DH-1 (rocket)
The DH-1 was a circa-2005 reusable two-stage-to-orbit rocket concept proposed in the book The Rocket Company (novel), ''The Rocket Company'' by Patrick J. G. Stiennon, David M. Hoerr, Doug Birkholz (American Institute of Aeronautics and Astronautics, AIAA, 2005). The concept is described in the expired US patent 5568901. The DH-1 was never built, and its manufacturing company, AM&M, is also fictional. The book highlighted and sought to solve many problems of building a cheap reusable vehicle via the DH-1 design. ''The Rocket Company'' is a work of fiction, but the science, engineering and politics that underlies the design of the DH-1 are described as highly-feasible. The design is notable in that it attempts to avoid new or nonexistent wonder technologies, to rely on human rather than computer control, to consider the possible economics of a very small Payload (air and space craft), payload capacity (including pilot), to make use of a 'pop up first stage' launch profile, to marke ...

Airco DH
The Aircraft Manufacturing Company Limited (Airco) was an early United Kingdom, British aircraft manufacturer. Established during 1912, it grew rapidly during the First World War, referring to itself as the largest aircraft company in the world by 1918. Airco produced many thousands of aircraft for both the British and Allied military air wings throughout the war, including fighter aircraft, fighters, trainer aircraft, trainers and medium bomber, bombers. The majority of the company's aircraft were designed in-house by Airco's chief designer Geoffrey de Havilland. Airco established the first airline in the United Kingdom, Aircraft Transport and Travel Limited, which operated as a subsidiary of Airco. On 25 August 1919, it commenced the world's first regular daily international service. Following the end of the war, the company's fortunes rapidly turned sour. The interwar period was unfavourable for aircraft manufacturers largely due to a glut of surplus aircraft from the war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD DH1
The EMD DH1 was an experimental diesel-hydraulic switcher locomotive built by General Motors Electro-Motive Division in May 1951. It was powered by a pair of small diesel engines suspended under the frame, driving through a pair of Allison torque converter transmissions to the inside wheels on each truck. These inside wheels were substantially smaller than the outside wheels on each truck. One example exists in Clinton, Michigan as of 2020. Over 60 examples of a three axle DHI and its derivatives were built by Clyde Engineering in Australia and used on private railways, in particular in the sugar industry in Queensland ) , nickname = Sunshine State , image_map = Queensland in Australia.svg , map_caption = Location of Queensland in Australia , subdivision_type = Country , subdivision_name = Australia , established_title = Before federation , establishe ....

Häfeli DH-1
The Häfeli DH-1 was a 1910s Swiss two-seat reconnaissance aircraft, built by the aircraft department of the Federal Construction Works (''Eidgenoessische Konstruktionswerkstaette'', K+W) at Thun, Switzerland. Development and design In 1915 K + W set up their aircraft department and employed August Häfeli as chief engineer. Häfeli had previously designed the AGO C.I and AGO C.II, German reconnaissance biplanes. His first design was the Häfeli DH-1, similar in concept to his designs for AGO Flugzeugwerke. The DH-1 was a three-bay biplane of wood and fabric construction, it had a fuselage pod with tandem seating for the two-man crew and twin booms mounting the tail. The DH-1 was powered by an Argus As II The Argus As II was a six-cylinder, in-line, water-cooled, aircraft engine produced in Germany by Argus Motoren in 1914. The Argus As II produced at 1,350 rpm.Der Argus Flugmotor, 1916 Design and development The Argus As II was a major re ... engine built under lic ...
