TANNANA is a family of flying vehicles in development, designed to combine vertical take-off and landing, hovering and flexible directional control. We designed it around the Humming Propulsion System, developed over more than a decade, to open new possibilities for travel and exploration. Its capabilities and operating limits will be established through development and testing. This is the idea behind its name…
TANNANA
TANNANA CROW
Our first TANNANA
The two-seat TANNANA CROW is our first crewed model in development, intended to become the first crewed flying vehicle powered by the Humming Propulsion System. Four propulsion units, two occupants within a 200 kg target payload, and a target maximum take-off weight of one tonne
A target speed of up to 500 km/h and a range of up to 1,000 km, powered by hydrogen and batteries

Humming Propulsion
Four propulsion units are being developed to manage lift, acceleration, braking and manoeuvring by directing thrust, coordinated by the vehicle control system
- Main propulsion units
- 4
- Force direction
- Change the resultant thrust direction within the unit
The specifications shown are design targets derived from the propulsion specifications
Flight and parking scenario
The journey starts with your destination
In the intended operating concept, once you board TANNANA and enter your destination, an air traffic coordination algorithm plans the shortest available route while coordinating movement to avoid conflicts with other flight paths. TANNANA’s flexibility in low-altitude flight and hovering close to the ground offers more movement options within permitted areas and altitudes. Where air passage is unavailable, ground manoeuvring within operating areas is considered to reach a suitable stopping and parking location
We design for preparation, take-off, flight and landing, followed by manoeuvring to parking. Each stage brings operating and testing requirements into the vehicle programme
What happens after landing?
Manoeuvre to the parking space
TANNANA is being developed to manoeuvre from its landing point to suitable parking within the operating area. The path depends on its external dimensions and available manoeuvring space

Safety provisions
When we talk about flight, safety is the first concern for users and certification authorities. That is why we develop TANNANA around complementary layers of protection covering propulsion, control, energy and landing options. These systems are part of the design and development programme; testing establishes their performance and operating limits
Multiple channels within each propulsion unit
Three operating channels in each propulsion unit, each with its own motor and controller, distribute operation within the system
Multi-channel control systems
Multiple control paths are being developed to coordinate propulsion units and manage the vehicle’s response if a path fails
Primary and reserve energy
Hydrogen fuel cells work with batteries, with power and energy reserves managed for flight and landing requirements
Emergency parachute descent
Four rescue parachutes within the target design are intended to support emergency descent within altitude and speed limits established by testing
Landing on land
A target capability to land at suitable, permitted sites, accounting for space, surface conditions and operating limits
Landing on water
An additional landing option in the design, subject to validation of buoyancy, stability and water-surface conditions
Continuous system-health monitoring
Monitoring propulsion, energy and control behaviour to identify unusual indications and support an appropriate response
Fault isolation
Operating-path independence and isolation of failed components are studied to limit the spread of a fault through the system
Thrust redistribution
The control system coordinates available units and channels to support balance and manoeuvring within the remaining capability
Flight-envelope protection
Simpler user tasks alongside operating-limit monitoring, energy-reserve management and selection of a suitable landing path
Energy for the range Power for take-off
Hydrogen and batteries in one architecture, managing the demands of each phase of the journey
Power for take-off
Batteries support peak demand during take-off and manoeuvring alongside the fuel cells. Energy management coordinates demand with reserves and system health

How is this possible?
The Humming Propulsion System is the innovation that opened the way to this concept. For more than a decade, we have rethought a system that combines propulsion, lift and steering, and developed TANNANA around it
