01 UAV application field

With the background of the carbon neutral international environment, the impact of aviation equipment on environmental pollution in my country, which has just started not long ago, has become more significant. In order to reduce pollution and maintenance, and to cheaper and more convenient flights, R&D workers have made efforts to turn to power electrification based on the concepts of net zero emissions, rapid energy conservation, and intelligent interconnection. Due to the limitations of pure electric battery technology in terms of energy density, charging time, endurance and cost, pure electric-powered aircraft on the market cannot change the flight status of short range in the short term.

Haery Power's HB4-80 diesel-electric hybrid power unit (80kW class electrical power output) has been used in multiple drones. It has a separate pod power supply method and an onboard hybrid unit form, which helps long-distance, large loads, and higher altitude applications.

The HB4-80 diesel-electric hybrid power unit consists of a heavy oil piston aircraft engine + a relatively speed permanent magnet DC motor. With the support of heavy oil pressure ignition, lightweight design, and relatively pressure common rail, it has the following obvious advantages compared with traditional fuel power and pure electric power:

①Unlimited battery life:Unified oil products (aircraft coal) with large drones, sharing the drone fuel tank, and achieving unlimited battery life;

②Large load:Lightweight design, small size and relatively work-to-weight ratio, making it have a larger load capacity and load space;

③ Attenuation:Heavy oil aircraft engine has a smaller attenuation than the altitude, so that its altitude of 8000m can still maintain 60kW of electrical power output;

④ Improve combat capability: Continuous and stable high-power power supply, providing sufficient energy guarantee for power equipment;

⑤More trustworthiness:Extended range + battery improves the dual guarantee of reliable operation in complex climate environments;

⑥ Achieve short-range take-off and landing capabilities:The motor has strong instant start capability and the thermal efficiency of heavy oil engines is relatively high, which helps to achieve the aircraft's short-range take-off and landing capabilities;

In order to solve the core "mileage anxiety" problem, both at home and abroad are currently closely increasing R&D investment. Whether for military or civilian use, there will be a wide range of application scenarios in the future. Haery Power will continue to increase R&D investment in diesel-electric hybrid extended-range energy platforms to provide a low-cost power solution with large load and long range for aviation vehicles such as drones, general aviation aircraft, and eVTOL.

02 Unmanned Vehicle Application Field

In recent years, with the continuous development of artificial intelligence and sensor technology, more and more unmanned combat vehicles have accelerated toward the battlefield and become emerging forces on the land battlefield. In the early stages of the development of unmanned combat vehicles, due to factors such as short range and poor stability, they played a limited role in the battlefield. As technology continues to be updated and upgraded. In light of the actual needs of the "battlefield", unmanned combat vehicles pay more attention to improving payload capabilities. By equipped with a diesel-electric hybrid extended-range energy platform, it can effectively improve maneuverability and reduce noise, thereby extending combat time.

Haery Power's GV2/MV2 diesel-electric hybrid products have been used in a certain tracked unmanned vehicle and 6×6/8×8 wheel unmanned vehicle and are in small batch production, because of its relatively large power density.Features such as good low temperature performance are highly supported by customers.

Haery Power's diesel-electric hybrid power pack consists of a diesel piston engine and a relatively speed permanent magnet DC motor. With the support of lightweight, relatively pressured common rail and other technologies, it has the following advantages:The following major advantages:

It has become the first choice among many medium and large unmanned vehicles and hybrid products.

03 Unmanned ship application field

my country's sea area is vast and the coastline is long. Marine rights and interests involve many interests such as my country's political sovereignty, territorial integrity, and resource development. However, my country's ocean surrounding environment is complex and disputes over the sea area borders are fierce. Faced with increasingly fierce maritime competition, unmanned ships have become the main force of future maritime application equipment with their characteristics of greater mobility, concealment, low risk and low cost.

The traditional power form of unmanned ships is diesel engines or gasoline engines. With the continuous development of power, information and other technologies, pure electric power ships have only begun to appear in China in recent years, but both powers have certain disadvantages. When traditional power sails at sea, the engine is noisy and the power output is unstable. Pure electric power has irreversible factors such as heavy weight, large volume, and short range. The hybrid system makes full use of the sustainable output performance characteristics of relatively speed engine matching motors, and has obvious power advantages in improving battery life and overall payload.

Haery Power's diesel-electric hybrid power package consists of a diesel engine (depending on the tonnage of the hull, a non-road diesel engine can be selected, or a heavy oil piston engine can be selected) + a motor. With the support of lightweight, heavy hydraulic ignition, FADEC and other technologies, it has the following advantages compared with traditional fuel power and pure electric power:

①Power density:Heavy oil piston engine has the characteristics of relatively high power-to-weight ratio, small size and light weight;

②More silent:The extended range + battery dual power both have the characteristics of low noise and low vibration;

③More maneuverability:It can be fully electric to push, and has obvious advantages in fast start-stop, speed change, reversing performance, small turning radius and short braking distance;

④More fuel economy:Heavy oil has relatively high thermal efficiency and is unified with other equipment oil products. At the same time, the piston engine has low cruising fuel consumption, ensuring low fuel consumption rate and heat loss of boats, and improving the overall operating efficiency of the power system;

⑤Comparison of task completion:It can operate continuously under harsh environmental conditions such as temperature and humidity, with relatively safe and strong environmental adaptability, ensuring that the task is completed with high quality.

⑥More intelligent:FADEC is well connected with the remote controller, and the dual redundant system ensures intelligent matching of the boat.

The diesel-electric hybrid extended-range energy platform product effectively improves the performance characteristics of unmanned ships in large loads, long range, multi-coordination and flexible configuration, and helps military/civilian unmanned ships to grow rapidly in many fields such as ecological and environmental protection, surveying and mapping, hydrology and water conservancy, sanitation and cleaning, maritime inspection and other fields, becoming the main choice for new marine power.

With the continuous progress of informatization and intelligence, the future will definitely be the development trend of unmanned, low-cost and clean energy. The diesel-electric hybrid extended-range energy platform will continue to work with partners in various fields to deepen technology exchanges and cooperation, jointly promote continuous innovation and breakthroughs in platformization, and provide new hybrid platform products with more advanced technology, more trustworthy quality and more convenient application for unmanned equipment and special application scenarios, and is committed to "leveraging".The power is simpler”!
