Brokaw Bullet Explained

The BJ-520 or "Bullet" was a two-seat sports airplane designed in the United States for amateur construction.

Development

Dr. Bergon Brokaw, having flown fighter aircraft in the United States Navy in the 1940s and 1950s, set out to create an aircraft with fighter-like performance and a rear seat to carry his wife "Buddy". With the help of Ernie Jones, they created a low-wing single-engine high-speed aircraft which was also stressed for aerobatic flight. After six years of development and construction, it first flew in October 1972 [1] and was considered the fastest homebuilt aircraft extant. Its tricycle undercarriage is retractable.

The Bullet originally flew with a Continental TSIO-520B turbocharged six-cylinder piston engine rated at 310hp. With that engine its top speed is listed as 219mph at sea level and 322mph at 20000feet. The name and the aircraft's registration number (N520BJ) came from the first letters of Brokaw and Jones and the 520cuin displacement of the engine.

The engine was later changed for a Lycoming TSIO-541-E1A4 turbocharged six-cylinder piston engine rated at 380hp.

Its final engine configuration was a Garrett TPE331-25AA turboprop, rated at 475hp. It is displayed with that engine at the Sun 'n Fun Museum as of 2008.

During the 1970s and 1980s, Brokaw marketed the plans to other homebuilders.

The prototype aircraft is preserved and displayed at the Sun 'n Fun air museum at Lakeland, Florida.

Only one plans-built Brokaw Bullet has been completed by builder Gene Underland. There are a few projects still in the process of being completed, but builder support is dubious since Brokaw died on 27 August 2004.
