Technical Memorandum of National Aerospace Laboratory
The blockage correction methods are investigated for low-speed wind tunnel testing on two geometrically similar delta wings with different reference areas. The blockage correction methods used are the classical Maskell method and the simplified tunnel correction method proposed by Shindo. The expression of blockage correction factors in the known classical method is modified to clarify the theoretical meaning of the expression of blockage correction factors in the simplified method. It was concluded, consequently, that the expression of blockage correction factors in the classical method implicates one in the simplified method, and also the total sum of the remainder terms are small due to the offsets of the plus and minus terms.
