Lawrance J-1, Radial 9 Engine, ca. 1922. Creator: Wright Aeronautical
Charles Lawrance, originally a race car engine designer, built his first air-cooled aircraft engine in 1921 for a Navy contract. The J-1 was the first practical American radial and satisfied a Navy need for a compact lightweight engine for use on aircraft carriers, not plagued with water leakage problems. Used in aircraft such as the Curtiss TS-1, the engine had superior performance, weighed less, and was easier to maintain than liquid-cooled engines in comparable aircraft. With encouragement from the Navy, Lawrance merged with Wright, and the J-1 developed into the famous Whirlwind series. Despite its higher initial cost relative to other engines available at the time, the Whirlwinds reliability and lower operating cost resulted in widespread use. The most famous Wright Whirlwind application was the 1927 New York-to-Paris flight of Charles Lindbergh. In 1928, Charles Lawrance was awarded the Collier Trophy for the outstanding performance of his engines based on records set in 1927

EDITORS COMMENTS
This print showcases the Lawrance J-1, Radial 9 Engine, a groundbreaking creation by Charles Lawrance in approximately 1922. Originally known for his expertise in designing race car engines, Lawrance ventured into the realm of aviation and developed this air-cooled aircraft engine to fulfill a Navy contract. The J-1 marked a significant milestone as it became the first practical American radial engine that effectively addressed the Navy's need for a compact and lightweight power source without water leakage issues commonly faced on aircraft carriers. Renowned for its exceptional performance, reduced weight, and simplified maintenance compared to liquid-cooled engines used in similar aircraft at that time, the J-1 found its application in various planes such as the Curtiss TS-1. Encouraged by the Navy's support, Lawrance merged with Wright Aeronautical, leading to further advancements in engine technology under their Whirlwind series. Despite an initially higher cost relative to other available options during that era, Whirlwinds gained immense popularity due to their unparalleled reliability and lower operating expenses. The crowning achievement of Charles Lindbergh's iconic New York-to-Paris flight in 1927 was made possible by utilizing one of these remarkable Wright Whirlwind engines. In recognition of his outstanding engineering prowess demonstrated through record-breaking performances achieved using his engines during that year, Charles Lawrance was honored with the prestigious Collier Trophy in 1928. This Heritage Images print immortalizes not only an extraordinary piece of machinery but also pays tribute to an ingenious engineer whose innovations revolutionized early aviation history.
