Our "Plug & Play" System

The unique feature: To avoid power failure, we have developed the Duplex version. So you get two identical power systems with homogenous redundancy which keeps you safe in the event of one system failing!

Our powertrain is assembled easily due to innovative plug and play – from the propeller to the battery, you get everything from one source, each part optimally adjusted to the others. In this, we find individual solutions for your applications.

Electrically powered aircraft with a high speed range can only be operated with a fixed propeller or a propeller that is only adjustable on the ground in a restricted speed range with maximum effectiveness.

For this, you need a propeller that can be adjusted in flight. A very light electrically  adjustable 2-blade propeller with a diameter of 1.4m was specially developed for HPD motors and was successfully used in practice on several electric aircraft (e.g. Electra One).

Automatic regulation enables the pilot to carry out the different flight tasks such as shortest take-off, fastest climb, most effective route in the given current weather conditions by pre-selecting the speed.  

Adjusting the pitch of the propeller by the pilot without an  automatic function is also possible.

Motor management

Motor management

The MC300 is a high-performance power inverter with integrated control design that was specially developed for our HPDxx motor range. With our operating devices SDI/ADI, and coupled with the BMS, the system is completely networked and fulfils every flying task. It is designed with a safe operating voltage of  60V DC (PELV - protective low voltage), so that there can be no danger of electric shock to people.

  • Contains algorithms for high availability, safety and ease of operation specially developed for flight tasks.
  • Full part load strength
  • High peak performance , 300A cont. / 400A ca. 3minutes / 600A approx. 30 seconds
  • Multiple modules can be wired in parallel
  • Compensation of the falling battery voltage over the entire discharge range of the battery
  • Reverse thrust possible
  • Energy reclamation in each braking procedure of the airscrew .
  • Continuous communication battery-inverter-motor with self-test function (test of the installation, battery and motor as automatic pre-flight check)
  • Exact current capacity display (guided by temperature and degeneration status) for the pilot
  • Continuous reduction at reaching a limit temperature, no switch-off in the event of wire break etc.  A work point switches itself off at maximum power of the drive, if. e.g.: excess temperatures arise.
  • Solid connections according to industry standards
Steuerung & Software

Control, Interface & Software

The different interface systems ensure optimal operation and display for all aircraft applications.

The interface systems are motor display instruments. motor control interface, recording system (Blackbox), autopilot system and a replacement flight instrument all in one. The ADI also has an integrated pressure sensor, the real time clock, the SD-card of the SDI, an accelerometer and a GPS. extensive data is displayed on the sunlight readable, high resolution touch panel. The SDI represents simple design in restricted space. The ICfly is intended for fitting into a cockpit mushroom with  80mm cut-out and also has a traffic sensor.

The EDriveStudio enables visualisation and analysis of all power and flight data.

The complete system family from the battery through the motor controller to the interface system is parametrised by the Serial Monitor.

The software is available to download at no charge.

The Virtual Coach is an electronic monitoring system for avoiding dangerous operating conditions of electric motors for paragliders carrying people.

The Virtual Coach does not just replace the functions of a conventional mechanical cage but also monitors the entire powered flight for critical conditions and closes the motor down if required or does not permit it to start. 

The Virtual Coach also monitors the tow-up process and supports the pilot with acoustic durch signals and a language output.

Batteries


 

Batteries with integrated BMS and UN38.3 Certification

Li-Ion battery pack in Multimaster operation fully scalable   

Li-Ion battery with integrated BMS and electronic full protection: 
14 Z; 60 Ah; approx. 15 kg  ...  
14 Z; 64 Ah; approx. 15 kg  ...  

available in 2 sizes 
...scalable up to 8 batteries.

The integrated  BMS the task of monitoring the battery in every phase of the operational status and to ensure that the battery is operated within its specifications and is not overloaded.

The basic tasks of the BMS include: cell protection, charging control, load management, determination of the charge status, determination of the cell health, balancing the cells, history, authentication and identification, communication and thermo-management.

Through the integration of the BMS with the battery, it is transportable in the sense of the UN-38.3 Transport regulations.
