Currently doing an assignment which requires me to look at aerodynamic advances in a 787. I have found that the Boeing website is not very detailed when it comes to the new concepts (They dont want ideas copied etc..). They have included smaller fairings, laminar flow nacellle, flaperons, sweptback wings, raked wing tips. I have also read that they are using a new paint type that also helps with the airflow to reduce drag on nacelles
and using HLFC in the tail. 
Basically what I am asking is does anyboy have any more information or facts that would be useful ? Thank you in advance
