Convair XP5Y
The Convair R3Y Tradewind was an American 1950s turboprop-powered flying boat designed and built by Convair. Design and development Convair received a request from the United States Navy in 1945 for the design of a large flying boat using new technology developed during World War II, especially the laminar flow wing and still-developing turboprop technology. Their response was the Model 117. It was a large high-wing flying boat with Allison T40 engines driving six-bladed contra-rotating propellers. It had a sleek body with a single-step hull and a slender high-lift wing with fixed floats. The Navy ordered two prototypes on 27 May 1946. Designated XP5Y-1, the first aircraft first flew on 18 April 1950 at San Diego. In August the aircraft set a turboprop endurance record of eight hours six minutes. The Navy decided not to proceed with the patrol boat version, instead directing that the design should be developed into a passenger and cargo aircraft. One of the XP5Y-1 prototypes was ...

Naval Air Station Alameda
Naval Air Station Alameda (NAS Alameda) was a United States Navy Naval Air Station mostly in Alameda, California, with a slight portion of it within San Francisco proper, on San Francisco Bay. NAS Alameda had two runways: 13–31 measuring and 07-25 measuring . Two helicopter pads and a control tower were also part of the facilities. History In 1927, wetlands at the west end of Alameda Island on the east shore of San Francisco Bay were filled to form an airport (Alameda Airport) with an east–west runway, three hangars, an administration building, and a yacht harbor. The airport site included the Alameda Terminal of the First transcontinental railroad (California Historical Landmark #440). By 1930, United States Army Air Corps operations referred to the site as Benton Field. Pan American World Airways used the yacht harbor as the California terminal for '' China Clipper'' trans-Pacific flights beginning in 1935. The ''China Clipper'' terminal is designated California Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflight Refueling
Aerial refueling (American English, en-us), or aerial refuelling (British English, en-gb), also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the List of tanker aircraft, tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are ''#Probe-and-drogue, probe-and-drogue'', which is simpler to adapt to existing aircraft and the ''#Flying boom, flying boom'', which offers faster fuel transfer, but requires a dedicated Boom operator (military), boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or Loiter (aeronautics), loiter time. A series of air refuelings can give range limited only by crew Fatigue testing, fatigue/physical needs and engineering factors such as engine oil consumption. Because the receiver aircraft is topped-off with extra fuel in the air, air re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin JRM Mars
The Martin JRM Mars is a large, four-engined Cargo aircraft, cargo transport flying boat designed and built by the Glenn L. Martin Company, Martin Company for the United States Navy during World War II. It was the largest Allies of World War II, Allied flying boat to enter production, although only seven were built. The United States Navy contracted the development of the XPB2M-1 Mars in 1938 as a long-range Maritime patrol aircraft, ocean patrol flying boat, which later entered production as the JRM Mars long-range transport. Four of the surviving aircraft were later converted for civilian use to Aerial firefighting, firefighting water bombers. Two of the aircraft remained based at Sproat Lake just outside of Port Alberni, British Columbia, Canada, with one, ''Hawaii Mars'', remaining in operation until 2016. The British Columbia Aviation Museum acquired ''Hawaii Mars'' and it was flown there in 2024. The same year it was announced that ''Philippine Mars'' would be acquired by ...

Maximum Takeoff Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. It refers to the maximum permissible aircraft weight at the start of the takeoff run. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or the length of the runway to be used for takeoff or landing. Maximum permissible takeoff weight or "regulated takeoff weight", varies according to flap setting, altitude, air temperature, length of runway and other factors. It is different from one takeof ...

Allison T40-A-10
The Allison T40, company designation Allison Model 500, was an early American turboprop engine composed of two Allison T38 power sections driving a contra-rotating propeller via a common gearbox. Design and development The T40 concept originated at Allison in 1944, where design studies were carried out on a turboprop engine. Taking advantage of this effort, the US Navy awarded Allison a contract for the design and development of a turboprop engine. The resulting T40 combined two Allison T38-A-1 power sections side-by-side with a common reduction gearbox powering contra-rotating propellers. Similar in layout to the Armstrong Siddeley Double Mamba, the T40 differed in that each engine drove both the forward and the rear propellers, unlike the Double Mamba, where each Mamba power section drove either the front or the rear propeller separately. The T38-A-1 power sections each contained 17-stage compressors giving a pressure ratio of 6.3:1, eight combustion chambers, and four-sta ...

NACA Airfoil
The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum Camber (aerodynamics), camber as percentage of the Chord (aircraft), chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thick ...

Passenger
A passenger is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, cars, passenger trains, airliners, ships, ferryboats, personal watercraft, all terrain vehicles, snowmobiles, and other methods of transportation. Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business. Legal status In most jurisdictions, laws have been enacted that dictate the legal obligations of the owner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convair XP5Y-1 3-view Line Drawing
Convair, previously Consolidated Vultee Aircraft Corporation, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history. Convair is best known for its military aircraft; it produced aircraft such as the Convair B-36 Peacemaker and Convair B-58 Hustler strategic bombers, and the Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. It also manufactured the first Atlas rockets, including the rockets that were used for the crewed orbital flights of Project Mercury. The company's subsequent Atlas-Centaur design continued this success and derivatives of the design remain in use as of 2025. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller than contempo ...

Grumman F-9 Cougar
The Grumman F9F/F-9 Cougar is a carrier-based jet propulsion, jet-powered fighter aircraft designed and produced by the American aircraft manufacturer Grumman. It was developed during the early 1950s on behalf of the United States Navy (US Navy) and United States Marine Corps (USMC), which were keen to quickly introduce a naval fighter equipped with a swept wing. Grumman's design team decided to adapt its earlier Grumman F9F Panther, F9F Panther, replacing the straight wing of the Panther with a new swept wing. Thrust was also increased with the installation of a newer and more powerful engine. Nevertheless, the aircraft remained limited to subsonic speeds. The first prototype (XF9F-6), which was produced by modifying an existing Panther, performed its maiden flight on 20 September 1951. The Navy considered the Cougar to be an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6. During December 1952, the F9F-6 was in ...
