The Hoverwing HW20 is the design of a twenty- seater ground-effect vehicle from 2008, which was developed as a speed ferry for Indonesia. The construction of a prototype should be completed in 2017. After that, the establishment of a series production in Indonesia is planned.

history

Hoverwing technology is a combination of hovercraft operation during the take-off and landing phase and ground effect operation during the normal travel phase, which is intended to reduce the high energy expenditure until the transition to the ground effect is reached, especially with larger ground effect vehicles. It was developed by Fischer Flugmechanik (FF) in the second half of the 1990s and tested between 1999 and 2001 as part of the two-seater test vehicle Fischer Hoverwing HW2VT . From the HW2VT, Hanno Fischer derived a series of designs for large-capacity ground-effect vehicles that were suitable for use in ferry services.

One of these designs was the twenty- seat Hoverwing HW20 , which the Indonesian company PT AGEC Techno was interested in in series production in 2008. Airfoil Development GmbH (AFD) in Willich was commissioned to build a prototype . The parent company of PT AGEC, the Indonesian GECAT Corporation, participated in Airfoil Development in 2009 in order to provide the necessary funds for the construction. Fischer Flugmechanik granted AFD a license for the prototype construction of the HW20 free of charge. The Airfoil Development GmbH awarded the construction of the prototype in 2010 to the Aerost structure fiber composite technology GmbH in Gundelfingen. In 2016, Airfoil Development took over the production facility of the Aero structure in Gundelfingen and has since completed the already well advanced prototype. Delivery of the HW20 prototype to PT AGEC is currently planned for the beginning of 2018.

construction

The Hoverwing HW20 has the catamaran hull known from the HW2VT , the openings of which at the bow and stern can be closed by means of an apron to create an air cushion under the hull. The inverted delta wing according to the Lippian design and the double-T tail unit were adopted from the Airfish series . The design has a takeoff weight of 9.5 tons and should be able to carry a payload of 3.5 tons. At a speed of 140 km / h, a travel time of 5 hours or a range of 900 km should be achieved. Two Walter M601D motors , each with 750 HP (552 kW), are used to drive two jacketed screws in the rear of the fuselage. Two Honda BF20 outboard motors are used for maneuvering in the harbor area.

Production and sales

The development of the Hoverwing HW20 is carried out on behalf of PT AGEC Techno in Indonesia. After the delivery of the model boat by AFD planned for 2018, the start of license production of the HW20 and marketing in Asia by PT AGEC is planned. The HW20 is offered as a passenger and cargo boat, as well as a VIP transporter. Armed military variants for coastal surveillance are also offered.

The plans for setting up a HW20 series production for the European market in Germany at Aero Struktur Maritim in Nordenham have since been abandoned.
