Habibie H.B IX Baladewa

Greetings!😁

This time, I will introduce to you a rather unique and surprisingly mobile-friendly fictional craft. It's a fast, agile, and sturdy contra-rotating propeller-driven aerobatic plane combined with an interesting red and white paint job.

This aircraft is posted to celebrate the 77th anniversary of the Indonesian Air Force (TNI AU). Interesting right? Without further ado, please welcome, Habibie IX Baladewa!

Please note that this is a fictional craft that doesn't exist in real life in any form, such as a blueprint, prototype, and model. All design choices were either inspired by real-life existing designs or fictional designs. Anyways let's go to the description!

Description and Background 📋

Habibie H.B IX, known as Baladewa, is one of the Indonesia's greatest aerospace engineering achievements during the 20th Century. Previously, the design is constructed with a jet engine, but because Indonesia doesn't have the experience needed to construct a proper jet engine at the time, it has been chosen to build it with a turboprop engine.

To simplify the designing process, this aircraft is developed from H.B V, which doesn't go past the blueprint phase. Different from Its older brother, this aircraft is designed to be a technology demonstrator and also an aerobatic plane for the proposed "Blood Eagles" squadron.

Baladewa is powered by a local production turboprop engine named Dilona Mark VII with 6 propeller blades with a contra-rotating configuration. This new and powerful engine can produce a very high amount of shaft horsepower. However, this relatively new engine has a very large size that the plane design is basically built around the engine.

This choice makes the aircraft so much bigger than any other single-propeller aircraft. Even matching a medium bomber size! Even though the size isn't even matching the role, but the sturdy materials make the aircraft can pull high g maneuvers. Other than that, the aircraft still achieves great speed! Even around more than 700km/h on a special occasion! This made it one of the fastest single-propeller aircraft at the time. Moreover, the larger wings on the aircraft provide extraordinary flying stability even without Fly-by-Wire controls and also short-takeoff capability.

With the large fuselage design, it also provides large room for systems, cockpits, and life-support for the pilot. The large space in the canopy makes it a favorable choice for the squadron.

Available Specs

While being a plane design from the '80s, some of the plane's information is still classified by the company. However, test results during early developments are declassified and available for civilian access. Some of which are:

I. The lowest stall speed of 97 km/h

II. Max. speed on level flight ~682 km/h

III. Turn rate of 60°/s on average

IV. Roll rate of 200°/s on average

V. Lowest take-off distance is 30m

VI. Large size of 14.4m x 16.4m x 4.94m

VII. Consisted of 392 parts

Almost done, let's move to the Action Groups!

Action Groups

Every AGs on the plane is already named according to their own function. But it is better to leave a note here.

Alright, here's a list of each functional AGs and their inputs:

AG I : Main Propeller [Throttle]

AG III : Landing Lights

AG IV : Flaps [Positive Slider 1]

AG V : Signal Lights

AG VII: Smoke Trail

AG VIII: Retract Gear
