Pro Avia Twin Engine Passenger Aircraft

The PRO-Avia company has begun a preliminary design of a light multi-purpose twin-engine aircraft for 9-14 passengers

  • Country of origin: Russia
  • Cockpit: 2 seats
  • Wingspan: 1730cm
  • Empty weight: 2200kg
  • Max take Off Weight: 4800kg
  • Take-off distance: 180 metres
  • Landing distance: 170 Metres
  • Max speed: 183kts
  • Range: 1830nm

Key features:
• Fail-safe engine reliability.
• Dynamic utility.
• Significant range.

Whilst as of yet unnamed, the Russian Company Pro-Avia are seeking to realise a concept utility aircraft to supplement, and enable, easy nationwide travel. A light, twin engined aircraft with significant range and load carrying capability would fill a niche that has conventionally been occupied by single engined aircraft.

The aim of the Pro-Avia concept is to create an aircraft that is safe, fuel efficient and reliable, whilst also having a highly effective range. By creating an aircraft that can carry a large amount a long way, the company has sought to make an air travel network available over a wider area, even to places traditionally defined as ‘remote’.

The proposed design of the aircraft by Pro-Avia is as a high wing, twin-engined, monoplane. 

Behind the concept is the fact that two engines give a higher power to weight ratio. Further to this the way in which the engines are positioned increases wing efficiency. By mounting them ahead of the wings, the airflow generated by the propellers, as it flows over the upper surface of the airfoil, augments the lift produced, leading to a shorter take-off run, and better flight characteristics throughout the flight envelope.

Powered by RED A03 Engines

In July 2020 RED Aircraft GmbH has announced that its RED A03 Engine has been incorporated at the design stage of PRO-Avia’s new twin-engine aircraft. PRO-Avia is a Russian company engaged in the implementation, maintenance, and refinement of aviation equipment. RED Aircraft GmbH, on the other hand, is a noted provider of engine and powertrain development engineering services. See press release Game-Changing Piston Engine RED A03 Selected by PRO-Avia For Twin Engine Aircraft

The Benefits of Pro Avia

Another key benefit of the concept behind the use of dual engines is reliability and safety. Whereas a single engined aircraft can be limited in scope, a dual engined aircraft has the capability to continue flying in the unlikely event that one engine becomes inoperative. Increased redundancy in systems as critical as a power-plant is vital, especially as a means of securing consumer confidence and more importantly, safety. This is particularly significant when considering that the aircraft will most likely be operating in areas of high or remote terrain, or heavily forested areas.

Higher power generated by two engines also creates more possibilities for the carriage of an increased payload. Pro-Avia is seeking to accommodate up to 14 passengers aboard its new Utility Aircraft. From a regulatory point of view, this will position the aircraft ahead of it’s competition. Normal regulations dictate that a single engined aircraft can only seat a maximum of 9 passengers. In tandem with the option to carry so many people, comes the possibility for the aircraft to embark upon a wide range of tasks. Cargo transport is a key feature of Utility Aircraft. Depending on final specification the aircraft will hold the potential to carry cargo containers, not to mention being able to perform other roles and more specific activities, such as parachute dropping.
