Aircraft Projects

Aircraft Projects

This section compiles all aviation-related work produced over the last several years, ranging from historical CAD restorations to modern aerodynamic analysis. The purpose of these projects is not only to recreate legacy airframes but also to explore engineering decisions, structural layouts, and aerodynamic performance characteristics through modern digital tools.

Most models presented here originate from limited archival material such as brochures, partial drawings, engineering sketches, or museum references. Each aircraft is rebuilt with accurate proportions and geometry, followed by surface checks and manufacturing-style cleanup. Some projects include CFD studies, stability observations, or structural approximations, depending on the available data.

These aircraft reconstructions represent a mixture of educational research, engineering curiosity, and digital preservation work. Many of the aircraft featured here never entered full production, making the CAD models useful for historical reference or conceptual aerodynamic study.

  • IPTN N-2130 Reconstruction — A complete 3D rebirth of Indonesia’s cancelled 100–130 seat jetliner, built from brochure data and engineering references.
  • PTDI R-2130 Reconstruction — A what-if 3D rebirth of Indonesia’s cancelled continuation of the N-2130 jetliner, built with super critical winglet, revised nose aerodynamics and revised vertical stabilizer contour data from engineering references.
  • Dassault Mercure CAD — A high-fidelity surface model of the rare Dassault Mercure, including modernized skin work and render experiments.

Engineering & Technical Models

Engineering and Technical Models Main Site

This section contains mechanical designs, prototype studies, CFD setups, and various technical models. Many of these works originate from academic projects, independent engineering experiments, or tool design for practical field work.

The focus is on real mechanical behavior, manufacturable geometry, and analysis-ready surfaces. Some items here were created to validate physical assumptions through simulation, such as flow behavior, mechanical interaction, or structural feasibility. Others are utility tools and engineering constructions that were later turned into shareable 3D models.

Over time, this repository has accumulated experimental turbine designs, precision layout tools, structural components, and general-purpose mechanical assemblies. Several models include real measurement standards and can be exported for 3D printing or further modification.

Highlights

  • Rafter Speed Square — A CAD design-based layout tool for construction and carpentry, reverse-engineered for accurate 3D printing.
  • Engineering Prototype Archive — A collection of engineering experiments and rejected research models accumulated over several years.

Research & Analysis

Research and Analysis Main Page

This section houses technical investigations, datasets, measurement logs, simulations, and analytical studies. Many of these works derive from field data collection, physics exploration, environmental measurements, or academic assignments reworked into clearer, accessible formats.

Each entry aims to provide reproducible information: detailed tables, clear methodology explanations, and computation steps when relevant. Topics range from atmospheric studies and lapse rate calculations to thermodynamic observations and applied physics. Because much of this work was originally created for academic or personal research purposes, the content here retains a scientific tone and methodological clarity.

These research notes also function as reference material for engineering or CFD projects elsewhere on the site, providing necessary inputs such as boundary conditions, measured parameters, or environmental assumptions.

Highlights

  • HX-711 Based 5 Kg Load Cell Calibration Dataset
  • MD-0550 Based Airspeed and Temperature Sensor Calibration Data with UT-363 Calibration Unit
  • Ohm Law and Kirchhoff Circuit Experiment Dataset
  • AC & RLC Circuit Analysis — Complete University Laboratory Dataset (5 Experiments)
  • Ultrasonic Sensor Calibration Dataset — HC-SR04 (Arduino + Oscilloscope Validation
  • Digital Multimeter (DMM) + PyVISA Data Acquisition & Voltage Divider Lab Dataset

Miscellaneous Projects

This section collects smaller works, creative models, experimental concepts, and various CAD files that do not fit strictly into aircraft, engineering, or research categories. Many of these items were created spontaneously—from Thingiverse-style hobby models to abandoned prototypes or early drafts of larger engineering projects.

Although diverse, these models share a common purpose: exploring ideas quickly. Some were built to test rendering techniques, modeling workflows, or mesh cleanup methods. Others represent early-stage concepts later superseded by more refined versions in other sections of the site.

This category evolves frequently as new exploratory files, artistic concept models, or unconventional experiments are added. Because of its variety, it serves as an archive of the creative and technical development process behind the more structured projects.

Highlights

  • 3D Print-Ready Drops — Community-style uploads originally prepared for Thingiverse.
  • Prototype Concepts — Early shapes and study models prior to full engineering development.
  • Render Experiments — Models used for metal-skin tests, lighting, and animation trials.

Free Community Releases (Thingiverse)

Main Free Site

A portion of the work in this section is distributed freely on Thingiverse, where I share print-ready models for the wider maker and engineering community. These uploads include small mechanical tools, aerodynamic test shapes, simple fixtures, and creative concept designs that do not require the full depth of engineering documentation found elsewhere on this site.

The goal of these free releases is to provide learning resources for students and hobbyists, while also contributing to the open-source 3D printing ecosystem. Many of these models come from experimental drafts or early prototypes that were later refined into larger projects.

All models on Thingiverse are available at no cost and can be downloaded, printed, modified, or remixed under the permissive licenses provided.
