We will soon start installing a modern air conditioning duct unit in the old Tupolev Tu-134. What is particularly exciting is that we will be using the aircraft’s existing ventilation system to distribute the air. This solution allows us to combine modern technology with historical substance.

The beginning of a journey

A few months ago, a group of aviation enthusiasts and technophiles were given the opportunity to help restore a decommissioned Tupolev Tu-134. Our goal is not only to preserve this historic aircraft, but also to modernize it by installing a modern ducted air conditioning unit. Thanks to the support of the Aviation Museum, where the Tupolev will later be used as an exhibition space, this ambitious project can now get underway.

The challenge

Installing a ducted air conditioning unit in an aircraft that originally had “none” is no easy task. It requires in-depth technical knowledge, creativity and a great deal of craftsmanship. Our group consists of refrigeration technicians, mechanics and aviation enthusiasts who are willing to dedicate their free time to this project.

Planning and preparation

The first step was to gather as much information as possible about the Tupolev Tu-134. We scoured technical manuals and schematics to understand the aircraft’s existing systems. It was particularly important to clarify the space requirements and power supply for the new ducted air conditioning unit.

Cooperation with the museum management

A major milestone was the contact with the museum management of the Aviation Museum. The museum management not only supports us financially, but also provides valuable resources and expert knowledge. This partnership allows us to draw on additional expertise and materials, which makes the project much easier.

The choice of air conditioning duct unit

After intensive research, we opted for an air conditioning duct unit that was specially developed for installation in ventilation ducts. These systems are compact, lightweight and meet all the necessary implementation requirements. The challenge is to integrate this modern system into the structure and electrical system of an airplane from the 1960s.

Use of the existing ventilation system

A major advantage of our project is the ability to use the aircraft’s existing ventilation system for air distribution. This approach preserves the historical substance of the aircraft. The integration of the new air conditioning duct unit into the old ventilation system requires precise planning and careful execution.

The installation

The installation process is about to begin and we are well prepared. We have already inspected the interior of the aircraft and cleared the space for the air conditioning duct unit. The brackets are ready and the wiring has been planned. Our next steps include installing the ducted unit and integrating it into the aircraft’s existing ventilation system.

Mounting the outdoor unit

The external unit of the air conditioning system is mounted in the turbine enclosure. This innovative solution enables efficient cooling and heat pump function without compromising the external appearance of the aircraft. The positioning in the turbine housing also offers the advantage that the outdoor unit is well protected and yet accessible.

Challenges and solutions

Of course, we expect challenges such as unexpected space problems and difficulties in integrating the new technology into the old structure. But through teamwork and creative thinking, we are confident that we will overcome these hurdles. The support from the museum will be a great help.

The current status

We are proud that all the preparations have been completed and the actual installation will soon begin. The first tests will show how well our planning has worked. We are looking forward to the results and to sharing our progress with you.

A look into the future

Our project shows how much can be achieved when people work together with passion and commitment. We hope that our Tupolev Tu-134 will not only remain a technical monument, but also serve as an example of how historic aircraft can be upgraded with modern technology.

We will continue to keep you up to date and report regularly on our progress. Thank you very much for your interest and support!

Stay tuned and see you next time, your Tupolev restoration team
