Joint Stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In t ...

Hongdu L-15
The Hongdu JL-10, also initially known as Hongdu L-15 Falcon, is a supersonic advanced jet trainer and light combat aircraft developed by Hongdu Aviation Industry Corporation (HAIC). It is used by the People's Liberation Army Air Force (PLAAF) as a lead-in fighter trainer (LIFT). Development China Aviation Industry Corporation II (AVIC II) was working toward a new advanced trainer for the People's Liberation Army (PLA) by 2000; that year AVIC II contracted the Yakovlev Design Bureau from Russia — and designer of the Yak-130 trainer — as a technical and scientific consultant for the L-15 programme. The L-15 would compete with the Guizhou JL-9 developed in parallel by China Aviation Industry Corporation I. The prototype was completed in September 2005 and first flew on March 13, 2006. The initial variants were a subsonic advanced jet trainer and a supersonic advanced fighter trainer. Development of the L-15B, a supersonic variant for LIFT, was announced in 2010. It first fle ...

Manufacturing Companies Established In 1919
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. T ...

Aircraft Manufacturers Of The Czech Republic And Czechoslovakia
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Cessna 550
The Cessna Citation II are light corporate jets built by Cessna as part of the Citation family. Stretched from the Citation I, the Model 550 was announced in September 1976, first flew on January 31, 1977, and was certified in March 1978. The II/SP is a single pilot version, the improved S/II first flew on February 14, 1984 and the Citation Bravo, a stretched S/II with new avionics and more powerful P&WC PW530A turbofans, first flew on April 25, 1995. The United States Navy adopted a version of the S/II as the T-47A. Production ceased in 2006 after of all variants were delivered. Design and development The Citation II (Model 550) was developed to provide the samw docile low-speed handling and good short-field performance as the preceding Citation I while addressing a primary criticism of that aircraft — its relatively slow cruise speed of around at altitude. The II stretches the Citation I fuselage by 1.14m (3 ft 9in), increasing seating capacity to ten (two pilot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eclipse 500
The Eclipse 500 (model EA500) is a very light jet (VLJ) originally produced by Eclipse Aviation of Albuquerque, New Mexico, United States. The company was founded in 1998 to develop the 1997 Williams V-Jet II demonstrator. The prototype first flew with Williams EJ22 turbofans on August 26, 2002.

Pilatus PC-12
The Pilatus PC-12 is a pressurized, single-engined, turboprop aircraft, manufactured by Pilatus Aircraft of Stans, Switzerland, since 1991. It was designed as a high-performance utility aircraft that incorporates a large aft cargo door in addition to the main passenger door. Due to its efficient, high-utility design, the PC-12 is used by a large variety of operators. The main use for the aircraft is corporate transportation, but it is also used by fractional and small regional airlines, air-ambulance operators, and many government agencies, such as police departments and armed forces. The PC-12 has been the best-selling pressurized, single-engined, turbine-powered aircraft in the world for several consecutive years, with 1,800 deliveries made as of April 2021. Development In October 1989, Pilatus announced the development of the PC-12 at the annual convention of the National Business Aviation Association (NBAA).

Pilatus PC-21
The Pilatus PC-21 is a turboprop-powered advanced trainer with a stepped tandem cockpit. It is manufactured by Pilatus Aircraft of Switzerland. Development In November 1997 Pilatus flew a modified PC-7 Mk.II in order to test improvements for a prospective next generation turboprop trainer. As a result of these tests, Pilatus elected to fund the development of a new training system in November 1998; development of the new trainer, designated as the ''PC-21'', formally started in January 1999. The PC-21 would be developed and certified as a completely new training system, aimed at meeting future military customers' specifications in terms of capability and life-cycle costs for the next three decades. A key aim for the PC-21 was to allow jet aircraft pilots to perform the majority of their training using the type before converting to jet-powered types, allowing operators to make substantial savings. In order to achieve this aim, the new trainer was required to have an expanded pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pitts Special
The Pitts Special (company designations S-1 and S-2) is a series of light aerobatic biplanes designed by Curtis Pitts. It has accumulated many competition wins since its first flight in 1944. The Pitts biplanes dominated world aerobatic competition in the 1960s and 1970s and, even today, remain potent competition aircraft in the lower categories.Montgomery and Foster 1992, p. 92."Plane and Pilot" 1977, p. 84. Design and development Curtis Pitts began the design of a single-seat aerobatic biplane in 1943–1944.Taylor 1980, p. 899. The design has been refined continuously since the prototype first flew in September 1944; however, the current Pitts S-2 still remains quite close to the original in concept and in design. Several of the aircraft that Curtis Pitts built had a picture of a skunk on them and were called "Stinkers". After she bought it, aerobatic performer Betty Skelton called the second aircraft that Curtis built, "Little Stinker". The prototype S-2, wh ...
