Embedded electronically steerable satcom airborne antenna

Periodic Reporting for period 2 - E2S2A2 (Embedded electronically steerable satcom airborne antenna)

Reporting period: 2018-01-01 to 2019-06-30

The project objective is to allow wide band, in flight communication (IFC) through satellite without the need to install any outside equipment. This will be achieved by designing a fully embedded electronically steerable satellite communication airborne antenna.
This will be achieved by replacing the wing to fuselage fairing (WFF) panels with composite material panels that will include the antenna elements.
The fully embedded antenna will allow high data rate IFC minimizing effects on the A/C aerodynamic, performance and fuel consumption.
This will allow connectivity to the A/C for different services without compromising the aerodynamic, the fuel consumption and the air pollution.
This will allow connectivity with minimum affecting the environment.

The introducing of a fully electronically steerable airborne antenna is beyond the current state of the art.
It will allow providing A/C with satellite communication without compromising the A/C maintenance, aerodynamics and drag.
It will allow satellite communication without the need to consume more fuel and undesired CO2 emissions.
The work performed from the beginning of the project included the feasibility design review that resulted in the conclusion that the project objectives can be achieved although very challenging. This was followed by a successful PDR Preliminary Design Review and CDR Critical Design Review and followed by a successful TRR Test Readiness Review. In this review the qualification test procedures were identified and agreed with ADS experts.
In the PDR and later through the CDR the design was presented and reviewed by ADS experts.
A recommended satellite was selected. The satellite was selected mainly due to its link performance at the flight tests planned area.
The link budget was calculated and demonstrated that the link performance could achieve the required performance. In case other satellites will be used, the performance will be adjusted according to the satellite performance.
The system architecture was designed. The MODMAN was selected and the LRUs were defined.
The installation and structural analysis were designed and performed.
The interconnection to the A/C was defined and agreed. it includes the mechanical and electrical interconnection.
The preliminary design phase was completed and resulted in a successful PDR.
This was followed by a detailed design that was resulted in a successful CDR.
The qualification tests for the equipment to ensure safety of flight was planned and agreed.
Qualification tests procedures were written, reviewed and agreed.
This phase was resulted in a successful TRR (Test Readiness Review).
One set of Tx and Rx antenna was manufactured and functionally tested.
The introducing of a fully electronically steerable airborne antenna is beyond the current state of the art.
It will allow providing A/C with satellite communication without compromising the A/C maintenance, aerodynamic and drag.
It will allow satellite communication without the need to consume more fuel and undesired CO2 emissions. If it will be exploited widely, the effect on CO2 emissions reduction will be significant.
Current market solutions provide the communication through the usage of outside of the A/C satellite antenna and thus affect the aerodynamics of the A/C.
It is expected that such solutions will have advantages in the growing IFC market and thus will provide more business to the relevant participants including improving employment opportunities in the EU.
