings get more detailed you must re-evaluate whether you are going to meet your original targets in terms of weight, strength and aerodynamic cleanliness, whether you need to re-visit your original assumptions or re-design from scratch. Is there a way that the part or assembly can be made more easily, more cheaply, lighter, stronger, more fatigue or corrosion resistant? Fewer parts and fewer joints generally means fewer problems and less weight. Can you use off the shelf parts rather than having to make them specially? Are there other aeroplanes around that have already solved a particular problem in a clever way? Will the aircraft be easy to inspect in service, easy to repair if it gets damaged? Can it be broken down for transportation? If the handling isn’t quite right when the prototype is test flown, does the design make provision for ‘tweaks’ to put it right? Does the design include reserves of strength to cope with weight growth in service and more powerful engines, or is everything pared down to the minimum? Design Tutorials

Permit Aircraft Electrics - Advanced Course Price Member - £224, Non-Member - £244 (includes printed course material) Duration Arrival 09:00. Finish 17:00. < Back About the Course The Basics course covers simple DC theory and concentrates on the practical aspects of installing a basic permit aircraft electrical system. The course explains how to interpret a ‘typical’ permit aircraft electrical systems diagram and for every element, explains how to size, select and source components and then how to practically install them. This Advanced course builds on the Basics course by providing more detail about component selection and options and the use of integrated power management systems within permit aircraft. The course takes the simple systems design introduced in the Basics course and explores options for creating more complex electrical systems including the use of dual and essential system bus bars. The course introduces fault tolerant design considerations, thus allowing attendees to consider safety and fault analysis in their own designs. As a tool for understanding this aspect of the course, it will take an introductory look into the requirements of electrical systems for those wishing to fly their aircraft under IFR. What this course will try to do is: Explain power generation and distribution options in a light aircraft More advanced consisderations into component selection Discuss circuit protection devices and systems Explain failure modes and reliability issues Introduce interference and EMC issues Show correct grounding and screening techniques Provide you with the knowledge to plan an installation and create the necessary documentation Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you overnight into an expert Enable you to fault find on an undocumented aircraft installation Delve inside avionics boxes It will be useful, but not essential, for people to have previously attended the Basic course. In order to make the best of this course, if you have not attended the basics course, you will need to understand basic DC theory; Ohms Law and the Power Law. Please note that this course is primarily a classroom based course, as you will already have the practical skills you need, which are covered in the basics course.

< Back LAA 'Grass Roots Fly-In' returns 23 Apr 2023 The LAA is returning to the green grass of Popham Aerodrome in Hampshire for a repeat of its “Grass Roots Fly In” from 18th to 20th August 2023. The Fly-In will again on one hand take the Associate back to its traditional roots, while continuing to offer the first chance to see some of the latest aircraft and products in the recreational aviation market. What was particularly notable about the 2022 Popham event was its sociality. LAA members and exhibitors alike commented on its relaxed and friendly atmosphere, with post-event comments such as “It’s a great reunion as well as a fly-in–cum trade show” and “super friendly, the event always had a good vibe”. A joint venture with Popham Aerodrome, the LAA Grass Roots Fly In will develop its strengths as a social event bringing flyers from around the UK and Europe to meet fellow enthusiasts. The grass runways at Popham and the airfield’s famed rural ambience will mean that the event will focus on the fly-in and social element as much as on a large exhibition campus. The earlier mid-August date will also mean longer evenings, allowing more scope for flyers from further afield and hopefully, milder conditions for those who choose to ‘camp under the wing’. Said LAA CEO designate Simon Tilling: “The LAA Grass Roots Fly In was a great success last year, with over 3,000 visitors, more than 30 exhibitors and a total of 350 visiting aircraft through the weekend. It is a different event to the past, larger scale LAA Rallies and we’re working on plans for the continuation of a larger scale LAA event in the future. For this year, we’re looking forward to another great, social and fun, LAA fly in”. Next Previous

< Back LAA Alert for Rotax 900 series engines regarding the oil spray nozzle 18 Dec 2024 Inspection and/or Replacement of Oil Spray Nozzle On 16.12.24, Rotax issued a new MANDATORY Service Bulletin SB 912 i-016/SB 915 i-016 / SB 916 i-006 which calls for urgent action for engines of specified models within certain serial number ranges, if the engine has run for less than 200 hours from new, or engines which have been fitted with specific overhaul kits supplied between 01.01.22 and 31.10.24 inclusive. The bulletin concerns problems with a possible full or partial blockage of the oil spray nozzle due to an excessive application of Loctite at the manufacturing stage, when assembling the sprag clutch housing. This can lead to inadequate cooling of the stator assembly, potentially causing loss of electrical power to the engine’s ECU.

< Back Mandatory Technical Directive issued for Jabiru 2200 engines 10 Jul 2024 Mandatory Technical Directive, MTD-05-2024 has been issued today to introduce mandatory checks on the clearance between the distributor cap and rotor arm in Jabiru 2200 engines where the cap or rotor have recently been changed (or following subsequent changes). This follows an in-service finding where differences in distributor cap design were found which lead to extreme wear in the components causing the engine to stop. The MTD must be carried out before further running of the engine on or after 10th July 2024 on Jabiru 2200 engines where the distributor cap and/or rotor arm has been changed in the last 20 engine hours, or are subsequently changed. The checks are also recommended on all other Jabiru 2200 engines. Next Previous
