You will be given a definition of a task first, then some input of the task.
In this task, you are given a set of context paragraph and some supporting facts to answer a question. Your task is to generate answer for given question based on set of context paragraphs and supporting facts.

Context_1 : PowerJet is a Franco-Russian 50-50 joint venture created in 2004 by aeronautical engine manufacturers Snecma (Safran) and NPO Saturn. The company is in charge of the SaM146 program the sole powerplant for the Sukhoi Superjet 100 airliner including design, production, marketing and after-sales support. It delivers a complete propulsion system, comprising engine, nacelle and equipment. Context_2 : A folding machine is a machine used primarily for the folding of paper. Paper can be folded with either a buckle or a knife; thus, there are generally three types of folding machines: buckle folders, knife folders or a combination of these two types. Whilst buckle folding is the more popular of the two methods, knife folding is sometimes preferable. Folding machine models vary in sophistication, with high-end machines capable of processing more complex folding jobs and unusual paper forms (in terms of density and size). Organizations required to undertake mass mail-out campaigns often employ folding machines to improve efficiency. Context_3 : An amusement arcade (often referred to as "video arcade" or simply "arcade") is a venue where people play arcade games such as video games, pinball machines, electro-mechanical games, redemption games, merchandisers (such as claw cranes), or coin-operated billiards or air hockey tables. In some countries, some types of arcades are also legally permitted to provide gambling machines such as slot machines or "pachinko" machines. Games are usually housed in cabinets. The term used for ancestors of these venues in the beginning of 20th century was penny arcades. Context_4 : The Sukhoi Superjet 100 (Russian: 100 ) is a modern fly-by-wire twin-engine regional jet with 8 (VIP) to 108 (all economy) passenger seats. With development initiated in 2000, the airliner was designed and spearheaded by Sukhoi, a division of the Russian civil aerospace company (UAC), in co-operation with several foreign partners. Its maiden flight was conducted on 19 May 2008. On 21 April 2011, the Superjet 100 undertook its first commercial passenger flight, on the Armavia route from Yerevan to Moscow. Context_5 : General Vincenzo Camporini, KGC, born on 21 June 1946, was the Chief of the Defence General Staff in Italy from 12 February 2008 until 2011. He became chief of staff of the Italian Air Force on 20 September 2006. Camporini has over 2,500 hours' flying time in over twenty different aircraft types, including helicopters. General Camporini is qualified in Aeronautical Sciences and International and Diplomatic Sciences. He is a Fellow of the Royal Aeronautical Society. Context_6 : Ascom B8050, usually known by the name QuickFare, is an early example of a passenger-operated railway ticket issuing system, consisting of a series of broadly identical machines installed at British railway stations from 1989 onwards. The machines allow passengers to buy the most popular types of ticket themselves, without having to go to a booking office, and are therefore useful at unstaffed, partly staffed or busy stations. All QuickFare machines have now been replaced by more modern technology. Context_7 : Trepak International AB, based in Malmo, Sweden, develops, builds, instals and supplies capping and filling machines for liquid products and labelling machines for all types of packages. The company has 25 employees and since 1981 the company has delivered more than 1000 machines. Context_8 : FalconView is a mapping system created by the Georgia Tech Research Institute. It was initially developed for the Windows family of operating systems; however, versions for Linux and mobile operating systems are under development. It displays various types of maps and geographically referenced overlays. Many types of maps are supported, but the primary ones of interest to most users are aeronautical charts, satellite images and elevation maps. FalconView also supports a large number of overlay types that can be displayed over any map background. The current overlay set is targeted toward military mission planning users and is oriented towards aviators and aviation support personnel. Context_9 : Aeronautics (from the ancient Greek words "aer", which means "air", and "nautike" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)." Context_10 : An electrostatic nuclear accelerator is one of the two main types of particle accelerators, where charged particles can be accelerated by subjection to a static high voltage potential. The static high voltage method is contrasted with the dynamic fields used in oscillating field particle accelerators. Owing to their simpler design, historically these accelerators were developed earlier. These machines are operated at lower energy than some larger oscillating field accelerators, and to the extent that the energy regime scales with the cost of these machines, in broad terms these machines are less expensive than higher energy machines, and as such they are much more common. Many universities worldwide have electrostatic accelerators for research purposes. fact_1 : PowerJet is a Franco-Russian 50-50 joint venture created in 2004 by aeronautical engine manufacturers Snecma (Safran) and NPO Saturn. fact_2 : The Sukhoi Superjet 100 (Russian: 100 ) is a modern fly-by-wire twin-engine regional jet with 8 (VIP) to 108 (all economy) passenger seats. Question: What types of aeronautical machines are described above?
Output:
jet
