1. A horizontal wind tunnel wind force simulator comprising:
a recirculating airflow channel (1), wherein the recirculating airflow channel (1) comprises a first horizontal side member (2), a first airflow turning member (3), a return side member (4), and a second airflow turning member (5);
a horizontal simulator chamber (6) capable of accommodating at least one human during normal use and housed within the first horizontal side member (2) of the airflow channel (1);
a fan (7) mounted in the return side member (4) and configured to generate an air flow;
a contraction member (9) fitted at the inlet side of the first horizontal side member (2), wherein the compression ratio of the contraction member (9) is in the range of 2.5:1 to 1.25:1, and wherein the part of the contraction member (9) is also the part of the horizontal simulator chamber (6);
a diffusor (10) mounted at the outlet side of the first horizontal side member (2), wherein the part of the diffusor (10) is also the part of the horizontal simulator chamber (6);
at least one access point (11) built in the horizontal simulator chamber (6);
wherein the length (A) of the horizontal simulator chamber (6) is longer than the length (B) of any of the turning members (3; 5); and
wherein the length (A) of the horizontal simulator chamber (6) is 0.7 to 1.0 from the length (C) of the first horizontal side member (2).
