The aircraft is capable of both unassisted take-off and periods of powered flight — as may be necessary to sustain soaring flight. The highly efficient 22kW brushless electric motor installed in the nose is powered from two purpose built rechargeable Lithium battery packs and drives a folding propeller. The power chain is aerodynamically clean and operationally very simple compared to a retractable power plant. It is also effectively maintenance free.

There is no forward pitch moment on take-off and the motor delivers the same performance regardless of altitude. Two purpose built Lithium battery packs, with built-in Battery Management System and a combined capacity of 4.

Weighing just over 15kg each they are easily removed for charging. Designed for the new FAI All control linkages are automatic; rigging could not be easier! With a maximum take of weight MTOW of kg or ,5 kg if equipped with the optional ballistic recovery system and a stall speed of less than 65 kph 35 kts the aircraft is de-regulated in terms of air worthiness in most countries.

The glider is trimmed in pitch via an innovative variable-position horizontal stabiliser. The incidence of the horizontal stabiliser is governed by the flaperon setting; the five settings of the flap control produce corresponding changes in the incidence of the stabiliser, thus defining the trim airspeed in relation to the flap setting while the conventional elevator minimizes trim drag.

Thanks to the near full span flaperonsthe SILENT 2 Electro soars effortlessly, even in the lightest air yet penetrates well, while the highly innovative drive chain delivers clean and efficient power — at the turn of a knob. The aircraft is a delight fly! The weight of motor could be only about 7kg so that 30kg of batteries could compensate a nose-heavy moment. But its construction needed to be strong enough and suitable for installation.

Controller is mounted on a cooling rib on top of main wheel box, and is cooled by three ventilators. To read the motor manual click here. It fits into standard hole of 57mm diameter. It is equipped with sunlight readable high resolution colour display.

The screen is really bright, in fact brighter than most displays, and is readable in the strongest of sunshine! In case that one of the parameters is out of limit, alarm is activated together with sound signal. FCU also count total engine running time, and some other parameters. There is only one switch to turn ON instrument and a knob with rotary encoder which acts as throttle and propeller brake.

Discus 2c deluxe

Second glider in my glider series. The glider flies really stable with the engine off, with engine on it tends to lift the nose. Enigne performance is better and faster than the Arcus M i made, but glide ratio is worse.

Beware during takeoff to not lift the tail so much, there aren't a lot of room for the propeller to move on. Like last time i still don't know how to color canopy's, so if you know how please tell me. Also leave a suggestion if you wish for me to build a glider.

CaesiciusPlanes You can get versions of gliders that has either jets, props, or electrical engines. If they aren't able to find any lift they use these engines to fly back home.

Often these engines are built in the plane fuselage, and then lifted out if needed. My plane here has a front engine sustainer that is a electrical motor with propellors that fold to the side.

Discus – 2c FES sailplane

No Upvotes. Log in to upvote.It replaced the highly successful Schempp-Hirth Discus. In plan view is the almost crescent shape of the leading edge is similar to the Discus but is tapered in three stages. An entirely new wing section is used. The dihedral towards the tips was greatly increased compared with the Discus. Winglets are an optional extra. A version with a narrow fuselage is called the Discus-2a and the wider fuselage version is called the 2b.

The fuselage was specifically designed to be highly crash resistant. The Discus-2 has also been successful though the competition from the Rolladen-Schneider LS8 and the Alexander Schleicher ASW 28 has meant that the Discus-2 has not sold in such great numbers as its predecessor, which went unchallenged for many years.

A version with an metre span, with the option of smaller wing tips to fly as a Standard Class glider, was launched in and designated Discus-2c. It uses material from the Wikipedia article " Schempp-Hirth Discus-2 ".

Except where otherwise indicated, Everything. Cookie policy. You are here Everything Explained. Design and development In plan view is the almost crescent shape of the leading edge is similar to the Discus but is tapered in three stages. Discus-2c Production variant with 15 metre or 18 metre wingspan. Discus-2cT "Turbo" variant with 15 metre or 18 metre wingspan and a Discus-2c FES Production variant with 15 metre or 18 metre wingspan equipped with a front electric sustainer.

Web site: Archived copy.Discus 2c FES18m without flaps, perfect choice for aeroclubs and recreational pilots. Certified by EASA in So for used sailplane we do not offer retrofit, except in some special cases. Unfortunately EASA do not consider so called "Experimental registration" like is arranged in US, but only exceptions are possible as Annex II types, which are then under responsibility of national aviation authorities.

Most important data is maximum weight of non lifting parts for specific sailplane weight of everything including pilot, except the wings. It must have enough reserve for additional 45kg of weight in the fuselage. Most of the sailplanes which were designed to fly with some kind of engine, can be also FES equipped!

It this requirement is not met, than is unfortunatelly not possible to install FES due to safety reasons. Nose section should be round as possible. It could be also slightly elliptic or eggy shape, but not too much. For most types of sailplanes we could find a solution with special spinner or if this would be not possible we could adjust front part of fuselage so that shape would become more appropriate.

Here is rough explanation of procedures which are possible in European countries under currently valid EASA regulation regarding development and certification of new products.

When sailplane is modified CoA is not valid anymore, and next options are available to become airworthy again:. So we cooperate with other companies, and sailplane manufacturers which are usually certified as ADOA. Unfortunately EASA do not have yet available suitable procedures so that we could be actually able to arrange RSTC for different types of sailplanes, without cooperation of Type Certificate holder. This mean FES system would be certified as part of the sailplane. National Permit to fly can be issued, if accepted by local CAA.

Certification is arranged according local regulations if it is required. Please check EASA fees and charges in order to understand costs involved in certification!

Additionally each sailplane type has some specific features, which requires different parts and arrangements, which we must developed first. In order to be legal to use your newly FES equipped sailplane, installation should be done by regulations and conditions as required by local regulations.

As you can see it is quite difficult to fulfil all this requirements, and it is questionable if at the end you would spend less money in your own project. For all this reasons we would like to encourage you, to order a new FES equipped sailplane from a list of available new FES equipped sailplanes as above! Airworthiness Here is rough explanation of procedures which are possible in European countries under currently valid EASA regulation regarding development and certification of new products.

Price of FES installation Depends on: -is single or double seater sailplane? Is FES available as a kit? Installation of FES is quite demanding job which can not be done in a few days as you might imagine. It requires structural modifications of fuselage, mechanical and electrical installation.

All this require certain skills and experiences. For proper and safe installation, some special tools and equipment is required. LZ design d.Thanks to the perfect control balance and the harmonic gliding characteristics, you'll feel comfortable and relaxed the first moment you'll fly a Discus-2c.

With the proven electrical FES Front Electric Sustainer system built by LZ Design, the Discus-2c now also has an option for an innovative, environment-friendly sustainer system that is very different from all former systems. The reliable and lighting-fast starting and stopping of the engine with any noticeable additional drag allows to spontaneously use the electrical engine, which opens completely new perspectives.

The powered flight is perceived in a very new way and can be enjoyed by puristic glider pilots. With 18 meters wing span and more than one additional meter of wing area compared to the Standard Class version, the Discus-2c can be flown at very low wing loads and above-average climbing performance, despite the slightly higher empty weight due to the FES system.

Operation is extremely simple: Just toggle a switch and adjust the engine power with a rotary switch. This is all it take to gain height at almost no vibration and minimal engine noise. Operating mistakes are practically impossible and the pilot's attention remains available for other flight decisions. Switching off the engine, the propeller will automatically stop in the defined end position and the blades will fold onto the fuselage.

The powered aeroplane has become a glider within seconds. The foldable propeller is located at the tip of the fuselage. The blades fold tightly onto the fuselage when not in use. Two 16 kg batteries are safely stowed in a compartment behind the wings in the fuselage, can be reached from above and easily taken out for charging. Deliberately abandoning extraction and retraction of the engine saves complex components - and valuable time when engine help is needed.

The long tradition of the Discus as the leading Standard Class glider has been taken over and deepened by the Discus While continuously reaching top positions at World Championships, European Championships and Nationals, its pleasant handling has also made it popular as an all-round glider. Get Home Electrically. Simple and easy - and thus safe. Clever Design.
