The Grob G 180 SP ⁿ is a twin- engine business jet that was designed by the German manufacturer Grob Luft- und Raumfahrt . It is the world's first business jet made entirely of carbon fiber reinforced plastic . Four prototypes had been built by 2008. Since Grob Aerospace GmbH went bankrupt in August 2008, the future of the aircraft has been uncertain.

history

The first flight of the seven- to nine-seat aircraft took place on July 20, 2005 in Memmingerberg at Memmingen Airport . An intended collaboration between Grob and Pilatus Aircraft on the G 180 SP ⁿ could not be realized due to the Swiss concerns. 100 orders were placed for the aircraft. The first deliveries to customers in the USA were scheduled for 2008. For European customers, the final production and delivery should take place in St. Gallen-Altenrhein from 2009 .

The second prototype flew for the first time on September 29, 2006, but crashed after 40 flights and 28 completed flight hours on November 29, 2006 in the immediate vicinity of the factory airport , killing test pilot Gérard Guillaumaud . This prototype was equipped with the Honeywell Primus APEX intended for the series , an avionics system that enables one pilot to fly alone. In April 2010 by the Federal Bureau of Aircraft Accident Investigation released a report (AAIB), which is a fluttering of the horizontal stabilizer consequently detects and its destruction as a cause for the crash of the prototype. The cause of the flutter could not be clearly identified; However, it is recommended to "examine the construction and technical layout of the horizontal stabilizer [...] in detail" .

At the beginning of 2009, significant parts of the insolvent company were sold to H3 Aerospace GmbH & Co. KG, which continues the production of training aircraft in Grob Aircraft AG . The main creditor transferred the rights to the G 180 SP ⁿ project to Allied Aviation Technologies, the head of which is the former managing director of Grob Aerospace, Niall Olver. In March 2009 he announced a continuation of the project.

In September 2010, the company Wollen (formerly Socata) expressed an interest in taking over and developing the SP ⁿ project. The Deutsches Museum in Munich announced in June 2012 that it had received prototype No. 1 as part of a donation. The development of the SP ⁿ should also have influenced the development of the Learjet 85 , which is made entirely of composite materials and for which Grob Aerospace acted as development and production partner. After Grob Aerospace went bankrupt, this collaboration was ended in September 2008. Bombardier announced in January 2015 that the further development of the LJ 85 will be discontinued and that approx. Write off USD 1.4 billion.

The three built copies of the aircraft are D-CSPN (first prototype), D-CGSP (destroyed in a crash) and D-CSPJ.

construction

It is a low wing aircraft made from carbon fiber composite materials with swept wings that merge into winglets at the ends . The wings have flaps and spoilers . The cell consists of 110 parts and is designed for a service life of 28,000 hours, while the factory warranty is valid for seven years. Aluminum fibers have been worked into the outer layer of the outer skin, and some aluminum struts are also provided to ensure lightning protection.

The two FADEC -controlled engines are arranged on the side of the stern. Both the vertical stabilizer and the horizontal stabilizer mounted on it halfway up are indicated by arrows. A Honeywell RE100 can be installed as an APU in the rear . The aircraft is certified according to FAR 23 in the USA and CS-23 in Europe. During the design, special emphasis was placed on the possibility of take-offs and landings on short unpaved runways. The take-off distance over the standard obstacle is only 915 m.

The passenger compartment is designed as a pressurized cabin . The entrance door with a width of 84 cm and a height of 1.37 m is on the left side of the cabin. A toilet can be installed either in the rear area or opposite the entrance door. In the latter case, two folding walls are provided that separate the toilet area from both the cockpit and the cabin.
