Mammoet Self-Propelled Modular Transporter (SPMT) https://engineers-channel.blogspot.com/p/large-machines.html A self-propelled modular transporter (SPMT) is a platform vehicle with a large array of wheels. SPMTs are used for transporting massive objects such as large bridge sections, oil refining equipment, motors and other objects that are too big or heavy for trucks. Trucks can however provide traction and braking for the SPMTs on inclines and descents.

Typhoon Class Submarine (Akula) https://engineers-channel.blogspot.com/p/submarines.html Typhoon Class Submarine is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. With a submerged displacement of 48,000 tons, the Typhoons are the largest class of submarine ever built, large enough to accommodate decent living facilities for the crew when submerged for months on end. The Russian Navy canceled its Typhoon modernization program in March 2012, stating that modernizing one Typhoon would be as expensive as building two new Borei-class submarines. With the announcement that Russia has eliminated the last SS-N-20 Sturgeon SLBMs in September 2012, the remaining Typhoons have reached the end of service. an Ohio-class SSBN was around 2 billion USD per boat.

Eurocopter Tiger and EC725 Helicopters https://engineers-channel.blogspot.com/p/helicopters.html The Eurocopter Tiger is a four-bladed, twin-engined attack helicopter which first entered service in 2003. It is manufactured by Eurocopter, the successor company to Aérospatiale's and Daimler-Benz Aerospace AG's respective helicopter divisions, which designate it as the EC 665. In Germany it is known as the Tiger; in France and Spain it is called the Tigre. Development of the Tiger started during the Cold War, and it was initially intended as an anti tank helicopter platform to be used against a Soviet ground invasion of Western Europe. During its prolonged development period the Soviet Union collapsed, but France and Germany chose to proceed with the Tiger, developing it instead as a multirole attack helicopter. It achieved operational readiness in 2008. The Eurocopter EC725 Caracal is a long-range tactical transport military helicopter developed from the Eurocopter AS532 Cougar for military use. It is a twin-engined aircraft and can carry up to 29 seated troops along with two crew, depending on customer configuration. The helicopter is marketed for troop transport, casualty evacuation, and combat search and rescue duties, and is similar to the civilian EC225.

Automated Bowling Pin Setter Machine https://engineers-channel.blogspot.com/p/how-machines-work.html In­ the early days of bowling, respotting the pins was a physically demanding job. There were actually people behind the lanes resetting the pins and sending back the balls. Today there are amazing robotic devices that do all the pin setting. The automatic pinsetter, first patented by Gottfried Schmidt, was introduced by the American Machine and Foundry Company (AMF) in 1946. This first pinsetter was a monster, weighing nearly 2 tons (1.8 metric tons) and standing 9 feet (2.7 m) tall.

Television History https://engineers-channel.blogspot.com/p/inventions.html John Logie Baird FREE (14 August 1888 -- 14 June 1946) was a Scottish scientist, engineer, innovator and inventor of the world's first television; the first publicly demonstrated colour television system; and the first purely electronic colour television picture tube. Using a Nipkow disk, Scottish inventor John Logie Baird succeeded in demonstrating the transmission of moving silhouette images in London in 1925, and of moving, monochromatic images in 1926. Baird's scanning disk produced an image of 30 lines resolution, just enough to discern a human face, from a double spiral of Photographic lenses. This demonstration by Baird is generally agreed to be the world's first true demonstration of television.

Thames Flood Barrier https://engineers-channel.blogspot.com/p/flood-barriers.html The Thames Barrier is the world's second-largest movable flood barrier (after the Oosterscheldekering in the Netherlands) and is located downstream of central London, United Kingdom. Operational since 1982, its purpose is to prevent the floodplain of all but the easternmost boroughs of Greater London from being flooded by exceptionally high tides and storm surges moving up from the North Sea. When needed, it is closed (raised) during high tide; at low tide it can be opened to enhance the river's flow towards the sea.

Kamov KA-52 Helicopter https://engineers-channel.blogspot.com/p/helicopters.html The Kamov Ka-50 "Black Shark" is a single-seat Russian attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau. It was designed in the 1980s and adopted for service in the Russian army in 1995. It is currently manufactured by the Progress company in Arsenyev. It is being used as a heavily armed scout helicopter. Kamov also designed two-seat variant, the Kamov Ka-52 "Alligator". In comparison to the original Ka-50, it has a "softer" nose profile and a radar system with two antennas—mast-mounted for aerial targets and nose-mounted for ground targets. "Samshit" day-and-night TV/thermal sighting system in two spherical turrets (one over the cockpit and the second under the nose) are also present. The Ka-52 retains the side-mounted cannon of the original Ka-50. It features six wing-mounted hardpoints as opposed to four on the Ka-50. In order to keep the weight and performance on par with that of the Ka-50, some trade-offs were introduced to the design; the scale of the armour plating and the capacity of the cannon magazine/feed have been reduced. Despite the introductions, some flight parameters have deteriorated; rate of climb is 8 m/s (vs. 10 m/s), maximum positive load factor is 3.0 g. Most of the problems were solved by installing or remotorising with new VK-2500 engine. The Ka-52 is approved for day, night and adverse.

Aswan High Dam https://engineers-channel.blogspot.com/p/dams.html The Aswan Dam, or more specifically since the 1980s, the Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. When it was completed, it was the tallest earthen dam in the world, eclipsing the United States' Chatuge Dam. Its significance largely upstaged the previous Aswan Low Dam initially completed in 1902 downstream.

Jet Engine History https://engineers-channel.blogspot.com/p/engines.html Air Commodore Sir Frank Whittle (1 June 1907 – 9 August 1996) was an English Royal Air Force air officer. He is credited with inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain who was the designer of the first operational turbojet engine.

Newspaper Offset Printer https://engineers-channel.blogspot.com/p/how-machines-work.html Offset printing is a common printing technique in which the inked image is transferred (offset) from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas.

Bucket Wheel Excavator (Bagger 293) https://engineers-channel.blogspot.com/p/large-machines.html Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They are among the largest vehicles ever constructed, and the biggest bucket-wheel excavator ever built, Bagger 293, is the largest terrestrial (land) vehicle in history by weight (14,200 tonnes), according to the Guinness Book of World Records.
