Magnus is a two seat, side-by-side advanced light-weight airplane family. The Magnus, with its custom designed wing profile is a unique multi functional and multi purpose single engine aircraft for primary and advanced flying. The Magnus combines the unequalled advantages of a high performance motor-glider with unparalleled efficiency during powered long-range cruise flight. Because it is equipped with high-tech features such as flaperons, wing upper side effective airbrakes and a ground adjustable or variable-pitch propeller the Magnus can excel at every task pilots put it to. Magnus exploitation and handling costs are low due to the simple design solutions and high aerodynamic performances. Advanced design engineering concepts, gliders designs advantages, excellent aerodynamics and unique safety features make it the performance future orientated choice of Ultra Light- and Advanced Light Aircraft categories. Magnus and Mingus load measurements, structural dimensions, calculations and proofs of compliance are being completed by the Magnus family experienced design team. This will result in certification in category UL LTF in Germany (MTOM 472.5 kg) and in ULA categories of many European countries (MTOM 450 kg) and with no technical changes in category LSA for US of America and in coming ELSA for Europe as well (MTOM 590 kg). Magnus (13,35 m / 43,8 ft span, 80 hp engine) deliveries will start first, Mingus (10,6 m / 34.8 ft span, 100 hp engine) deliveries will continue and Maxus with its 17 m + / 55,8 ft + wing span (wing candidates: custom design, LS6-18w modified, LS4-b modified) will make first flights in the second half of the year 2011. Factory accepts final orders and purchase option pre-orders for all three models. Magnus New airplane series design definition No. 1 is the complete new modern airplane multi model, stemming from Magnus basic design, as: - a basic moderate and high aerodynamic characteristics 13,35 m span, low wing motorglider with winglets, - easier to hangar than comparative 15 m span touring motorgliders, - having about the similar soaring performances as comparative fixed faired 15 m span taildraggers, - but faster speed capability with same 80 hp maximum power installed in the nose, - low empty weight construction of simple and reliable engineering details using materials as carbon fabric, Aramid honeycomb and Titan as well. The Magnus 13,35 m wing section is the latest state of the art. The wing-fuselage intersection was optimized with special aerofoil’s in this area, wing plan-form and dihedral make Magnus aesthetics and add the advantage at low speeds, than effective and Magnus unique designed winglets will result in a “larger” comparative wing span of approx 14,4 m. Another additional lift producer to the taller winglets is the lifting body shaped fuselage, which is also influenced by wing circularly lifting vortex, enhancing the lifting ability of the isolated body. Exact performance figures will be available once flight tests have been done. The best glide ratio of Magnus with 13,35 m span in retractable gear version was calculated with 32 : 1 and in fixed tricycle gear version with best L/D 28 : 1. Magnus aerodynamic design was done from Italian designer and aerodynamicist Mr. Franco Orlando who designed successfully already more known Italian and Slovenian airplanes and many of the very good new wing aero-foils. For easier transport by trailer or hangar storage the wings of the Magnus can feature the optional removable wingtip. This results in a wing span of about 10.3 m (34 ft. 2 in.), short enough to fit into any “T” hangar. These removable wing tips are held in place with an automatic, quick to use locking feature. If you can’t find hangar space at your local airport, you can take the Magnus home with you. In its custom designed enclosed trailer. It only takes about 15 minutes to remove the wings and horizontal stabilizer and store them in the trailer. All the controls hook up automatically, the wings are secured by permanent wing pins under the seat pan, the horizontal stabilizer by a threaded bolt.

The wing plan-form (subtracting swept back extensions of 13,35 span version), shifts wing aerodynamic centre forward enough to accommodate C.G. travel caused by heavier engine. Short span nearly straight wing allows to achieve higher maneuvering and Vne speeds. Turbulence penetration speed to be higher. We choose this of the model name as Mingus and idea is also present that Mingus can tow gliders in the future advanced design No. 2a (engines 100hp and 120 hp) with high level efficiency and economy. Calculated speeds of the Mingus with retracted landing gear are: Vso = 64 km/h / 35 kt, Vs = 74 km/h / 40 kt, Va = 157 km/h / 85 kt, Vc econo = 245 km/h / 132 kt, Vc 75% = 278 km/h / 150 kt and Vne = 298 km/h / 161 kt. New airplane series design definition No. 3 is a long aspect ratio 17 m + / 55,8 ft + span wing motorglider forecasted for the retractable gear, smaller air cooled engine (candidates: UL Power, Wolf Hirth, Jabiru, Limbach, HKS), with the forward folding propeller, in tail-dragger configuration and with the best glide ratio of the models family with calculated glide ratio with 42 : 1 (wing including it’s span will be chosen with the target to achieve standard class gliders glide ratio’s). Carat idea and its unique systems to be transferred in to this of the Maxus two seat motorglider model! New airplane series design target No. 4 was a modern 4 seat sport aircraft using the basic Magnus fuselage shape but enlarged “in X-Y-Z directions”, means using the same as Magnus fuselage master model and Magnus advantages. Wing planed was to be complete new and tails as well, including aero-foils. Magnus cockpit width is already now of the very comfortable one with its 1255 mm / 49,4 inch. Time will show if this four seat product idea will come on the market timely to bring higher comfort, good speed and high level fuel economy as important market advantages for the pilots. Many models and ideas but it is important for the factory to follow the long term vision designing new products, and for the pilots as well to participate with their needs and wishes following factory designs! More to follow! Cabin The large (cabin width max.

As the conditions were conducive to the formation of carburettor icing, with a temperature of +5°C and a dew point of +1.6°C, particular attention was paid to the use of carburettor heat during the run-up and immediately prior to take off. The engine reportedly performed normally and carburettor heat was used during the pre-landing downwind checks and again on base leg, with its selection maintained until after the glide approach and landing, in accordance with the normal operating procedure for this aircraft.

  • Glider Handbook, Chapter 2: Components and Systems
    Chapter 2 Components and Systems Introduction Although gliders come in an array of shapes and sizes, the basic design features of most gliders are fundamentally the same. All gliders conform to the aerodynamic principles that make flight possible. When air flows over the wings of a glider, the wings produce a force called lift that allows the aircraft to stay aloft. Glider wings are designed to produce maximum lift with minimum drag. 2-1 Glider Design With each generation of new materials and development and improvements in aerodynamics, the performance of gliders The earlier gliders were made mainly of wood with metal has increased. One measure of performance is glide ratio. A fastenings, stays, and control cables. Subsequent designs glide ratio of 30:1 means that in smooth air a glider can travel led to a fuselage made of fabric-covered steel tubing forward 30 feet while only losing 1 foot of altitude. Glide glued to wood and fabric wings for lightness and strength. ratio is discussed further in Chapter 5, Glider Performance. New materials, such as carbon fiber, fiberglass, glass reinforced plastic (GRP), and Kevlar® are now being used Due to the critical role that aerodynamic efficiency plays in to developed stronger and lighter gliders. Modern gliders the performance of a glider, gliders often have aerodynamic are usually designed by computer-aided software to increase features seldom found in other aircraft. The wings of a modern performance. The first glider to use fiberglass extensively racing glider have a specially designed low-drag laminar flow was the Akaflieg Stuttgart FS-24 Phönix, which first flew airfoil.

  • USE of ELECTRIC MOTORS in the CONTEXT of GLIDER AVIATION Zastosowanie Silników Elektrycznych W Szybownictwie
    Journal of KONBiN 2021 Volume 51, Issue 2 DOI 10.2478/jok-2021-0025 Jarosław KOZUBA, Tomasz WOJNAR, Magda MROZIK, Bartosz STOŁTNY The Silesian University of Technology (Politechnika Śląska) USE OF ELECTRIC MOTORS IN THE CONTEXT OF GLIDER AVIATION Zastosowanie silników elektrycznych w szybownictwie Abstract: In sailplane aviation, I attach great importance to the achieved aerodynamic parameters due to the main idea of sailplane flights, which is the flight of a sailplane without external energy supply for staying in the air and only in favourable weather conditions, e.g. increasing thermal movements of the air. Only during take-off, external devices, such as a winch or a towing plane, can be used. Therefore, the use of a propulsion installed in sailplanes and operating only during take-off is a very convenient solution. This is a step towards facilitating the access to flying for a wider group of people due to the reduction of costs related to the take-off processes, and also increases the level of safety of sailplane flights by enabling the use of propulsion at critical moments of the flight. The study presents the current trends in the development of gliding, in particular motor gliders. Additionally, as a result of research works, the energy storage system was shown, which is the weakest element of the system, and at the same time the one with the greatest development potential.

  • A Note on Glider Electric Propulsion Francisco Leme
    A Note on Glider Electric Propulsion Francisco Leme Galv˜ao Instituto Nacional de Pesquisas Espaciais (retired) Sao˜ Jose´ dos Campos, SP, 12242-840 Brasil [email protected] Abstract This work presents the aerodynamic effects of installing a non-retractable electric regenerative propulsion system in a typical Standard Class glider. The propulsion system, including the weight for batteries and power available are estimated using a comparison with existing electric propelled gliders. The thrust available, the additional drag during free-wind milling, and the possible power extraction are estimated. This data is used to determine the performance of a glider during gliding flight, powered flight, and while regenerating electrical power. The conclusion is that a Standard Class glider with a 1.9 meter diameter two-bladed variable pitch propeller that is driven by an electrical 25 kW motor mounted in a fixed pylon, leads to a quite interesting, safe and reliable electric motor glider that is suitable for club and cross country flight training.
