Warren CP-1
The Warren CP-1, also called Miss Poly, Miss Polytechnic and the Warren Monoplane, was the second aircraft built by engineering students at California Polytechnic State University, California Polytechnic College, after their first project the Mason Greater Meteor. Design and development The CP-1 was built for Cal Poly instructor Martin C. Martinsen and completed in August 1929. It was a high-wing conventional landing gear equipped monoplane using dual airfoil-shaped lift struts. The fuselage is made of fabric-covered welded steel tubing, with wooden wing spars and ribs. The red, yellow and blue paint scheme was taken a from an earlier Berrylold Paint advertisement. An exhaust collector ring, larger rudder and low-pressure wheels and tires were added after construction. Operational history The CP-1 was licensed as an experimental aircraft and test flown from E.W. Clark Field in September 1929. It won a silver cup and two blue ribbons at the California State Fair, and on 29 June 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California State Fair
The California State Fair is the annual state fair for the state of California. The fair is held at Cal Expo in Sacramento, California. The Fair is a 17-day event showcasing California's industries, agriculture, and diversity of people. The CSF features blue-ribbon animal displays, culinary delights and competitions, live music concerts, a carnival, fireworks, and other family fun. In 2018, officials reported daily attendance drew between 20,000 and 60,000 people per day and about $8.5 million of food and beverage expenditures. The fair is policed by the California Exposition and State Fair Police. The Covid-19 pandemic caused losses of around $16 million in revenue and impacted over 800 seasonal workers. Cal Expo is now a temporary Covid-19 testing site, homeless trailer site, and a go-to partner during the state's battle with wildfires. History According to an editorial in the Daily Alta on November 5, 1850, fairs were common on the east coast of the United States. They beli ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Harlow PJC-1
The Harlow PJC-2 was a 1930s American four-seat cabin monoplane, designed by Max Harlow. Development Max Harlow was an aeronautical engineer and instructor at the Pasadena Junior College. Under his tutelage, the aircraft designated PJC-1 was designed and built as a class project. The PJC-1 first flew on 14 September 1937 at Alhambra, California but it crashed during an extended (more than six turn) spin test with the center of gravity ballasted to the aft limit, as it was going through the certification process—a problem generally laid at the feet the unusually rigorous spin test requirement and the government test pilot, who bailed out of the airplane after the spin "flattened out." The airplane struck the ground, still in the "flat" (longitudinally level) attitude in a bean field near Mines Field (now Los Angeles International Airport) with considerable damage; although repairable, the PJC-1 was never returned to service. PJC students then built a slightly modified airpla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren CP-2
The Warren CP-2, also called the Warren Taperwing, or the Kinner Taperwing was the third and last aircraft built by engineering students at California Polytechnic College in the 1930s Design The aircraft is a side-by-side open cockpit biplane with conventional landing gear, powered by a Kinner K-5 radial engine. The wings used wooden spars and ribs with fabric covering. The fuel tank is mounted against the firewall. The fuselage was acquired from the liquidation of Arrow Aircraft in Lincoln, Nebraska. Operational history The aircraft was registered in the experimental category and several attempts were made to register it in the restricted category for aerial photography. New owner Clifford Bryant flew the aircraft from Fresno, California until a partial motor mount failure caused the engine to nearly fall off in flight. The aircraft was sold to Madonna Inn The Madonna Inn is a motel in San Luis Obispo, California. Opened for business in 1958, it quickly became a landmark ...

Comet 7D
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several milli ...

Clark Y
Clark Y is the name of a particular airfoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in 1922 by Virginius E. Clark using thickness distribution of the German-developed Goettingen 398 airfoil.Piccirillo, Albert, "The Clark Y Airfoil - A Historical Retrospective," SAE/AIAA paper 2000-01-5517, presented at the World Aviation Congress & Exposition, October 10, 2000, San Diego, California. The airfoil has a thickness of 11.7 percent and is flat on the lower surface aft of 30 percent of chord. The flat bottom simplifies angle measurements on propellers, and makes for easy construction of wings. For many applications the Clark Y has been an adequate airfoil section; it gives reasonable overall performance in respect of its lift-to-drag ratio, and has gentle and relatively benign stall characteristics. But the flat lower surface is not optimal from an aerodynamic perspective, and it is rarely used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lift Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more imp ...
