The Lockheed C-130 Hercules is an American four-engine turboprop military transport aircraft designed and built originally by Lockheed.


Lockheed C-130H Hercules

Design/Development

The Hercules resembled a larger four-engine brother to the C-123 Provider with a similar wing and cargo ramp layout that evolved from the Chase XCG-20 Avitruc, which in turn, was first designed and flown as a cargo glider in 1947.[5] The Boeing C-97 Stratofreighter also had a rear ramp, which made it possible to drive vehicles onto the plane (also possible with forward ramp on a C-124). The ramp on the Hercules was also used to airdrop cargo, which included low-altitude extraction for Sheridan tanks and even dropping large improvised "daisy cutter" bombs.

 

The new Lockheed cargo plane design possessed a range of 1,100 nmi (1,270 mi; 2,040 km), takeoff capability from short and unprepared strips, and the ability to fly with one engine shut down. Fairchild, North American, Martin, and Northrop declined to participate. The remaining five companies tendered a total of ten designs: Lockheed two, Boeing one, Chase three, Douglas three, and Airlifts Inc. one. The contest was a close affair between the lighter of the two Lockheed (preliminary project designation L-206) proposals and a four-turboprop Douglas design.

The Lockheed design team was led by Willis Hawkins, starting with a 130-page proposal for the Lockheed L-206.[6] Hall Hibbard, Lockheed vice president and chief engineer, saw the proposal and directed it to Kelly Johnson, who did not care for the low-speed, unarmed aircraft, and remarked, "If you sign that letter, you will destroy the Lockheed Company."Both Hibbard and Johnson signed the proposal and the company won the contract for the now-designated Model 82 on 2 July 1951.

 

The first flight of the YC-130 prototype was made on 23 August 1954 from the Lockheed plant in Burbank, California. The aircraft, serial number 53-3397, was the second prototype, but the first of the two to fly. The YC-130 was piloted by Stanley Beltz and Roy Wimmer on its 61-minute flight to Edwards Air Force Base; Jack Real and Dick Stanton served as flight engineers. Kelly Johnson flew chase in a Lockheed P2V Neptune

The C-130B model was developed to complement the A-models that had previously been delivered, and incorporated new features, particularly increased fuel capacity in the form of auxiliary tanks built into the center wing section and an AC electrical system. Four-bladed Hamilton Standard propellers replaced the Aeroproducts three-blade propellers that distinguished the earlier A-models. The C-130B had ailerons with boost increased from 2,050 psi (14.1 MPa) to 3,000 psi (21 MPa), as well as uprated engines and four-blade propellers that were standard until the J-model's introduction.

The C-130 entered service with the U.S. in 1956, followed by Australia and many other nations. During its years of service, the Hercules family has participated in numerous military, civilian and humanitarian aid operations. In 2007, the C-130 became the fifth aircraft to mark 50 years of continuous service with its original primary customer, which for the C-130 is the United States Air Force. The C-130 Hercules is the longest continuously produced military aircraft at over 60 years, with the updated Lockheed Martin C-130J Super Hercules currently being produced.
