Flying turbojet platform for paramedics

Since I was already inundated with news that British paramedics use jetpack, I will post a short description of last year’s project.

In October 2019, the CopterHack hackathon was held in Moscow, where I decided to visit with my turbojet engines with the hope of hunting a couple of smart, young and promising engineers. At first, the “youth” reacted violently to the jetpack, and then said: “Damn, you need to do this, six months or more, and we want to win the hackathon, we won’t help you.”

As a result, in 2 days we made a dimensional model of a hybrid (turbojet-impeller) rescue vehicle for emergency evacuation in hard-to-reach areas. The jury was twisted at the temple.

I invite you to get acquainted with slides and options for ideas and discuss the possibilities of rescue systems in the comments.

subscribe to the channel Jetpack school to train pilots and jetpack engineers.

Since many were generally “not in the subject” that turbojet platforms exist, I had to tell and convince by the example of foreign colleagues.

Aircraft of the French, Swiss and NASA.

The first working prototype that we launched in front of the American Embassy in October 2018.

At the time of the hackathon, we no longer had 2 engines with a thrust of 18 kg, but 2 engines with a thrust of 30 kg each, they decided to take them as a basis for creating a “cruising battery”.

We cut the missing 4 engines out of plywood.

We came up with the idea of stabilizing with impellers on the shoulders at the corners. Impellers are nimble and react quickly to control signals. On their basis, you can assemble an automatic stabilization and control system.

Batteries for the price of a domestic car.

But the impellers weren’t that simple – they also needed a controller, a battery, and wrist-thin wires.

We did not have impellers; we also cut out their models from plywood.

The mass of one turbojet engine is 3 kg. (6 pieces – 18 kg)
The weight of the impeller is 1 kg, the batteries for it are 1 kg, the controller is 1 kg. (4 pieces – 12 kg)
The weight of the “stretcher” and the structure is 5-10 kg.
Kerosene – 30-40 kg.
The thrust of 6 motors is 180 kg.
Fuel consumption: 1 motor – liter per minute, 6 motors – 6 liters per minute.
Flight time is 5 minutes.
Speed - up to 250 km / h.

As a result, 80-100 kg remain for the payload.

What happened in the end:

In principle, we could turn on this thing and hold it in our hands or on strings so that it does not break out. All propulsion electronics and fuel systems work. But then half of the children at the hackathon would be gray-haired.

Usage scenario:

– drive an SUV or snowmobile as close as possible to the scene of the accident.
– pull the “jet stretcher” out of the trunk, mount the frame (5-10 minutes), connect the systems.
– or unmanned we send to the victim if there is a paramedic next to him
– or with a paramedic on board we fly to the victim (1-2 minutes)
– we tie the victim to a “jet stretcher” and send him to an off-road vehicle / snowmobile (1-2 minutes)
