Redditor Reveals How Engineers Made Use of "Chicken Gun" to Fire Bird Carcasses at Aircraft Components Just to Test Plane Safety
A large-diameter compressed-air gun known as a "chicken gun" or "flight impact simulator" is used to shoot bird carcasses at aircraft parts to imitate high-speed bird strikes while the aircraft is in flight. The most frequent targets in such testing are jet engines and airplane windshields, as they are particularly susceptible to damage from such impacts.
Although several bird species are employed in the testing and certification of airplanes, the device earned the nickname "chicken gun" since chickens are the most frequently utilized "ammunition" due to their easy accessibility. The U.S. Civil Aeronautics Administration and the Westinghouse Electric and Manufacturing Company collaborated to create the first chicken cannon in 1942.
It was developed by Westinghouse's High Power Laboratory in Pittsburgh and had a muzzle velocity of up to 270 mph (430 km/h), although it could fire bird carcasses at a maximum speed of 400 mph (640 km/h). The gun's propellant was compressed air, which was stored in an accumulator by a compressor until the appropriate pressure was attained.
An electric quick-release valve was opened by an operator to fire the gun, releasing compressed air into the barrel. Various muzzle velocities could be achieved by adjusting the pressure maintained in the accumulator.
Up until November 1943, the gun was in operation at the High Power Laboratory. It was relocated to the Indianapolis Experimental Station, a CAA research and development facility in Indianapolis, in early 1945.

A Chicken Gun is a compressed air cannon that fires bird carcasses
There, it was used to test parts for several commercial aircraft manufacturers before being retired sometime in 1947. The De Havilland Aircraft Company in the United Kingdom independently created a similar gun in the mid-1950s.

World War 3 and World War 4
The use of the "chicken gun" in aviation safety testing highlights a significant commitment to ensuring the resilience of aircraft components against real-world impacts. By simulating high-speed bird strikes, engineers are able to rigorously assess critical parts such as jet engines and windshields. This innovative approach not only prioritizes passenger safety but also embodies the ethical responsibility of the aviation industry to develop and implement effective safety protocols.
As advancements in technology continue, the reliance on such testing methods will remain essential in addressing the challenges posed by wildlife encounters in flight. The implications of these tests extend beyond compliance; they reflect a proactive stance in safeguarding lives and enhancing the overall integrity of aircraft design.

The UK's Royal Aircraft Establishment constructed a chicken gun in 1961. This cannon was frequently used until 2016 when it was transferred to the Canada Aviation and Space Museum, and two more contemporary weapons took its place.
The use of a modular barrel allows the replacements to more easily accommodate birds of various sizes.

The use of the "chicken gun" in aviation safety testing brings to light critical ethical concerns surrounding animal use in research. While the primary objective is to enhance safety by simulating bird strikes on vital aircraft components, such as jet engines and windshields, the underlying implications of using animal carcasses cannot be overlooked. The aviation industry must navigate this complex terrain, ensuring that the drive for safety does not come at the cost of ethical responsibility.
As discussions around these practices unfold, it is essential for the industry to maintain transparency and align testing methods with broader societal values. This ongoing dialogue can foster a more informed public and encourage accountability, ultimately leading to practices that respect both safety and ethical standards.
