Aviastroitel AC-7
The Aviastroitel AC-7 is a Russian mid-wing, T-tailed, two seats in side-by-side configuration, glider that was designed by Vladimir Egorovich Fedorov and produced by Aviastroitel, now Glider Air Craft. It first flew in 2007. Design and development The AC-7 is derived from the AC-7M motor glider, but with a significantly redesigned fuselage. The AC-7 reduced fuselage wetted area as a result of eliminating the engine and propeller mounting space. It retains the two-seats in side-by-side configuration of the motor glider. Also revised is the complex four-wheeled fixed landing gear of the AC-7M, replaced on the AC-7 by a conventional retractable tire, pneumatic-hydraulic suspended, monowheel gear, with a lever-operated hydraulic disc brake. The aircraft's span wing employs a Wortmann FX 60-157 airfoil, mounts Fowler flaps and optional winglets. The wings are mounted to the fuselage The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main bo ...

Aviastroitel AC-7M
The Aviastroitel AC-7M is a Russian mid-wing, T-tailed, two-seats in side-by-side configuration motor glider that was designed by Vladimir Egorovich Fedorov and produced by Aviastroitel, now Glider Air Craft.Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 174. Flying Pages Europe SARL, 2015. Design and development Development of the AC-7M was started in 2002, it was first flown in 2005 and by 2006 two prototypes had been completed. The AC-7M is a conventional self-launching sailplane, but is equipped with a more powerful retractable pusher configuration Hirth F30A25A two stroke engine than is normal in these types, allowing it to be also used as a glider tug and as touring motor glider. The aircraft is capable of cruising at for while burning only of fuel. The AC-7M uses a two bladed wooden propeller of diameter. The span wing employs a Wortmann FX60-157 airfoil and mounts Fowler flaps. The wings are mounted on the fuselage w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Class AC-7
Southern Pacific Railroad's AC-7 class of cab forward steam locomotives was the fourth class of the 4-8-8-2 locomotives purchased by Southern Pacific (SP). The locomotives were built by Baldwin Locomotive Works and shared many of the same characteristics of previous AC class locomotives. The AC-7s were only slightly larger than their AC-6 predecessors, but they included larger tenders and a beveled cab front in contrast to the earlier classes' flat cab front. In the early 1940s, the majority of the class received larger cab windows of a design that would become standard with the AC-8 class. In April 1937, locomotive number 4162 was pulled aside for a series of publicity photos at SP's Sacramento, California ) , image_map = Sacramento County California Incorporated and Unincorporated areas Sacramento Highlighted.svg , mapsize = 250x200px , map_caption = Location within Sacramento C ..., shops.

USS Hector (AC-7)
USS ''Hector'' (AC-7) was a collier acquired by the United States Navy prior to World War I. She carried coal to those ships still using it as fuel to build up steam for their engines, and continued that service until her wrecking and sinking in 1916. She was the sister ship of . Construction and career ''Hector'' — the second ship to be so named by the U.S. Navy — was launched on 3 July 1909 by the Maryland Steel Company, Sparrows Point, Maryland and commissioned on 22 October 1909. She was on special service with the Atlantic Fleet from commissioning through 1913, when she was stationed at Norfolk, Virginia. From there, ''Hector'' served as a fuel ship, ferrying freight and fuel up the U.S. East Coast and down to the Caribbean, especially Guantánamo Bay and Santo Domingo. Sinking of ''Hector'' ''Hector'' was battered by winds of for 16 hours during the Charleston Hurricane of 1916 while at sea in the Atlantic Ocean off South Carolina )''Animis opibusque para ...

Utilization Categories
In electrical engineering utilization categories are defined by IEC standards and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors and relays. Definition The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions. The characteristic of the load to be switched or controlled determines the requirements for the switchgear and its correct selection for the intended application. In particular, the stress on the switching path caused by current and voltage during switching on and off is of enormous importance. For example, the switch-on and switch-off current at resistance load corresponds to the continuous operating current, while, for example, squirrel cage motors consumes multiple of t ...
