Light Commercial Vehicle
A light commercial vehicle (LCV) in the European Union, Australia and New Zealand is a commercial carrier vehicle with a gross vehicle weight of no more than 3.5 metric tons (tonnes). The LCV designation is also occasionally used in both Canada and Ireland (where the term ''commercial van'' is more commonly used). Qualifying light commercial vehicles include pickup trucks, vans and three-wheelers – all commercially based goods or passenger carrier vehicles. The LCV concept was created as a compact truck and is usually optimised to be tough-built, have low operating costs and powerful yet fuel efficient engines, and to be used in intra-city operations.

VR Class Pr1
VR Class Pr1 (original classification N1, nickname ''Paikku'', from Finnish “paikallinen”, local) was a tank steam locomotive for local passenger services of Valtionrautatiet, Finnish railways. Ordering and delivery In the 1920s, VR was concerned about the low power and speed of their existing class Vk1-3 class locomotives that were used in local services, especially on the Helsinki commuter rail services. A decision was reached to order a new and powerful, by standards of that time, local traffic locomotive from Hanomag with the intention of licence manufacture of more units by Finnish locomotive works. At the same time, a shunting locomotive based on a similar design, VR Class Vr3, Vr3, was also ordered. The classes share many parts, including as frames, boilers and spaces for coal, but wheel arrangement, domes and top speed are very different because of their completely different roles. The locomotive was of tank design with small coal bunker in the rear, which limited ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SECR N1 Class
The SECR N1 class was a type of 3-cylinder 2-6-0 ('mogul') steam locomotive designed by Richard Maunsell for mixed traffic duties, initially on the South Eastern and Chatham Railway (SECR), and later operated for the Southern Railway (SR). The N1 was a development of the basic principles established by the Great Western Railway's (GWR) Chief Mechanical Engineer (CME) George Jackson Churchward and by Maunsell's previous N class design.Scott-Morgan (2002), p. 18 The N1 prototype was the result of modifications made to N class No. 822 during construction in 1922. The locomotive became operational in 1923 and used parts interchangeable with other Maunsell locomotive classes. The prototype N1 was the only member of the class constructed before the SECR became part of the Southern Railway at the Grouping in 1923, and featured Holcroft conjugated valve gear, Holcroft's experience in this field later aided in the development of the Gresley conjugated valve gear which ...

PRR N1s
The Pennsylvania Railroad's N1s was a class of steam locomotive built for Lines West. They were of 2-10-2 "Santa Fe" wheel arrangement, ten driving wheels with a two-wheel leading truck and a two-wheel cast KW-pattern trailing truck under a giant firebox. This arrangement was well suited to the N1s' intended purpose, which was as a heavy drag freight engine for coal and iron ore traffic to and from lakeside ports. The design was developed by the PRR's Fort Wayne Shops and orders were placed with Alco (Brooks) (35 locomotives) and Baldwin (25 locomotives) for a total of 60; the first Alco locomotive was delivered in December 1918, with the remainder arriving during 1919. The N1s was a large locomotive; the boiler was the largest then used on any non-experimental PRR locomotive, with a large Belpaire firebox with of grate area and a long combustion chamber. No feedwater heater was fitted, but a mechanical stoker and power reverse were, necessities on such a large locomotive. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNR Class N1
The Great Northern Railway (GNR) Class N1 was an 0-6-2T side tank steam locomotive designed by Henry Ivatt and introduced in 1906. They were all withdrawn from service between 1947 and 1959. None have survived. Most of the class were fitted with condensing apparatus and worked in the London area, from King's Cross and Hornsey depots, on empty coach trains, and on cross-London exchange freight trains. In 1914, Crewe Works built an armoured train An armoured train is a railway train protected with armour. Armoured trains usually include railway wagons armed with artillery, machine guns and autocannons. Some also had slits used to fire small arms from the inside of the train, a facilit ... which used a Class N1 engine. The engine was covered by a 14mm steel plate, and featured observation apertures to the front and side, closed by sliding steel shutters. Two of the Ivatt tank engines No. 1587 and No. 1590 were loaned to Crewe to be fitted with armor plating and were name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mockup
In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a ''prototype'' if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". Applications Mockups are used as design tools virtually everywhere a new product is designed. Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction. Systems engineering Mockups, wireframes and prototypes are not so cleanl ...

Northrop N-1M
The Northrop N-1M (''Northrop Model 1 Mockup''), also known by the nickname "Jeep", is a retired American experimental aircraft used in the development of the flying wing concept by Northrop Aircraft during the 1940s. Design and development Jack Northrop became involved with all-wing aircraft designs in the late-1920s, with his first flying wing research prototype being built in the 1928–1930 time period. That first prototype, registered X-216H, had evolved from earlier design studies but was not yet a true flying wing as it retained a tail unit comprising twin rudders with a single horizontal stabilizer running between them; both rudders were connected by twin booms to the thick, all-wing blended fuselage. The aircraft had an open cockpit in the center wing section and single, rear-facing, pusher propeller connected to a Menasco Cirrus inverted-four piston engine blended into the all-wing shape. X-216H was first flown in 1929 with Edward Bellande at the controls; the aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Bomber
A medium bomber is a military bomber Fixed-wing aircraft, aircraft designed to operate with medium-sized Aerial bomb, bombloads over medium Range (aeronautics), range distances; the name serves to distinguish this type from larger heavy bombers and smaller light bombers. Mediums generally carried about two tons of bombs, compared to light bombers that carried one ton, and heavies that carried four or more. The term was used prior to and during World War II, based on available parameters of Aircraft engine, engine and Aerospace engineering, aeronautical technology for bomber aircraft designs at that time. After the war, medium bombers were replaced in world air forces by more advanced and capable aircraft. History In the early 1930s many air forces were looking to modernize their existing bomber aircraft fleets, which frequently consisted of older biplanes. The new designs were typically twin-engined monoplanes, often of all-metal construction, and optimized for high enough pe ...

Flying Wing
A flying wing is a tailless fixed-wing aircraft that has no definite fuselage, with its crew, payload, fuel, and equipment housed inside the main wing structure. A flying wing may have various small protuberances such as pods, nacelles, blisters, booms, or vertical stabilizers. Similar aircraft designs, that are not technically flying wings, are sometimes casually referred to as such. These types include blended wing body aircraft and lifting body aircraft, which have a fuselage and no definite wings. A pure flying wing is theoretically the lowest drag design configuration for a fixed wing aircraft. However, because it lacks conventional stabilizing surfaces and the associated control surfaces, in its purest form the flying wing suffers from being unstable and difficult to control. The basic flying wing configuration became an object of significant study during the 1920s, often in conjunction with other tailless designs. In the Second World War, both Nazi Germany and the A ...

Northrop N-1
The Northrop N-1 (''Northrop Model 1'') was a projected flying wing medium bomber designed by Jack Northrop. Design and development The N-1 was a development of an earlier flying wing bomber concept from 1937, when Jack Northrop worked for Douglas Aircraft Company at El Segundo, California. This concept featured a fuselage that protruded forward of the leading edge of the wing, two pusher propellers, and vertical stabilizers on the tips of the wings. Its engines were never specified, but its defensive armament was to consist of a nose and tail turrets. A wind tunnel model of the concept was built and tested, but the project was abandoned shortly after Northrop left Douglas. Northrop continued work on the bomber after he formed his own company, Northrop Corporation, in 1939. In response to the United States Army Air Corps' XC-219 specification, which called for a new high-altitude medium bomber, Northrop made several major changes to the design and gave it the model number ...

Naval Aircraft Factory N-1
The Naval Aircraft Factory N-1 or Davis Gun Carrier was a 1918 maritime patrol aircraft built by the Naval Aircraft Factory (NAF), the in-house aircraft production arm of the United States Navy. A floatplane of biplane configuration with a single Liberty L-12 engine driving a pusher propeller, it was the first aircraft to be both designed and built by the NAF, and was designed to carry the Davis gun, the first recoilless gun A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "RR" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propel .... The first prototype crashed during its maiden flight due to poorly designed floats but was rebuilt. However, the aircraft's performance did not meet expectations, and navy leaders canceled the program after 2 of the 4 prototypes were subsequently damaged in serious crashes.
