Kolentang: The Indonesian Bensen-Based Autogyro
The Kolentang represents a unique chapter in Indonesian aviation history. Developed as a gyrocopter—a rotorcraft that uses an unpowered rotor in autorotation to provide lift—this aircraft showcased the nation's efforts in experimental flight and aeronautical engineering.
Development and Origins
The Kolentang was developed by the Angkatan Udara Republik Indonesia (Indonesian Air Force) through its specialized division, the Depot Penjelidikan, Pertjobaan dan Pembuatan, also known as LIPNUR. This organization focused on the research, testing, and manufacturing of aircraft to advance domestic capabilities.
Technically, the Kolentang was not an entirely original design from the ground up. Instead, it was based on the Bensen design, a popular and influential kit-built autogyro framework known for its simplicity and efficiency in providing stable, low-speed flight.

- Design Basis: Based on the Bensen autogyro design.
- Origin: Indonesia.
Technical Overview
As an autogyro, the Kolentang differs from a helicopter in that its main rotor is not powered by the engine during flight. Instead, the rotor spins due to the upward flow of air as the aircraft moves forward, a process called autorotation. Thrust is provided by a separate propeller, typically located at the rear.

Frequently Asked Questions
What is the Kolentang?
The Kolentang is an Indonesian autogyro developed by the Indonesian Air Force's research and manufacturing depot, LIPNUR.
Who manufactured the Kolentang?
It was manufactured by the Depot Penjelidikan, Pertjobaan dan Pembuatan (LIPNUR) of the Angkatan Udara Republik Indonesia.
What design was used to create the Kolentang?
The aircraft was based on the Bensen design, which is a well-known foundation for autogyro construction.
What is the difference between a gyrocopter and a helicopter?
Unlike a helicopter, a gyrocopter's main rotor is not powered by the engine during flight; it relies on autorotation for lift, while a separate propeller provides forward thrust.
What does LIPNUR stand for?
LIPNUR refers to the Depot Penjelidikan, Pertjobaan dan Pembuatan, the research, testing, and manufacturing arm of the Indonesian Air Force.
