1950s

75 YEARS OF TESTING THE FUTURE

1951---drawing-of-hypersonic-tunnel

1951

C.A.L. develops and operates a 45-foot hypersonic shock tunnel capable of 10,000 mph.

1951---Buffalo-Bill

1951

The USAF Tactical Air Command requested C.A.L to undertake a research program to improve survivability, operational safety, and weapon effectiveness of our tactical air forces. C.A.L. created the Tac-Air Projects Group, to work on program ‘Buffalo Bill.’

1952-B26

1952

C.A.L. variable stability aircraft, Beech C-45 aircraft with a 3 axis pitch, roll, and yaw system and Douglas B-26 with an initial single-axis pitch system, were used in U.S. Air Force programs. C.A.L continued to develop several generations of variable stability aircraft with increasing complexity and simulation accuracy. 

1953-fighter-intercept

1953

C.A.L. develops new computing equipment to control Navy fighter planes that successfully intercepts attacking bombers.

1953 bomber defense missile program

1953

C.A.L. researched the aerodynamic problem of controlling a missile fired with hundreds of miles per hour of backwards airspeed in the Bomber Defense Missile Program.

1953-thick-man-and-half-pint

1953

Thick Man and Half Pint were developed proportional in weight and dimensions of the average human male and six year old child respectively. They were placed inside an automobile to determine the effect of sudden decelerations on the human body.

1953-early-automobile-testing

1953

Early impact automobile testing: a car was accelerated to 20 mph, when it got to the end of a 200 foot run, a steel cable attached to the frame of the car pulled tight and the car rapidly came to a stop. 

1953-Tire-Testing-Apparatus

1953

The Full-Scale Division of C.A.L formed with the Flight Research Department and the Vehicle Dynamics Department. A tire-testing apparatus was developed for the USAF to test aircraft tires and to measure automobile tire behavior for tire manufacturers such as Dunlop, Goodrich, Goodyear, and Firestone. 

1954-Egg-crash-tests

1954

Edward Dye performed tests using eggs to represent the delicate nature of the human head. An egg was placed in a carriage that would swing back and forth like a pendulum. The carriage could be pulled backward by various distances producing different speeds and in its forward swing it would strike a concrete wall. 

1954-seatbelt-retrofit-kit

1954

Ed Dye and his fellow researchers contract with Hickok Manufacturing Company in Rochester NY for seatbelt retrofit kit installations for automobiles.

1955---simulator-terrain-avoidance-diagram

1955

USAF Tactical Air Command contract includes simulator studies for avoidance of terrain during low level navigation and attack, effects of turbulence on pilots, evaluation of radar displays, and aerodynamic limits of low-level flight. 

1955-Wind-Tunnel-most-hours

1955

4,732 hours: Calspan’s wind tunnel recorded its highest testing utilization of the era.

1955---Red-Tavern-Task

1955

An Air Force ETB-26B, serial number 44-346533 flew 50 hours from March until August in the ‘Red Tavern’ task of the Buffalo Bill program. The Air Force then provided a higher speed B-57B Canberra aircraft as the testbed, evaluating low altitude flying under automatic control and using radar and radio altimeter sensors internal to the airplane. 

1955-wave-superheater-diagram

1955

C.A.L. was issued a contract by the USAF Office of Scientific Research to build a small-scale concept facility to explore the mechanical problems and gas dynamics issues in a full-scale Wave Superheater. 

1956---early-radar-antanae

1956

C.A.L research indicated that thunderstorms, hailstorms, and snow squalls are identifiable using Doppler radar.

1956-wind-tunnel-upgrades

1956

The tunnel was changed to provide a reduced size 8' by 8' test section with perforated walls to alleviate shock waves reflecting off the walls of the test section at transonic speeds. A 13,000 HP motor was added to pull the air out of these perforations in the tunnel wall. The transonic wind tunnel was capable of testing for Mach numbers up to 1.30. A one square foot supersonic tunnel complemented the transonic tunnel by offering high-speed testing up to Mach 2.8. 

1957---Radar-for-storms

1957

C.A.L receives a contract from the U.S. Weather Bureau to develop a tornado warning device. A was successful in detecting a storm approaching in 1958.

1957-Cornell-safety-car

1957

The ‘Cornell-Liberty Mutual Safety Car’ made its public debut. Externally, this vehicle did not look much different than other cars of that era. However, the structure, as well as the interior, were quite different. Theoretically, there was nothing in the vehicle that your head could strike, no matter how violent the crash. 

1957-Perceptron

1957

Funding received for the project ‘Perceiving and Recognizing Automaton’ (PARA) at C.A.L., from the Office of Naval Research. The goal was to develop a machine, called a ‘perceptron,’ that could sense, remember, and respond like the human mind. An experimental machine, Mark I Perceptron, was developed and trained to identify patterns. This electromechanical device demonstrated an ability to learn from prior exposure to patterns. 

1958-Captive-Trajectory

1958

C.A.L. developed the first ‘Captive Trajectory Simulation’ (CTS) system to provide its wind tunnel customers with information on the aerodynamic forces and moments that result from the body, wings, and control surfaces of various airplanes, missiles, or other objects that move through the air. It is important to know how these objects dropped or jettisoned from airplanes will move after they separate. It is important to be able to predict the movement of a separated store from the carrier airplane to reduce the risk of the follow-on flight testing. 

1959--hypersonic-shock-tunnel-in-action

1959

A 3-foot square test section shock tunnel, capable of testing from Mach 5 to 10 is built.

1959-wave-superheater-construction

1959

Construction of the full scale facility on the Genesee Street campus was initiated. A concrete block main building with the first floor underground was built to contain the rotor, drive motor, pebble heaters, gas nozzles, associated plumbing, and a control room. Two large spheres were constructed as containment vessels for the helium driver gas.
