Gene F. Franklin. Gene F. Franklin (July 25, 1927 – August 9, 2012) was an American electrical engineer and control theorist known for his pioneering work towards the advancement of the control systems engineering – a subfield of electrical engineering. Most of his work on control theory was adapted immediately into NASA's U.S. space program, most famously in the control systems for the Apollo missions to the Moon in 1960s–1970s.

He is also noted for his authorship of influential texts on the control system, most notably, Feedback Control of Dynamic Systems, which has been translated into numerous of languages and has received literary prizes as the best book in the discipline of controls.

Early life

Franklin was born in Banner Elk in North Carolina, United States, on July 25, 1927. His father was a professor of mathematics at the local college, and his mother was a nurse, an RN at the local hospital.

Military career 
Franklin joined the United States Navy in 1945, serving in World War II, and was assigned to Navy's radar systems. He lost his enthusiasm for the navy after President Truman's decision of atomic bombings of Japanese cities of Hiroshima and Nagasaki. He took a transfer to study electronics and taught a course on electronics at the Great Lakes Naval Training Center.

Education 
Franklin took a discharge from the navy on medical grounds and joined Georgia Institute of Technology.

He received his B.S. degree in electrical engineering from the Georgia Institute of Technology in 1950, his M.S. in electrical engineering from the Massachusetts Institute of Technology in 1952, and his D.E. Sc. degree from Columbia University in 1955. 
Franklin's 1958 doctoral thesis “Sampled-Data Control Systems” (co-authored by Franklin's dissertation advisor, John R. Ragazzini) introduced digital control to a discipline which had previously operated almost exclusively in the analog domain. This breakthrough allowed control systems to become much more precise and reliable.

Teaching career 
He taught at Columbia University from 1955 to 1957 before moving to Stanford University, where he was professor emeritus of electrical engineering until his death in August 2012. His research encompassed all aspects of control incorporating digital logic, including adaptive control of both nonlinear systems and systems with multiple-data sampling. He was a recipient of the Richard E. Bellman Control Heritage Award in 2005 for "fundamental contributions to the theory and practice of digital, modern, adaptive, and multivariable control" and the John R. Ragazzini Award in 1985 for "outstanding contributions and distinguished leadership in automatic control education".

Death 
On August 9, 2012, he died at Stanford Hospital in Palo Alto at the age of 85.

Mil V-16. The Mil V-16 was a Soviet heavy cargo/transport helicopter project of the late 1960s. The Mil V-16 was designed by Mil Design Bureau, a Moscow helicopter plant. The original scheme described a heavy side-by-side twin-rotor aircraft with two Soloviev D-25VF gas turbine engines below six-bladed rotors at the tips of heavily supported wings on each side of the fuselage and tricycle-type landing gear, with both rear landing wheels mounted below the wings while the front wheel was located below the cockpit, as well as located directly under the wings.

Designed to be capable of transporting large numbers of combat units, the V-16 was also intended as a Soviet military vehicle transportation aircraft. This aircraft was one of the first for the USSR to begin using operational based algorithms within its controlling systems.

Mil Mi-20. The Mil Mi-20 was a small multipurpose transport helicopter built to replace the Mil Mi-1 in the mid-1960s. The helicopter was built for many roles, including transport, cargo, agricultural, training, and even light armed escort or gunship roles. In gunship role, it could carry Falanga or Malyutka anti-tank rockets on four to six outboard pylons, or two UB-16-57 rocket pods. 

In 1966, MVZ built a full-scale mockup of the aircraft with a 355 hp Turbomeca "Oredon-III" single-turboshaft engine and tricycle-type landing gear. Later, in 1972, MVZ built another mockup, but with a TBG-11 hp engine type and a skid undercarriage. The helicopter did not attract many customers after the second mock-up and did not replace the Mil Mi-1. Because of this, further development of the aircraft was canceled.

Mil Mi-22 (1965). The Mil Mi-22 (Cyrillic Миль Ми-22) was a 1960s Soviet project to develop a military transport helicopter. It was a development of the Mil Mi-2, but did not enter production when the Soviet military selected the Mil Mi-24 for this role instead. The Mi-22 designation which had become unused was later re-applied to a completely unrelated design, an airborne command post variant of the Mil Mi-6. This first Mi-22 concept was a Soviet attempt to create a helicopter in the Bell UH-1 class.

Design and development
In 1964, motivated by a perception that the Soviet military was losing interest in helicopters, Mil began work on improvements to the Mi-2 design, and built mockups exploring two different paths. One of these led to the development of the Mil Mi-3. The other, designated V-20 (Cyrillic В-20), was to have a fuselage stretched by inserting a plug, and equipped with a wide, sliding door. The Mi-2's three-bladed main rotor and wheeled undercarriage were to be replaced by a four-bladed rotor and skid undercarriage. Calculations showed that the Mi-2's Klimov GTD-350 engines would be insufficient for the new design, and Mil started to study a range of other gas turbines for the V-20's powerplant, including the GTD-550, GTD-10, and Glushenkov GTD-3, plus also the American Continental T65 and French Turbomeca Astazou. Rather than being an improvement of the Mi-2, the V-20 had become a practically new design.

Mil founder Mikhail Leontyevich Mil and designer Marat Nikolayevich Tishchenko unsuccessfully attempted to secure support from the Soviet Ministry of Aviation Industry to develop the design, but in 1965, the Soviet military became interested in the GTD-10 powered version of the V-20 as a helicopter capable of deploying a motorised rifle squad. The designation Mi-22 was applied at this point.

Development proceeded as far as testing the new four-bladed rotor fitted to a Mi-2 in 1971, but a complete prototype had not yet been built before the Mi-24 was selected to fulfil the same requirement in the early 1970s. In actual service, the Mi-24 was hardly ever deployed as a troop carrier, negating the purpose for which the Mi-22 had been developed.

Mil Mi-30. The Mil Mi-30 Vintoplan was a Russian tiltrotor STOL/VTOL concept that originated in 1972. The Vintoplan would have been a transport aircraft for up to 19 passengers or two tons of cargo. Its purpose was to replace the Mi-8 and Mi-17 helicopters.

Design and things 
The first tiltrotor aircraft companies were founded in the 1940s; the Vintoplan project was picked up and continued by these companies a few years after the first development. The Mil Design Bureau closely followed the tiltrotor projects at Bell Helicopters, and the concept that Bell proposed seemed to them convincing. In 1972 Mil designers initiated a similar design, the Mi-30. At the beginning of the 1980s, scientists and helicopter designers assembled a design and several layouts for this complicated aircraft, the original design of the Mil Mi-30 Vintoplan was expected to use a TV3-117 turboshaft engine with a four-bladed propeller rotor on each wing. The original design of the Mil Mi-30 had several problems: Aeroelasticity, dynamics of construction, characteristics for the converter apparatuses, aerodynamics and flight dynamics. The Vintoplan went through several different designs and layouts, shifting from having 2 engines to 3 or 4 engines and back to 2 engines.

In 1981 an issued decree on the development of the Mi-30 Vintoplan made a proposal to the customer and institutions at MAP, shortly after the military approved of the Vintoplan but desired bigger, more powerful engines. In the development the weight capacity was raised to 3–5 tons, and the passenger limit was raised to 32. In 1986–1995 the Mil Mi-30 was included in the program of armaments. However, due to the collapse of the Soviet Union and its economy, the Mil Mi-30 did not succeed in the new age of technology.

The Mi-30 Vintoplan was included in the 5-year plan in the Soviet Union from 1989 to 1995, but the project was never completed. In the last year, OKB experts in the Soviet Union designed three different models of the Mil Mi-30, each with unique designs- Mi-30S, Mi-30D, and the Mi-30L.

An unmanned tiltrotor project was started in Russia in 2015.

Air classifier. An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.

It works by injecting the material stream to be sorted into a chamber which contains a column of rising air. Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air. Due to the dependence of air drag on object size and shape, the objects in the moving air column are sorted vertically and can be separated in this manner.

Air classifiers are commonly employed in industrial processes where a large volume of mixed materials with differing physical characteristics need to be separated quickly and efficiently.  Air classifier is helpful for cement, air pollution control, food processing, pigments, pharmaceutical, cosmetics or chemical industries. One such example is in municipal recycling centers, where various types of metal, paper, and plastics arrive mixed together and need to be sorted before further processing can take place.  
  
Air classifiers can also be used as a step in the automotive recycling process.  For example, after the crushing and shredding steps, steel is removed by electromagnets, and nonferrous metals are removed by eddy-current separators.  Then an air classifier can be used to deal with the remaining dense materials (such as glass) as well as the remaining materials of various densities, most notably plastics, foams, and cloth.
