The Stinson SR-20 was a low-winged monoplane that was produced by the Stinson Aircraft Company from 1948 through the 1970s.
The Stinson SR20 was a small general aviation aircraft manufactured in the United States during the 1950s, 1960s, and 1970s.
The Stinson SR20 was a small general aviation aircraft manufactured in the United States during the 1950s, 1960s, and 1970s. It was designed for private use and sold to enthusiasts. It had no amenities such as heat or pressurization or even seat belts or partitioning between the front and rear seats.[1]
The main purpose of this airplane was to be able to fly around in your backyard at a low cost; however, it is still used today as an instrument trainer with many schools throughout America flying them daily along with their more expensive counterparts like Cessnas[2].
The design originated as a proposal for a single-seat low-wing monoplane by the Stinson Aircraft Company in 1946.
The design originated as a proposal for a single-seat low-wing monoplane by the Stinson Aircraft Company in 1946. It was intended to be built by that company, but when it went out of business in 1948, the design was purchased and further developed by several other companies.
Stinson aircraft were produced from 1946 through 1965, with about 3,000 examples being built altogether. The aircraft was designed to meet the requirements of FAR Part 23 rules at that time (1948), which included an empty weight limit of 2,500 pounds and a maximum gross weight of 4500 pounds; it also had a maximum speed capability of up to 160 mph (257 km/h).
A prototype designated the XP-9A first flew on September 29, 1948.
The first XF-90A prototype flew on September 29, 1948. An improved version designated the XP-9A flew on February 20, 1949. It had a redesigned nose section with stronger ribs and an additional canopy frame that was made of aluminum instead of wood.
The USAF designated this aircraft as the XC-105A and it was used for testing purposes until it was lost in a crash near Edwards Air Force Base in California in May 1949.[1]
The second XP-9B prototype (designated YF-90B) made its first flight on June 7, 1950, but was destroyed when its elevator failed after only two days at Edwards AFB.[2]
In March 1950 production of the SR-20 began for both the USAAC and USAF marked as XC-105A then farmed out to various companies for conversion as engineering development prototypes.
The SR-20 was the first aircraft produced by the Stinson Aircraft Company. It was sold to the US Army and Air Force for evaluation, but it never went into production due to problems with the landing gear.
The aircraft is an all-metal low-wing monoplane powered by a Pratt & Whitney Wasp Jr engine. The wings have a constant chord with rounded tips, which makes them aerodynamically efficient in high-speed flight but not so much at slow speeds or in strong crosswinds where they might cause drag when flying close to stall speed (stall is when there isn’t enough lift from air moving over wings).
This can cause problems for pilots who want easy landings because they must compensate by increasing power if they want their approach to be smooth; this requires more weight balanced over both engines which increases drag so landing becomes more difficult — especially if there’s no runway available nearby!
It was a simple airplane with no amenities
Stinson was a simple airplane with no amenities. It didn’t even have an air conditioning system, so the pilot had to wear a heavy jacket and gloves to keep from getting chilled. There was no radio for communication between pilots and air traffic controllers,
So if you were flying near another plane or if your engine failed midair, there would be no way for anyone else in the sky above you to help you land safely. And even though Stinson’s engines were powerful enough that they could lift this single-winged aircraft into flight with only two people aboard (one on each side), it wouldn’t fly very far before running out of fuel—so long as they landed somewhere!
The only thing that kept passengers safe during their short flights was those wonderful duralumin wings themselves: They provided plenty of lift while absorbing most impacts like bullets fired at high speeds into their vulnerable surfaces during combat missions abroad, but once those bullets hit their target zones again after firing off some distance away from where they originated…well…it didn’t matter because all that mattered now was survival itself!
Conclusion
The Stinson SR-20 was an interesting aircraft, but it was also very complicated. It was a simple airplane with no amenities, so pilots had to be careful while flying and they could expect that any maintenance would need to be done by experienced mechanics.
The Stinson SR-20 had a lot of potential as a military trainer or cargo transport aircraft, but the design never really took off due to its simplicity and lack of amenities
